“…Kalman filter (KF) is widely used in processing kinematic geodetic measurements (Bogatin and Kogoj 2008). For linear systems with Gaussian noises, KF is optimal in almost every conceivable sense (Simon 2006).…”

A robust Kalman filter based on Chi square test with sequential measurement update is proposed. This approach can not only handle outliers in part or even individual measurement channel, but can also further improve the accuracy especially when a novel ordering strategy in processing the measurement elements is adopted. The accuracy improvement can be attributed to the higher statistical efficiency, i.e., an increased probability of correctly resisting the outlying measurement elements and retaining the good ones. The accuracy improvement of the proposed method is illustrated by a simulating example.
