AubieSat-1 designated AO-71

OSCAR Number Administrator, Bill Tynan, W3XO reports that he has advised J. M. Wersinger, PhD, KI4YAU, Professor Emeritus and Director of Auburn University’s Student Space Program, that following the successful NASA ELaNa III launch on October 28, 2011 of AubieSat-1, and by the request of the AubieSat-1 team, the new satellite has been assigned an OSCAR number.

Professor Wersinger documented that telemetry has been received from the satellite. The IARU-Sat Website states that AubieSat-1 was fully coordinated with the IARU.

Bill wrote, “Therefore, by the authority vested in me by the AMSAT-NA President, I hereby designate AubieSat-1 as AubieSat Oscar 71 or AO-71 and welcome this newest OSCAR into the Amateur Radio satellite community.

On behalf of AMSAT-NA and the world’s amateur radio satellite community, I congratulate Professor Wersinger, Auburn University and all of those responsible for building, testing and launching this new CubeSat. May its mission meet with success.”

Jean-Marie KI4YAU asks Amateur Radio operators to listen out for AubieSat-1, on 437.475 MHz CW. He says

We fervently request your assistance in receiving transmissions from an upcoming satellite, AubieSat-1, immediately after its launch from Vandenberg AFB, California, USA. AubieSat-1 (AS-1) is an undergraduate – built CubeSat satellite developed by Auburn University.

AS-1 is designed to transmit with a power of about 800 milliwatts on a frequency of 437.475 MHz, plus or minus Doppler correction [+/- 9 kHz]. The beacon signal, along with telemetry, will be sent using A1A continuous wave Morse code at 20 words per minute. Additional telemetry from the onboard science experiment will use CW transmissions up to 60 WPM.

AubieSat-1 Video

Auburn University’s famous battle cry, “War Eagle”, will be heard from space Oct. 27 when it is transmitted to Earth from a student-built amateur radio satellite known as AubieSat-1.

After launch when the satellite comes over Auburn, Alabama, the team will send up a command and if all is well AubieSat-1 will reply with “War Eagle” in Morse code.

AubieSat-1 is designed to transmit with a power of about 800 milliwatts on a frequency of 437.475 MHz, plus or minus Doppler correction [+/- 9 kHz]. The beacon signal, along with telemetry, will be sent using A1A continuous wave Morse code at 20 words per minute. Additional telemetry from the onboard science experiment will use CW transmissions up to 60 WPM.

The AubieSat team from Auburn University have released a video about the project which features radio amateurs such as J-M Wersinger KI4YAU and Kyle Owen KK4ANG.

AubieSat-1 launch information

Jean-Marie KI4YAU asks Amateur Radio operators to listen out for AubieSat-1, on 437.475 MHz CW, after its launch on October 25 at 0952 UTC:

We fervently request your assistance in receiving transmissions from an upcoming satellite, AubieSat-1, immediately after its launch from Vandenberg AFB, California, USA, 25 October 2011 at 9:52 UTC.

AubieSat-1 (AS-1) is an undergraduate – built CubeSat satellite developed by Auburn University.

AS-1 is designed to transmit with a power of about 800 milliwatts on a frequency of 437.475 MHz, plus or minus Doppler correction [+/- 9 kHz]. The beacon signal, along with telemetry, will be sent using A1A continuous wave Morse code at 20 words per minute. Additional telemetry from the onboard science experiment will use CW transmissions up to 60 WPM.

Based on the pre-launch orbital data provided by NASA, AS-1 will activate after deployment at 12:21 UTC, 25 October 2011. At that time, the sub-satellite point will be at 34.52 S latitude and 1.52 W longitude over the South Atlantic Ocean.

Our predictions are that the first flights over the contiguous United States will begin as shown in the following table:

Orbit AOS Apogee LOS General Locale
3 15:54 UTC >50 deg 16:01 UTC New York
4 17:28 UTC >26 deg 17:35 UTC Texas
5 19:07 UTC >48 deg 19:14 UTC California

This information will be updated should there be launch scrubs or performance changes in the launch, and additional information will be available upon request for specific locations.

Reception reports with data contents are welcomed to the following email addresses:
wersijp at auburn dot edu and tam0013 at auburn dot edu

An internet Echolink conference group is also planned to begin one-half hour prior to launch and continue until about 30 minutes after confirmation of the first receipt of signals from the satellite.

Information on the conference groups title will be distributed nearer to the launch for interested stations.

Please email wersijp at auburn dot edu if you require additional information and can assist in the reception and tracking of AS-1.

Thank you.
