Hi all,
We are trying to gather a full snapshot of 3 CW beacons from CAPE-1 to get an idea of the health of the satellite. Part of the problem is that we don't know exactly where CAPE-1 is located. TLE's are available on W0RPK's website http://showcase.netins.net/web/wallio/CubeSat.htm about half-way down. We managed to hear a weak signal starting about 435.254 MHz and ending around 435.237 MHz tracking object #31126. We've obtained some information that CAPE may actually be a little behind this one even, but we're not sure.
The satellite is transmitting CW and 9600 baud G3RUH, but currently we are primarily interested in the SSB CW. Also, if you have the capability any recordings are more than welcome. Recordings can be sent to [email protected] If the recording is too large, send me an email and we'll figure out how to get it across. The CW beacon we are looking for the most is the beacon 1 which gives us an idea of battery health. The telemetry format is available at http://ulcape.org/wiki/CAPE1_Telemetry There are a few audio examples at DTUsat's webpage http://www.dtusat.dtu.dk/index.php?id=94 The second file labeled Unknown.wav is what the G3RUH data sounds like in SSB mode and has been confused as the letter N. After that signal ends, the next CW beacon is about 10-20 seconds away.
The satellite is transmitting at 435.245 +/- doppler. Any help would be greatly appreciated. Again any recordings or decoded telemetry can be sent to me at [email protected]
