This paper presents a technique for on-the-fly rejection of GPS pseudorange data outliers. It is developed for applications in whom high accuracy navigation is needed in real time, as for the relative positioning of satellites in Low Earth Orbit. The proposed technique relies on two metrics screening the residual ranging errors in the Zero-Difference and Single-Difference pseudorange measurements with respect to an a-priori threshold. Preliminary tests carried out on flight data from the Gravity Recovery and Climate Experiment mission demonstrate the effectiveness of the proposed approach.
