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.
