Abstract :
The covariance analysis is applied to the performance of spacecraft attitude control systems. Subsystem considered here are the spacecraft bus, attitude controller, reaction wheel assembly, star-tracker unit, inertial reference unit, and gyro drift estimator. The results computed by the covariance analysis are compared with the results computed by the Monte-Carlo simulation. The covariance analysis is shown to be useful for studying the effects of system parameters on attitude control performance.
