AO-51 Operations Team Says New Power Control Settings

BID: $ANS-157.03

AMSAT-NA VP Operations, Drew KO4MA reported on the current status 
of AO-51. The satellite is currently operational with the main V/U 
repeater, 67 Hz PL enabled.

June 1 - June 21 FM Repeater, V/U
Uplink:   145.920 Mhz FM, PL 67Hz
Downlink: 435.300 Mhz FM

The power management routine adjusts the power output in three stages 
based on illumination state and battery voltage. The high setting is 
1.57 watts. The mid-setting is at 290 mw, and the low setting is off. 

During passes over the eastern US, especially in the morning, the Op-
erations Team has been collecting telemetry on the 435.150 transmitter, 
so users may have heard the power levels toggle on 435.300. The rest 
of the time outside of eclipse it should be pretty steadily at the high 
setting. Soon after entering eclipse, if in use, the transmitter will 
shut off. Please do not use AO-51 when it is in eclipse.

Eclipses continue to lengthen until about July 1, then drop back to 
zero by the third week of August. This last period of continuous 
illumination will last until January 2011. AO-51 will likely only be 
operational while illuminated after this date.

Drew thanks Mark Hammond N8MH, Kevin Schuchmann WA6FWF, and Jim White 
WD0E for their help with the satellite during this period of rearrang-
ing our operational plan, and learning new tricks to keep AO-51 
available as much as possible. We are approaching 6 years in orbit!

AMSAT-OH Reports P3E S/X Band Transponder Prototype Operational

AMSAT News Service Bulletin 157.04

To All RADIO AMATEURS
BID: $ANS-157.04

Michael, OH2AUE has written the latest news of the AMSAT-OH S/X band 
coherent/linear transponder for P3E project. The Coherent mode is a 
fully functional testbed for the P5A ranging transponder.

The Finnish team meets on a regular basis every 4 - 6 weeks for 
testing and to followup on the work of each individual. The team has
assembled the linear transponder prototype and verified it with over-
the-air tests and laboratory tests. Flight versions of the submodules
are being produced at this time with the goal of integrating them and
cabling the S/X transponder.

Full verification of the Coherent Mode is awaiting a fully functional 
command station AND a functional IHU + CAN environment. Preliminary 
testing and evaluation of the Coherent Processor have shown proper oper-
ation of the design and circuitry (e.g. locking onto a "modulated" 
uplink carrier, tracking this etc.).

The general design, block diagrams, and photos can be found on-line at:
http://www.rats.fi/rats/amsat-oh/  It is currently in Finnish but the
team hopes you will enjoy it.

This transponder is especially complex as you can see from these key 
on figures on the web page:

     * 9 different local oscillators
     * All local oscillators locked to the common 10 MHz USO
     * 21 different frequency mixers
     * 13 different intermediate frequencies
     * Linear Mode output power on 10 GHz: 3 W PEP
     * P5A Mode output power on 10 GHz:  1 mW PEP
     * 38 control lines on the CAN interfaces
     * 2 CAN interfaces, one in multiplexed mode
     * 4 dedicated direct control lines interfacing with the IHU
     * 14 analogue telemetry lines to the CAN bus
     * Coherent Mode Uplink/Downlink ratio is fixed at 30:7

Michael concludes, "Our team sincerely hopes funding will eventually be 
found for P3E/P5A - this is the only thing that keeps us motivated to 
continue our work. On the other hand we are clearly behind schedule, so 
the delays are welcome. But then again, any news of progress would boost 
our production rate phenomenally!"

Canberran Students Enjoy ARISS Ham Radio Contact

AMSAT News Service Bulletin 157.05
>From AMSAT HQ SILVER SPRING, MD.

BID: $ANS-157.05

A very successful Amateur Radio on the International Space Station 
(ARISS) was completed this week. Jim Linton, VK3PC provided this
information to the SouthGate ARC News site; the story is reprinted
below:

Ten students from the Trinity Christian School at Wanniassa in the 
Australian Capital Territory made history at the weekend with the 
first Amateur Radio on the International Space Station (ARISS) pro-
gram contact to be held in Canberra.

The event was part of the Wireless Institute of Australia (WIA) 
centenary dinner attended by 200 people including international 
guests, Australian Communications and Media Authority Chairman Chris 
Chapman, and WIA Centenary Patron Dick Smith VK2DIK.

A telebridge ON4ISS in Belgium (operator Philippe Van houte, ON5PV) 
made the contact with ARISS Asia-Pacific Coordinator, Tony Hutchison 
VK5ZAI at the controls in Canberra for the contact on Saturday, 29 May.

The audience remained quiet and listened intently as the Year 12 stu-
dents asked Astronaut and Flight Engineer Tracy Caldwell-Dyson KF5DBF, 
on her assignment on the space station, a series of questions.

The session began with a brief speech by Tracy who congratulated the 
WIA on its centenary and commented briefly on amateur radio's history 
and amateur satellites.

Student William Shaw, asked: When you are in space, are you "above" 
the law? If there was a legal issue that arose on the space station 
which nation's law would apply?

Tracy replied that she did not foresee that there would be a legal 
problem on the space station and added that there were controls on 
what could occur in space.

Another student, Elizabeth Shen, asked about living is space with 
zero gravity, its effects on the body and whether there were changes 
to the normal blood pressure and pulse rate.

It was learnt in Tracy's response that the crew are constantly moni-
tored, there are effects and rehabilitation on return to earth can 
take up to three months.

In other questions the topics of sleeping in an environment with 16 
sunrises and sunsets a day, space walking - Tracy is to have that 
experience soon - and the potential for collision with solid matter 
in space.

After the ARISS contact Elizabeth Shen and William Shaw said they were 
both extremely impressed by the efforts made by astronauts to qualify 
and fly in space, giving them encouragement to strive in their chosen 
careers.

Elizabeth, aged 17 added: 'The opportunity to speak to someone above 
the space station was one of the best experiences in her life.'

While William, aged 18, said 'It was really cool to be able to talk to 
someone who is in a completely different situation - with the zero grav-
ity and what not.'

Trinity Christian School Principal, Carl Palmer VK2TP/VK1TP was justi-
fiably very proud of his students.

WIA President Michael Owen VK3KI presented each with a participation 
certificate. WIA Centenary Patron Dick Smith VK2DIK - aviator, advent-
urer and entrepreneur - shook their hands, spoke to them about their 
experience and had his photograph taken with them.

In addition to regular membership, AMSAT offers membership in the
President's Club. Members of the President's Club, as sustaining donors
to AMSAT Project Funds, will be eligible to receive additional benefits.
Application forms are available from the AMSAT Office. And with that,
please keep in mind this advice to a student pilot, "A thunderstorm is 
never as bad on the inside as it appears on the outside. It's worse!
If you push the stick forward, the houses get bigger, if you pull the 
stick back they get smaller. Try to keep the number of your landings 
equal to the number of your takeoffs."
