Greetings,
Our 3UCubed-A CubeSat was launched on Transporter-15, and we have been attempting to receive beacons from the satellite since, with no luck so far.
The spacecraft transmits beacons every 60 seconds with housekeeping data in ~6 packets of 137 bytes and an interpacket gap of 500 ms at a frequency of 437.01 MHz. Of the 137 bytes, the first 15 bytes are preamble data that can be ignored; starting at the 16th byte is the start of an AX.25 frame ending at the 97th byte.
A couple of observations– Observation 12830962, Observation 12830945, and Observation 12830955, show the general ~60 seconds apart beacon structure; however, the signal seems to be too weak to be demodulated.
Any assistance is highly appreciated.
73,
3UCubed team
