38th Annual AMSAT Space Symposium and Annual General Meeting Moving to Virtual Event

The 38th Annual AMSAT Space Symposium and Annual General Meeting in-person event scheduled to be held in Bloomington, Minnesota has been canceled. The event will be shifted to a virtual, online platform. This comes after a decision made between AMSAT’s Senior Leadership and Board of Directors in response to the ongoing COVID-19 pandemic. While AMSAT recognizes the national challenges related to recent events in Minneapolis, they have no bearing on the Symposium decision whatsoever. We anticipate holding 2021’s Annual Space Symposium at the previously announced 2020 venue.

The in-person event was scheduled to occur Friday, October 16th – Sunday, October 18th. As the 2020 virtual event plans are developed, they will be announced via the usual AMSAT channels.

Newly Revised 2020 Digital Edition of Getting Started with Amateur Satellites Now Available

The 2020 edition of AMSAT’s Getting Started with Amateur Satellites is now available on the AMSAT store. A perennial favorite, Getting Started is updated every year with the latest amateur satellite information, and is the premier primer of satellite operation. This definitive reference is written for the new satellite operator, but includes discussions for the experienced operator who wishes to review the features of amateur satellite communications. The new operator will be introduced to the basic concepts and terminology unique to this mode. Additionally, there are many practical tips and tricks to ensure making contacts, and to sound like an experienced satellite operator in the process. The book is presented in DRM-free PDF format, in full color, and covers all aspects of making your first contacts on a ham radio satellite.

Joining the cover art for the first time this year is a depiction of the next generation of AMSAT satellites – AMSAT’s GOLF series of 3U CubeSats.

Amateur Radio on the International Space Station (ARISS) Team in the United States Creates a New Organization: ARISS-USA

In late May, the USA team of the ARISS International working group became an incorporated non-profit entity in the state of Maryland, officially becoming ARISS-USA. This move allows ARISS-USA to work as an independent organization, soliciting grants and donations. They will continue promoting amateur radio and STEAM—science, technology, engineering, arts, and math within educational organizations and inspire, engage and educate our next generation of space enthusiasts.

ARISS-USA will maintain its collaborative work with ARISS International as well as with US sponsors, partners, and interest groups. The main goal of ARISS-USA remains as connecting educational groups with opportunities to interact with astronauts aboard the International Space Station (ISS). ARISS-USA will expand its human spaceflight opportunities with the space agencies, beyond low Earth orbit, starting with lunar opportunities including the Lunar Gateway. ARISS-USA will continue to review and accept proposals for ISS contacts and expand its other educational opportunities to increase interest in space sciences and radio communications.

Becoming an independent organization has been discussed for quite some time. ARISS-USA lead Frank Bauer, KA3HDO said “The scope and reach of what ARISS accomplishes each year has grown significantly since its humble beginnings in 1996. Our working group status made it cumbersome to establish partnerships, sign agreements and solicit grants. These can only be done as an established organization.” Bauer further elaborated, “The ARISS-USA team remains deeply indebted to our working group partners—ARRL and AMSAT, who enabled the birth of ARISS—and our steadfast sponsors, NASA Space Communication and Navigation (SCaN) and the ISS National Lab (INL).” ARISS-USA aims to keep earning high regards from all these partners and sponsors.

While ARISS-USA is now an incorporated non-profit entity, we are in the process of applying for tax exemption as a Section 501(c)(3) charitable, scientific or educational organization. Until that status is approved by the USA Internal Revenue Service, donations made directly to ARISS-USA will not be tax deductible for taxpayers in the USA. Those wanting to make a tax deductible donation for the benefit of ARISS-USA can, in the meantime, continue to make donations to ARISS sponsor AMSAT-NA through the ARISS website at: www.ariss.org.

