PREDICT is a multi-user satellite tracking and
orbital prediction program. It can provide a
real-time display of data such as a spacecraft's
sub-satellite point, azimuth and elevation
headings, Doppler shift, path loss, slant range,
orbital altitude, orbital velocity, footprint
diameter, orbital phase (mean anomaly), squint
angle, eclipse depth, the time and date of the
next AOS (or LOS of the current pass), orbit
number, and sunlight and visibility information.
