Abstract
The invention relates to a Global Navigation Satellite System (GNSS) receiver, comprising 1) a radiofrequency (RF) front-end configured to acquire GNSS signals emitted by a plurality of GNSS satellites in at least two snapshot time windows, wherein each emitted GNSS signal comprises a respective known spreading code identifying the emitting GNSS satellite, and wherein the RF front-end is configured to transform the acquired GNSS signals in each of the at least two snapshot time windows into a digital sequence, respectively, and 2) a receiver unit configured to determine for each snapshot time window pseudo-ranges from the GNSS receiver to at least a subset of the emitting GNSS satellites, respectively, wherein said at least two subsets corresponding to the at least two snapshot time windows may differ from one another, and wherein said pseudo-ranges are determined using (i) the known spreading codes and (ii) the at least two digital sequences. The GNSS receiver is configured to determine composite pseudo-ranges between the GNSS receiver and a composite subset of the emitting GNSS satellites at composite receive times, using at least the determined pseudo-ranges corresponding to the at least two snapshot time windows. The invention also relates to an assembly comprising a GNSS receiver, a gateway and a computing unit. The invention also relates to a method for determining a position of a GNSS receiver.
