Amateur Radio CubeSats Launch

The Educational Launch of Nanosatellites (ELaNa) initiative took place on Friday, October 28 at 0948 UT and a number of Amateur Radio satellites were among them. The CubeSats were successfully deployed at 1129 UT. Signals have been heard from Explorer-1[Prime], RAX-2, AubieSat-1 and M-Cubed.

APRS Pass Predictor:

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.