As ARISS-USA begins a new era as a human spaceflight amateur radio organization, it acknowledges those who were so instrumental in the formation of human spaceflight amateur radio. These include Vic Clark, W4KFC and Dave Sumner, K1ZZ from the ARRL; Bill Tynan, W3XO and Tom Clark, W3IO from AMSAT; Roy Neal, K6DUE a major guide for SAREX and ARISS; and NASA astronaut Owen Garriott, W5LFL. Also remembered is Pam Mountjoy, NASA education, who had the vision to develop the ARISS working group as a single amateur radio focus into the space agencies. All of these giants’ shoulders are what ARISS-USA rests upon.

AMSAT President’s Statement on Creation of ARISS-USA

Announced June 5, 2020, ARISS-USA has been formed as a non-profit corporation to operate independently of The Radio Amateur Satellite Corporation (AMSAT). Since the formation of Amateur Radio on the International Space Station (ARISS) in the mid-1990s, AMSAT has been a consistent supplier of technical expertise, funding, and operational logistics. AMSAT will work with ARISS-USA to ensure a smooth transition for operations and funding.

Over the years, as the scope and activity of ARISS grew, AMSAT continued its financial backing in times of need, providing hundreds of thousands of dollars to fund projects and operations. Many of AMSAT’s members are an integral part of the ARISS team. The human spaceflight element of AMSAT’s vision has been realized through these contributions.

I offer my best wishes to ARISS-USA for a successful future.

AO-73 Now in Full-Time Transponder Mode

After some eight months in continuous sunlight, AO-73 (FUNcube-1) has now started to see some eclipses during each orbit.

The telemetry received has shown that the spacecraft continued to function perfectly during this period and the on board temperatures did not reach excessively high levels.

After this became clear, our next concern was the battery. Having been kept fully charged for this period, would it actually hold a charge and do its job when in eclipse?

After three weeks of increasing eclipse periods we can now see that indeed the Li battery appears to be ok and the bus voltage has not yet dropped below 8.1 volts.

So today we have changed the operating mode from high power telemetry educational mode to continuous amateur mode with the transponder ON. The telemetry continues to be available, albeit at low power.

We will, of course, continue to carefully monitor the data but are planning to leave the spacecraft in this mode for at least the next week. Please enjoy using it!

KG5FYJ Assigned to Upcoming ISS Mission

NASA has assigned astronaut Kate Rubins, KG5FYJ, to a six-month mission to the International Space Station as a flight engineer and member of the Expedition 63/64 crew.

Rubins, along with cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos, are scheduled to launch Oct. 14 on the Soyuz MS-17 spacecraft from the Baikonur Cosmodrome in Kazakhstan.

Among some of the hundreds of experiments ongoing during her mission, Rubins will conduct research using the Cold Atom Lab to study the use of laser-cooled atoms for future quantum sensors, and will work on a cardiovascular experiment that builds on an investigation she completed during her previous mission.

NASA selected Rubins as an astronaut in 2009, she was licensed as a Technician class amateur in 2015, and she completed her first spaceflight in 2016 as an Expedition 48/49 crew member. She launched July 6, 2016, and spent 115 days in space, during which she conducted two spacewalks totaling 12 hours and 46 minutes before her return to Earth Oct. 29, 2016. During her stay on the space station, Rubins helped advance important science and research and became the first person to sequence DNA in space.

Born in Farmington, Connecticut, and raised in Napa, California, Rubins received a Bachelor of Science degree in molecular biology from the University of California, San Diego, in 1999 and a doctorate in cancer biology in 2005 from Stanford University School of Medicine’s Department of Biochemistry and Department of Microbiology and Immunology in Palo Alto, California. Before joining NASA, Rubins worked as a fellow/principal investigator at the Whitehead Institute for Biomedical Research in Cambridge and headed 14 researchers studying viral diseases that primarily affect Central and West Africa.

A New Way to Obtain GP Data (aka TLEs)

The US government has provided GP or general perturbations orbital data to the rest of the world since the 1970s. These data are produced by fitting observations from the US Space Surveillance Network (SSN) to produce Brouwer mean elements using the SGP4 or Simplified General Perturbations 4 orbit propagator.

