ABSTRACT:
Gyroscopes, particularly those with permanent magnet torquers, may be temperature sensitive. A temperature signal may be derived and used to correct the temperature dependent parameters such as gyro scale factor. Herein, instead of or in addition to such correction, it is proposed to regulate the gyro temperature by varying the torquer signals and hence controlling the power dissipated in the torquer coils. The torquer signals may comprise positive- and negative-going pulses of fixed amplitude and having respective durations appropriate to produce the required torquing effect. Then, the dissipated power can be controlled by varying the durations of the inter-pulse dead-zones.
