Abstract
A space navigation receiver (NR) comprises i) a radiofrequency processing module (PM) tasked both with converting radio navigation signals transmitted by a satellite navigation system into digital navigation signals, and with converting auxiliary radio signals representative of navigation information about said system into auxiliary digital signals, ii) a digital processing module (PM) tasked with periodically acquiring the digital navigation signals by sub-sampling the received radio signal, then processing the acquired signal samples (resulting from this sub-sampling) in order to produce raw measurements from these samples, from auxiliary digital signals, and from location points, and iii) a location module (LM) tasked with determining location points based on raw measurements, demodulated navigation data initially contained within the digital navigation signals in a modulated form, and orbital force models.