Many of you are familiar with this data in the form of TLEs or Two-Line Element Sets. TLEs were designed to provide the minimum data necessary to propagate the orbit of a resident space object (RSO) at a time when both bandwidth for transmission or digital storage were extremely limited. In fact, at the time, transmission might be via fax, hard copy (postal delivery), or even read over the phone and storage was handled using punch cards or magnetic tape.

While this format has served us well for many decades, it has not been without its share of problems. For example, the choice of a two-digit year caused many problems approaching Y2K—problems that were side-stepped by redefining what those two digits represented—but that Y2K problem persists fully 20 years into the 21st century. And now we are approaching another milestone where we will no longer be able to catalog all the objects we track within the 5-digit catalog number limitation of the TLE format.

One of the key drivers forcing us to consider tracking more than 100,000 objects is the activation of the Space Fence on Kwajalein Atoll. The Space Fence reached initial operational capability (IOC) on 2020 Mar 27 and is expected to track far more than the ~26,000 objects currently tracked by the SSN—perhaps by as much as an order of magnitude.

And we are expecting to see public availability of data from the Space Fence starting some time this summer (2020). The 18th Space Control Squadron (18 SPCS) has already transitioned internally to using 9-digit catalog numbers in support of these changes and we expect 18SPCS to release data from the Space Fence using 9-digit catalog numbers.

Satellite Shorts From All Over

+ FoxTelem / Fox-in-a-Box Tips: 1) Use a short USB extension cord to physically isolate your SDR dongle from the computer/Pi. There will be less mechanical stress, and a better electrical connection, which will give fewer errors. 2) If you use an RTL-SDR dongle (not really supported, but mostly works), don’t turn on DUV and High Speed at the same time. You will get an error when the decoder starts. Note especially if you have it set up to start when the satellite comes over the horizon.

Temporary Rule Waivers Announced for 2020 ARRL/AMSAT Field Days

ARRL Programs and Services Committee (PSC) has adopted two temporary rule waivers for the 2020 ARRL Field Day to adjust for Covid-19 restrictions. An AMSAT parallel event is held at the same time, and the rules for that have been adjusted, as well.

ARRL Field Day is one of the biggest events on the amateur radio calendar, with over 36,000 participants in 2019, including entries from 3,113 radio clubs and emergency operations centers. In most years, Field Day is also the largest annual demonstration of ham radio, be- cause many radio clubs organize their participation in public places such as parks and schools.

Due to the COVID-19 pandemic, many radio clubs have made decisions to cancel their group participation in ARRL Field Day this year due to public health recommendations and/or requirements, or to significantly modify their participation for safe social distancing practices. The temporary rule waivers allow greater flexibility in recognizing the value of individual and club participation regardless of entry class. The waivers may be found at: https://bit.ly/3de5AJt

The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held con- currently with the ARRL event. The rules for the AMSAT Field Day may be found at: https://www.amsat.org/wordpress/wp-content/uploads/2020/05/2020fd.pdf

This will mean that there will be another group of certificates for AMSAT Field Day: The top three stations operating from home with commercial power.

The problem is with those operating from home attaching their scores to a club. Because AMSAT only allows one satellite station to be operating at a time, if you are going to attach your satellite contact to a club, only ONE home station can attach per club. This will keep the playing field rather equal as there are areas where there is only one satellite op around and other areas where there are dozens of satellite ops. It would be unfair for an area with a dozen satellite ops to pool all their home contacts towards one club.

Even if satellite operators took turns operating in shifts, it would make it very difficult to score entries correctly. That is why AMSAT has chosen to allow only one satellite home station could be attached to a single club. CLUB NAME MUST BE IDENTIFIED IN THE ENTRY.

There will also be no duplicate certificates. If you are attaching your score to a club, then it goes towards club rankings and not home rankings. Nothing needs to be changed on the submission form. If you are operating 1D and the name of your attached club is included, the club score will be calculated appropriately.

This is new and uncharted waters and hope everyone enjoys AMSAT Field Day. A much larger number of entries is anticipated with this change, so patience is appreciated.

