GNSS software defined receiver pseudorange error assessment

Abstract

SDR approach, applied to the field of GNSS, allows the implementation of high customizable low-cost GNSS Software Defined receivers. These can reveal as useful tools for navigation algorithms prototyping. In the FOSS scenario the most interesting SDR appears to be GNSS-SDR. In this paper we evaluate GPS L1 pseudorange error GNSS observations acquired by SDR; for this purpose a low-cost COTS u-blox GNSS receiver has been employed as term of comparison. Preliminary results suggest that SDR pseudorange are noisier than u-blox ones and this will probably reflect in the degradation of the single point solutions.
