HI everyone, another new tracking module that now integrates with GNURadio I just released here:
Skytrack takes signal tracking out past gpredict with earth-based satellites and allows tracking (doppler frequency shifts and azimuth and elevation) out to solar system bodies (thanks to the python skyfield library). Use case: pointing an antenna at the Moon or Mars. It talks seamlessly to the new gr-gpredict-doppler GNURadio modules I pushed last week (
https://github.com/ghostop14/gr-gpredict-doppler.git) to bring live doppler frequency updates into GNURadio.
It's a little "rough" as a python script, and the skyfield library went through some updates late last year, but let me know if anyone has any issues.
One more set of new modules I'm working on that I'll try to push hopefully before summer will pull a bigger picture together with a GNURadio block that can monitor inbound power and provide state output, and an input selector that integrates with it to automatically switch receivers based on signal strength to select the best receiver/antenna for a particular frequency.
Ultimate goal/Big Picture: Multiple receivers monitoring the same space-based signal that can automatically select the best input based on power, and only record to file (using the new gr-filerepeater enhancements) when the signal should be (and is) present. All this because I'm lazy and don't want to have to keep moving my antenna with North/South passes or have to keep running to my computer with each pass to start/stop recording a pass!
