Once \nthe beacon is being received, appropriate software could be used to \ndecode the telemetry.\n\nWith the advent of SDRs now and into the not too distant future, \nthere are more options. SDRs open the possibility of monitoring the \nentire passband, which means that the DSP filtering could \nsimultaneously capture the telemetry, while you're working the \nsatellite somewhere up the passband. This also opens other \npossibilities, such as automatic power control (now there's NO excuse \nto be an alligator!), while collecting that telemetry. Might be a \ngood time for the software developers with DSP experience in the \nAMSAT community to team up with those working on SDRs. The beacon \ncan also be used as a reference for Doppler correction, in case one's \nPC clock is out by several seconds.\n\nTelemetry servers such as the one that was setup for AO-40 could be a \nmeans of gathering all the telemetry, along with some form for \noffline distribution for those who don't have the Internet in their shack.\n\nThe solutions for traditional radios aren't as neat, because of the \nsecond receiver requirement, and the need for it to have computer \ncontrol in addition to the primary gear, but some clever people might \nbe able to come up with something for the masses...\n\n73 de VK3JED\nhttp://vkradio.com\n\n", "attachments": [] }