Digital Mode Experiments Conducted on Linear Satellites

[EDITOR’S NOTE: Be aware that the experiments described below utilize very narrow AFSK modulation with fairly advanced computer control for Doppler correction and frequency stabilization. They do NOT involve use of narrowband FM signals such as those used for terrestrial APRS or dedicated APRS satellites. So please, NEVER transmit FM on the uplink to a linear satellite. ALSO, in should be emphasized that power levels must be kept very low, as all the WSJT modes are 100% duty cycle.]

Recently a group of regular satellite-using amateurs conducted experiments with FT-8 and FT-4 on a variety of linear satellites.  Alan (WA6DNR), Carlos (W7QL), Dave (W0DHB) and Ron (W5RKN) were involved and made many satisfactory QSOs.   The primary results and observations from these tests are:

  • Digital modes can successfully be employed on the linear birds while not interfering with concurrent users by operating close to the bottom end of the passband, using the lowest power practicable and using very narrow signals.
  • We avoided the satellites known to be power-sensitive, FO-29 and AO-7. Testing was conducted with CAS-4A, CAS-4B, RS-44, XW-2A, XW-2B, XW-2C and XW-2F.
  • FT-4 was the most robust signal format, compared to FT-8. Other of Joe Taylor’s digital signal modes should be investigated.
  • The rate of change of Doppler just before and after TCA is high on the lower-orbit satellites and must have compensation. 200 Millisecond Doppler updates allowed 100% copy of FT-4 transmissions throughout several passes of different linear satellites.  This can be accomplished in SatPC32 by setting the “SSB/CW Interval” in the CAT menu to zero and checking the 5X box.  Note that this setting is not retained when SatPC32 is shut down.
  • Very little power is needed for QSOs throughout the duration of the pass, from AOS to LOS. W7QL set IC-9700 power to “zero” (roughly 500 milli- Watts, with over 3 dB cable/connector loss to a Leo-Pack antenna pair) and copied every packet on several satellites.
  • FT-4 is very tolerant of voice signals which might drop on top of an ongoing FT-4 QSO. However, an FT-4 signal dropping in the middle of an SSB QSO would be quite annoying to the SSB operators.
  • According to Joe Taylor, the occupied bandwidth of an FT-4 signal is 90 Hz. So theoretically over 200 such signals could be present on a 20 KHz channel.   Obviously that will not, and should not happen.   But a dozen closely spaced FT-4 QSOs at the bottom of the band, each running very low power should hardly be noticeable to current voice and CW traffic.

We invite other Satellite operators to join us in this expanded utilization of the linear satellite resources available to us.  We recommend using FT-4 at very low power, in the bottom few KHz of the downlink frequency range, with appropriate Doppler compensation, as described above.  We hope to have a digital QSO with you sometime soon on the linear birds.

SpaceX Launches Successfully Toward ISS

NASA astronauts Bob Behnken, KE5GGX, and Doug Hurley boarded a Crew Dragon spacecraft on top of a Falcon 9 rocket once again on Saturday, May 30. At 19:22 UTC they were successfully launched on their way to the International Space Station. This was the first launch of astronauts from U.S. territory since the final Space Shuttle flight in 2011 and the first launch of humans by a private contractor, SpaceX.

The first attempt for the launch, on Wednesday, May 27, scrubbed due to stormy weather near the Kennedy Space Center in Florida. The Crew Dragon spacecraft is scheduled to dock with the ISS about 19 hours after liftoff.

FT8 co-developer Joe Taylor, K1JT, has reported what is possibly the first FT8 contact via moonbouce (Earth-Moon-Earth or EME) on May 21 between Paul Andrews, W2HRO, in New York, and Peter Gouweleeuw, PA2V, in Netherlands. The contact was made possible using the currently available beta-release candidate of WSJT-X, version 2.2-rc1.

“Why might you want to use FT8 instead of ‘Old Reliable JT65’ for EME QSOs?” Taylor asked in a subsequent Moon-Net post. “FT8 is about 4 dB less sensitive than JT65, but with 15-second T/R [transmit/receive] sequences it’s four times faster, and it doesn’t use Deep Search,” he said, answering his own question.

