Telecommunications Description

The mission requirement for real time operations implied a geosynchronous orbit so that the satellite was continuously visible from the ground station at GSFC and was visible from the European ground station for at least 10 hours per day. the data are telemetered in real time to ground stations at GSFC and Villafranca, Spain. The two most common telemetry rates are 20 and 40 kb/sec. Commands are uplinked at 800kb/sec.
