Scientific paper
The accuracy of spacecraft attitude determination systems using laser gyros and gas bearing gyros is compared for maneuvering and nonmaneuvering spacecraft. Theoretical attitude determination accuracy comparisons and computer simulation results are presented along with reliability and cost comparisons. The dominant laser gyro error source is the attitude random walk which occurs with electromechanically dithered laser gyros. The viability of laser gyros for precision stellar aided spacecraft attitude determination systems is shown. Major emphasis is placed on the performance aspects of the laser gyro, noting that the advantages for maneuvering spacecraft are a good scale factor and alignment stability, which reduce the attitude determination complexity.
