TechEdSat: Because the ATV3 did not undock on time, our deployment tomorrow
has been delayed. Please stay tuned for more TechEdSat updates!
I need YOUR help to download AX.25 packets from a NASA CubeSat!
Hello fellow amateur radio enthusiasts,
On September 27th at 9:35AM PDT, our satellite (TechEdSat - KJ6TVO) will
be deployed from the International Space Station. We have a couple of
ground stations in the Silicon Valley, and one in Lithuania (don't ask),
but to get better packet coverage we are enlisting the help of the amateur
radio community to download these packets!
Some technical information:
･ The transmitter will send AX.25 packets once every 4 seconds,
at 100 mW with a minimum gain of -3 dB (tumbling spacecraft)
･ The transmission frequency is 437.465 MHz, linearly polarized
･ Based on our link calculations, if you have a 14 dB antenna you should
be able to pick up packets horizon to horizon, an 8 dB antenna should
get you +15* to +15, and a 3 dB antenna should get you +35 to +35*.
･ The above numbers represent signals that will meet minimum signal to
noise ratio requirements for packet decoding. If you receive a noisy
packet that you cannot decode, we'd love to get audio as well!
･ PLEASE submit all packets here
･ Orbital Elements should be available from NORAD within a few days of
Packets look like this:
