Robust Square-Root Cubature Kalman Filtering for Relative Orbit Determination of Non-Cooperative Maneuvering Target

摘要

In this paper, a novel-filtering algorithm for the relative orbit determination of non-cooperative maneuvering target is proposed. The algorithm is based on the Strong Tracking Filter (STF) and the Square-root Cubature Kalman Filter (SCKF), called Robust Square-root Cubature Kalman Filter (RSCKF). With the nonlinear orbital dynamics equation as the state model, radar located on the chaser spacecraft as the measurement equipment, the RSCKF is applied for the relative orbit estimation. Simulation results show the superiority of RSCKF over SCKF.
