This work proposes a single augmented Extended Kalman Filter (EKF) to simultaneously and autonomously estimate both spacecraft trajectory and attitude from the Rossi X-Ray Timing Explorer (RXTE) magnetometer and gyro-measured body rates Due to several attitude maneuvers and unknown (disturbances in the measurement data, the final errors could not be reduced further. Future testing on a longer span of RXTE data that is inertially pointing would help to determine the extent of the correlation between the position estimates and attitude error estimates, and additional analysis of the measurement data may identify additional disturbances that could be removed and thus improve the final estimates.
