Autonomous Deep Space Navigation Based on Electric Propulsion
Presented herein is a concept of autonomous navigation research in the orbit of the minimum-fuel , interplanetary transfer performed by the electric propulsion. With lunar mission background, the orbit transfer is modeled by the dynamics of the classical restricted three-body problem in a mooncentered, rotating, orbit plane coordinate frame. More realistic and complex orbital perturbation factors had been considered in this article. The errors in the model of dynamics and process noises had been analyzed in The Unscented Kalman filter(UKF) based on measurements of the star angle massage. The divergent problem caused by the coupling of propulsion direction and deviation of spacecrafts state estimate errors is reduced to expected level by fading memory method and cutting down dimensions of propulsion directions in the Unscented Kalman Filter algorithms.