The FT8 protocol included in the beta version of WSJT-X has an optional user setting to work around the 2.5-second path delay. “For terrestrial use, the FT8 decoder searches over the range -2.5 to +2.4 seconds for clock offset DT between transmitting and receiving stations,” Taylor explained. “DT” represents the difference between the transmission time and actual time. “When ‘Decode after EME delay’ is checked on the WSJT-X ‘Settings’ screen, the accessible DT range becomes -0.5 to +4.4 seconds. Just right for EME.”

As Taylor explained in his post, FT8 uses 8-GFSK modulation with tones separated by 6.25 Hz. At the time of the contact, the expected Doppler spread on the W2HRO – PA2V EME path was 8 Hz, which would cause some additional loss in sensitivity. Despite the path losses, however, copy between W2HRO and PA2V was “solid in both directions,” Taylor said.

Taylor said that when he was active in EME contests on 144 MHz, he was always frustrated that, even with reasonably strong signals, the maximum JT65 contact rate is about 12 per hour. “With FT8, you can do 40 per hour, as long as workable stations are available,” he said.

As for using FT8 for EME contacts on 1296 MHz, Taylor said it “might sometimes work, but Doppler spread will probably make standard FT8 a problem.” Given sufficient interest, however, he said the WSJT-X development team could design an FT8B or FT8C with wider tone spacing. He encouraged the use of FT8 for moonbounce on 144, 432, and 1296 MHz and asked users to report their results to the development team.

“A ‘slow FT8’ mode is indeed a sensitivity winner on suitable propagation paths,” he said in a later Moon-Net post. “We are busy implementing such a mode, but with particular emphasis on its use on the LF and MF bands.”

Taylor said FT8 has the operational advantage of putting all users in one (or a few) narrow spectral slices on each band. “So, it’s easy to find QSO partners without skeds or chat rooms,” he said. “Everything is done over the air, with no ‘side channels’ needed.”

Taylor also remarked in response to posts from those who, like him, “love CW.”

“I agree it’s a thrill to hear your own lunar echo, and to make CW EME QSOs,” he said. “Sometimes I pine for the bygone world of commercial sailing ships, which happen to be very much a part of my family’s his- tory,” Taylor concluded. “But I know that technologies evolve, and the world does not stand still.”

Mid-Altitude Balloon Race Planned for June 1

Three Space Station Explorer teams will participate in an exciting distance learning—social distanced balloon race to beheld during the Pandemic.

ARISS educator, Joanne Michaelis, KM6BWB, is a science coach at the Wiseburn Unified School District in Los Angeles, California where she leads her students in several balloon launch attempts from the Los Angeles area each year. With this year different because of the pandemic, Joanne wanted to “shake things up a bit” and give students world-wide, a unique distance learning treat while keeping all safe during the pandemic. So Joanne challenged Ted Tagami, KK6UUQ, from Magnitude.io to a mid-altitude cross-continent balloon race and Ted accepted the challenge!

Ted plans to launch his balloon from Oakland, California. ISS Above inventor, Liam Kennedy, KN6EQU, from Pasadena, California, got “wind” of the idea and he asked to participate, too. All three organizations: ARISS, Magnitude.io and ISS Above are ISS National Lab Space Station Explorer (SSE) partners that work to inspire, engage, and educate students in Science Technology Engineering, Arts and Mathematics (STEAM) topics and to pursue STEAM careers.

The three SSE teams plan to launch their balloons simultaneously on June 1. The winner will be the first one to cross the“Finish Line”—the Eastern Time zone. Launch time is planned for 15:00 UTC (11:00 EDT, 10:00 CDT, 9:00 MDT, or 8:00 PDT. A live video feed of the launch is planned to start approximately 5 minutes prior to the event.

