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.
