satcom:
satcom is a ncurses console application for satellite tracking, with built-in rotor/transceiver control (for the Yaesu G5500 Az/El rotor and Ft-847 transceiver). satcom is based on the sgp4sdp4 package, which is a translation to C of the NORAD SGP4/SDP4 FORTRAN routines and Dr. Kelso's sgp4-plb26a Pascal library. satcom provides a lot of data regarding satellite position, azimuth, elevation, range, Doppler shift, illumination, AOS/LOS etc. It can automatically control transmitter and receiver separately for Doppler shift compensation and Tx/Rx tracking of frequency and mode, for easy operation even on LEO satellites. satcom can help with satellite QSO scheduling since it provides multi-location tracking data, including AOS overlaps, and multi-satellite tracking to provide data for all satellites in its database.
