Spin-Axis Attitude Determination Program for the Geosynchronous Transfer Orbit Spacecraft

Abstract

Three types of spin-axis attitude determination program for the geosynchronous transfer orbit spacecraft are developed. Deterministic closed-form algorithm, batch least-square algorithm and stabilized Kalman filter algorithm are used for implemetation of three programs. EUROSTAR bus model from Birtish Aerospace is used for attitude sensor modelling. Attitude determinations using three programs are performed for the simulated sensor data according to INMARSAT 2-F1 prelaunch mission analysis.
