Abstract

Satellite telemetry, tracking, and control (TT & C) for a user satellite (100) is accomplished using satellites (10, 20, 30) in a satellite communications system as relays. A user satellite includes a modified space subscriber unit (302, FIG. 3) that includes a commercially available, mass-produced subscriber unit (304) modified for use in a space environment. A ground control facility includes a controller (202, FIG. 2) and a ground control facility subscriber unit (218) that includes a commercially available, mass-produced subscriber unit (216). The subscriber units in the user satellite (100) and the ground control facility (70) communicate using the satellite communications system. The relatively inexpensive subscriber units provide TT & C for the user satellite at reduced cost.
