initial commit assumptions: rtl-sdr dongle, stationary antenna goal: record wav files for later processing prerequistes: working rtl-sdr, predict (text based, not gpredict), sox LICENSE - General Public License version 2.0, or any later version dotpredict-predict.tle copy to .predict/predict.tle to get coverage of NOAA-18 and NOAA-19 that is missing in predict's default config noaacapture.py This is the main python script. It will calculate the time of the next pass for recording. It expects to call rtl_fm to do the recording and sox to convert the file to .wav pypredict.py This is a short python module for extracting the AOS/LOS times of the next pass for a specified satellite. It calls predict -p and extracts the times from the first and last lines. update-keps.sh This is a short shell script to update the keps, which are orbital parameters needed by the predict program. It is mostly copied from the PREDICT man page. PREDICT was written by John Magliacane, KD2BD and released under the GPL license.