Once the balloons are airborne, students can track each balloon’s location, altitude, and temperature via amateur radio APRS (Automatic Packet Reporting System) which is fed automatically to the aprs.fi web site. Educators and parents around the globe can excite at-home youth with this initiative. Students can tally and track the states each balloon travels through and plot altitude versus temperature, etc. Also, by researching weather patterns, students can make assumptions from their own data. This could include speed variations due to weather.

They also can predict each balloon’s flight path and when they might cross the finish line!

For more information on the balloon launch, lesson plans, and the livestream video link (when the livestream URL is available), please go to: https://www.ariss.org/mid-altitude-balloon-race.html

Enjoy the Race! May the best ballooner win!!

Upcoming Satellite Operations

W8LR: (@W8LR) May 30 and May 31 he will attempt to activate a dual grids contact. The grid line will be EM79/EM89.

Hey you guys from the EU: @N4DCW will be in EM56 June 5-7 with a semi- decent N-E horizon from his sister-in-law’s house. He will be on RS-44 and AO-7 looking for y’all.

AD0DX: (@AD0DX) DM77 and maybe DM76 on Saturday May 30.

An interesting email from ND9M/KH2: I’m finishing up my current tour on a U.S. merchant marine ship cur- rently anchored at Guam. I’ve been QRV from the anchorage which is at Apra Harbor. We’ll be taking a one-night run on June 2-3 to give the engines a chance to stretch their muscles. I expect to be QRV on sever- al passes on the evening of June 2 when we should be in QK13 for a few hours. Once we return to “the hook,” I’ll start packing up for my trip back to the States that weekend and should be doing some roving in the eastern states (MD, PA, VA, MD) once I get my body re-adjusted to the the 14-hour time change. Major Roves:

Ron (@AD0DX) and Doug (@N6UA) are making another run at the elusive DL88 in Big Bend National Park, TX. As we know they tried this grid back in March, and due to the mud couldn’t get to the grid, so never ones to quit, off they go again. Today the tentative date is Sunday May 31, 2020. They will be using the K5Z call sign. More information is available at the K5Z QRZ Page.

FP, ST. PIERRE & MIQUELON (Rescheduled). Eric, KV1J, will once again be operating from the Island of Miquelon (NA-032, DIFO FP-002 WLOTA 1417, Grid GN17) as FP/KV1J between September 22nd and October 6th. This oper- ation was originally scheduled for July, but was postponed due to trav- el restrictions. It will be Eric’s 14th trip to the island. Activity will be on 160-10 meters, including 60m , using CW, SSB, RTTY, FT8/FT4 (but primarily SSB, RTTY and FT8/FT4) and the SSB/FM satellites. He will generally be on the highest frequency band that is open (favoring 60/12/10/6m). He will be active in the CQWW DX RTTY Contest (September 26-27). ADDED NOTE: Eric will usually try to be on as many Satellite passes as he can when the WX is good, generally favoring the XW-2x, AO-7, RS-44, CA-4x, and possibly the FM birds. Weekends may be limited since he will be concentrating on the low(er) bands and contests. QSL via KV1J, direct or by the Bureau. Also eQSL and LoTW.

AMSAT Announces 2020 Field Day Rules

It’s that time of year again; summer and Field Day! Each year the American Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!” The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event.

For 2020, the event takes place during a 27-hour period from 1800 UTC on Saturday June 27, 2020 through 2100 UTC on Sunday June 28, 2020. Those who set up prior to 1800 UTC on June 27 can operate only 24 hours.

AMSAT Director of Contests and Awards Bruce Paige, KK5DO, has an- nounced the rules for the 2020 event.

Paige notes that “AMSAT has followed the ARRL when it comes to the date, times and most rules with regard to Field Day. [ARRL has made some modifications due to COVID-19]. With that in mind, AMSAT is going to have to adapt as well.”

Paige further elaborates, “What we will do for AMSAT Field Day is con- centrate on rovers and operating from home.” In line with this new concentration, the awards issued this year will be modified. The top three club stations will receive certificates as will the top three stations overall (instead of the top three home operators on emergency power). AMSAT will also award certificates to the top three roving stations.

The 2020 rules can be found at https://www.amsat.org/field-day/.

