Abstract Trajectory estimation using the measurement of arrival angles from space-based infrared sensors is one of the key technologies in the space early warning system. This paper presents a pseudolinear measure-Kalman estimator for trajectory estimation in boost-phase. Compared with EKF and CRLB, this estimator is more precise.
