The recently developed integrated Precise Point Positioning (PPP) GPS/INS system can be useful to many applications, such as UAV navigation systems, land vehicle/machine automation and mobile mapping systems. Since carrier phase measurements are the primary observables in PPP GPS, cycle slips, which often occur due to high dynamics, signal obstructions and(More)
“Time for space” was essential to the conventional algorithm of navigation and positioning by single satellite, but it will seriously affect the accuracy of single satellite in fast positioning. Based on the analysis of the principle of traditional single satellite location, in this paper, we briefly analyzed the advantages of single satellite(More)
