SatTrack (V4.0)-a real-time satellite tracking and orbit prediction program

SatTrack (V4.0) is a stand-alone satellite orbit prediction and real-time tracking program for UNIX platforms with X Window System color graphics displays. Written in C language, the program displays the location of Earth satellites and provides information for ground station control. A batch mode allows predictions of satellite passes over specified ground stations. SatTrack features the SGP4 and SDP4 orbit propagation algorithms.
