AO-92 to Try Imaging Hurricane Florence September 13-14

AMSAT Vice-President of Operations, Drew Glasbrenner, KO4MA says that the camera on AO-92 is planned to be used to try to image Hurricane Florence during North American east coast passes on Thursday, September 13, and Friday, September 14.

AO-92 will not be in its U/V FM voice transponder operation during these passes. Ground stations should standby and not attempt to access AO-92 during this time. Voice operation will be available later during these days.

The high speed image data will be transmitted on the 145.880 MHz downlink.

The image can be captured, decoded, and uploaded to the Fox-1 data warehouse using the FoxTelem v.1.06 software available from AMSAT:

AO-92 Commissioned, Open for Amateur Use

On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced that AO-92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO-92 was now open for amateur use. Audio of the handover and first operational pass can be heard here:

 

Initially, the U/v FM transponder will be open continuously for a period of one week. After the first week, operations will be scheduled among the U/v FM transponder, L-Band Downshifter, Virginia Tech Camera, and the University of Iowa’s High Energy Radiation CubeSat Instrument (HERCI).

Schedule updates will appear in the AMSAT News Service Weekly Bulletins and will also be posted to the AMSAT-BB, AMSAT’s Twitter account (@AMSAT), the AMSAT North America Facebook group, and the AMSAT website at https://www.amsat.org/satellite-schedules/

AO-92 was launched on the PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India on January 12, 2018. For the past two weeks, the AMSAT Engineering and Operations teams have been testing the various modes and experiments on board. Testing has shown that both the U/v FM transponder and L-Band Downshifter work very well. The Virginia Tech camera has returned stunning photos and data from HERCI has been successfully downlinked.

AMSAT thanks the 178 stations worldwide that have used FoxTelem to collect telemetry and experiment data from AO-92 during the commissioning process. The collection of this data is crucial to the missions of AMSAT’s Fox-1 satellites. Please continue to collect data from AO-85, AO-91, and AO-92.

GOLF-TEE $15,000 Matching Funds President’s Challenge

In October 2017 AMSAT announced the GOLF (Greater Orbit, Larger Footprint) program. The first project of the GOLF program is a technology demonstrator named GOLF-TEE (Technology Evaluation Environment). The design is a 3U CubeSat with deployable solar panels, ADAC (attitude determination and control), Software Defined Radio (SDR) Transponder, and a Vanderbilt University Low Energy Proton (LEP) experiment. Now is the time to begin work on the GOLF-TEE Project.

At the end of 2017, AMSAT has generous offers from two AMSAT Past Presidents for matching funds up to $15,000 for those that contribute to the GOLF-TEE campaign at https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=STK27W4G9RMLC between now and February 15th. Make your donation twice as valuable by taking advantage of this opportunity and contributing, and help AMSAT fund the launch of the next series of satellites of the GOLF program. There are also donate buttons for GOLF-TEE on the AMSAT website. Planning is for a launch in 2019.

Donations of $100 and $1,000 or more will be eligible for a special AMSAT GOLF premium. (Both premiums are currently being designed, so please be patient awaiting delivery.)

AMSAT is a 501-(c)-(3) not-for-profit educational and scientific organization of amateur radio operators whose purpose is to design, construct, launch, and operate satellites in space and to provide the support needed to encourage amateurs to utilize these resources. Please consider a tax-deductible contribution to AMSAT to help underwrite the development and launch expenses of our GOLF satellite program.

Donors wishing to provide additional matching funds please contact Joe Spier, K6WAO at [email protected].

AO-91 Commissioned, Declared Open for Amateur Use

At 06:50 UTC on November 23, 2017, AMSAT Engineering officially commissioned AO-91 (RadFxSat/Fox-1B). AMSAT Vice-President Engineering Jerry Buxton, N0JY, turned over operation to AMSAT Operations in a QSO on the AO-91 transponder with Mark Hammond, N8MH, of the AMSAT Operations team during the pass over the Eastern United States.

N8MH responded and declared AO-91 open for amateur use!

AO-91 was built as a partnership with Vanderbilt University ISDE and hosts four payloads for the study of radiation effects on commercial off the shelf components. The satellite was launched on November 18, 2017 as part of the ELaNa XIV mission, secondary payloads aboard the Delta II rocket that carried the Joint Polar Satellite System (JPSS-1) satellite to orbit. AO-91 also features the Fox-1 style FM U/v repeater with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. Satellite and experiment telemetry are downlinked via the “DUV” subaudible telemetry stream and can be decoded with the FoxTelem software.
