This is a compact satellite tracking program. Using it even an older PC (from 486 up, DOS, VGA) can serve to track a satellite and turn the antenna, which allows newer PCs to be used for other purposes. For example other software can be used in parallel to get more information on multiple satellites or contact ranges. It has the following functions needed in satellite communications: Tells in which direction the satellite is. Prints the azimuth and elevation angle numbers to the parallel port for automatic tracking (8 bit parallel data). Gives pulses to two LPT pins for automatic doppler correction (up / down). -This is a compact satellite tracking program.
