STSAT-2B

Wiki

The primary instrument aboard STSAT-2B was the Dual-channel Radiometer for Earth and Atmosphere Monitoring, or DREAM, which would have measured the brightness temperature of the Earth at 23.8 GHz and 37 GHz. The secondary payload, the Laser Retroreflector Array or LRA was to have been used for the Satellite Laser Ranging experiment, which was intended to determine the parameters of the satellite's orbit with a greater degree of precision. Data collected by the secondary payload would have been used to calibrate DREAM, to conduct geodetic research, and to evaluate the performance of the carrier rocket. Due to lower manufacturing tolerance, the retroreflectors on STSAT-2B would have provided greater precision than those intended on STSAT-2A. A series of technological experiments were also to have been conducted; investigating attitude control systems, and testing pulsed plasma thrusters, star trackers, a Sun sensor, as well as an experimental onboard computer, and data relay at rates of up to 10 megabits per second.
