|Abstract:||The pseudorange signals of GNSS satellites are subject to individual chip shape distortions. As a result, pseudorange observations generated by receivers with different correlator- and/or front-end design exhibit different satellite-dependent biases. This paper will present a detailed study of inter-receiver biases for different GNSS constellations from zero-baseline tests. Both normal correlators and special multipath-mitigation options of different receivers will be tested for legacy and modernized signals. The issue of inconsistent pseudoranges becomes particularly relevant when differential code biases (DCBs) or satellite clock offset corrections are generated based on data from a reference network containing mixed receiver types, as typically done within the International GNSS Service, or with a network of exclusively one receiver type, like a GNSS ground monitoring network or a commercial correction service provider. The effect of inconsistent pseudorange biases on estimated DCBs and satellite clock offset corrections from different receiver networks will be investigated.|
