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

The proposed technique relies on two metrics which screen the residual ranging errors in the Zero-Difference and Single-Difference pseudorange measurements with respect to a prefixed threshold.
