Abstract:

The digital infrared earth sensor (IRES) is an important component of the geostationary earth orbit (GEO) satellite control system.IRES is used to measure the satellite attitude.Its outputs are used to compute the control torques for satellites.The IRES have four bolometer detectors.The attitude of any Chinese GEO satellite in orbit is determined using the information of three bolometer detectors at least.This paper develops an attitude determination method using two bolometer detectors only and gives an application strategy based on the real situation.With this method, the IRES application range is expanded, the redundancy is enhanced, and the lifetime is increased.
