Abstract
A GNSS receiver, and an associated method are presented for calculating a position from positioning signals transmitted by a plurality of GNSS transmitters. For example the receiver compsises a first and a second signal acquisition elements having different polarizations, the receiver being configured to process the signals received on the first signal acquisition element to calculate first pseudo range measurements, and the signals received on the second signal acquisition element to calculate second pseudo range measurements and associated quality indicators. The receiver further comprises a calculation circuit configured to select at least one of the second pseudo range measurements depending on the quality indicators, and compare it with the corresponding first pseudo range measurement, and select at least three first pseudo range measurements based on the comparison results to calculate a position.
