Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A775104. The abstract provided by the Pentagon follows: This study adapts some established attitude determination techniques for use with star tracker measurements on satellites. Other work in this area has utilized gyro measurements with star tracker updates. Today's star trackers are giving measurements with accuracies of less than 6 arcseconds, and are therefore of high enough fidelity to be used alone. Computer simulation of a Linear Kalman Filter to process these measurements is presented. The Filter uses a linear, constant coefficient state matrix with the Optimal Control Law to provide negative feedback control. The control law uses information developed through the equations of motion of the spacecraft in a Molnyia orbit. Modifications to the Filter, including glitch rejection and various covariance manipulation techniques are discussed as possible sources for performance enhancement.