AO-27 Returns from the Dead

A number of amateurs have reported that the FM repeater of AO-27 has been active for brief intervals in recent weeks. When commanded on by control operators, the transponder is active for about two minutes before reverting to telemetry transmissions only.

Patrick Stoddard, WD9EWK, remarks that AO-27 wasn’t originally intended to be an FM satellite. It lacks the audio filtering normally seen with a n FM receiver, since its uplink receiver was going to be used for data. With the lack of audio filtering on the uplink receiver, AO-27 was used for tests with D-Star radios.

The Wayback Machine has captures of the former ao27.org web site, detailing how those tests were done. Two radios were used for those D- Star QSOs, one for uplink and the other for downlink).

Many are hopeful that control stations will eventually be able to recover the satellite sufficiently to provide more regular operation. In the meantime, if you hear the satellite active, make your contacts quickly!

Updated GOLF Project Information Available

The AMSAT website has posted updated information on the next series of satellites, intended to succeed the current Fox satellites. AMSAT is developing a satellite program that should see amateur transponders in Low Earth Orbit (LEO), Medium Earth Orbit (MEO) and eventually High Earth Orbit (HEO)

GOLF is an acronym for “Greater Orbit, Larger Footprint”

The goal of the GOLF program is to work by steps through a series of increasingly capable spacecraft to learn skills and systems for which we do not yet have any low-risk experience. Among these are active attitude control, deployable/steerable solar panels, radiation tolerance for Commercial off the Shelf (COTS) components in higher orbits, and propulsion.

The first step is to be one or more Low Earth Orbit (LEO) satellites similar to the existing AO-91 and AO-92, but with technologies needed for higher orbits. With proven technologies, an interim high LEO or Medium Earth Orbit (MEO) satellite would follow on.

The eventual goal is a High Earth Orbit (HEO) similar to AO-10, AO-13, and AO-40, but at a currently affordable cost combined with significantly enhanced capabilities which in turn will allow the use of much less complex ground stations.

Changing HuskySat-1 Keps Name in FoxTelem

Instructions for updating FoxTelem (including Fox-in-a-box) so that HuskySat-1 keps are now downloaded as HO-107.

Go to the Spacecraft menu and select Husky (or something else if you have changed the name). In the upper left is a section that says “Name (for Keps)” and the box to the right should say “HuskySat-1”. Just change that to HO-107. Done.

Note that HuskySat-1 is no longer in the downloaded keps, so the one you have will get older and more out-of-date until you change the name. Don’t forget you will need to do something similar with MacDoppler or SatPC32 or any other tracking program you have.

Hack-a-Sat Team Boasts Exceptional Participation

The Vaporsec “Capture The Flag” (CTF) team, specifically open to amateur radio operators, has seen the largest turnout for a CTF competition in team history, for this satellite-themed event. We have over 20 signed up for the qualifications event this coming weekend. We believe that based on the diversity, quality, and positive can-do spirit, that we have a chance at being competitive and moving on to the final round in late summer.

We had a successful team organizational meeting last night are are looking forward to a Friday 5pm Pacific start time. I’m looking forward to being able to share how amateur radio operators and practical experience carried the day!

The point of the competition seems to be the Air Force wanting to see that the current level of competence is out there with respect to satellite operations and security. Hints have included backgrounders on ADAC, Satellite IoT platform security, protocols, ground control, and more. Rules and link to the Hack-a-Sat website are at: https://www.hackasat.com/

Something that we noticed is that an unsolved challenge in last weekend’s DEFCON CTF qualifier round was from the same team that is putting on Hack-a-Sat CTF.

So! If you are wondering what kind of challenges are posed to participants in a CTF, here is that satellite-themed challenge. We expect this sort of thing to be the starting point for an entire weekend of satellite reverse engineering, puzzle solving, and rogue-craft-wrangling.

There are two files related to the challenge. The challenge text and the two files can be found at: https://bit.ly/2yrFlQM

See you on the other side of the CTF! We will have a write-up of the event and share any and everything we learn along the way.
