Influence on Modeling Errors Associated with the Attitude Reconstitution for Spin-Stabilized Satellites in Order to Provide Optimal Estimation Techniques

摘要

One method employed for spinning spacecraft attitude reconstitution from albedo fan beam sensor measurements is the extended Kalman filter. The filter measurement residuals from the COS B satellite were investigated. It is concluded that deficiencies in the filter system model exist and an alternative filter solution is sought. Current filtering methods based upon Kalman theory were surveyed, and an alternative method, i.e., the J adaptive filter, was chosen. Rigorous testing of the J adaptive filter reveal considerable areas of weakness in this application. A further parametric study based on geometric considerations was conducted. Results show that it was not possible to isolate a single cause or causes which consistently explain the observed behavior of the residuals.
