Abstract

This paper will discuss the" Between-Satellite-Single-Difference" (BSSD) ionosphere-free linear combination of pseudoranges and carrier phase measurements from GNSS constellation namely "GPS, GALILIO and BeiDou". Inter system Biases will be removed from both code and phase. The using of BSSD technique can improve the precision of the latitude, longitude and altitude components, by comparison it with the traditional undifferenced technique the result show better positioning precision. This method will present an efficient model for precise point positioning (PPP).  BSSD "Between satellite signal difference" can cancel out the receiver hardware delay, receiver clock error, and the non-zero initial phase of the receiver will illustrate that the PPP solution will be improved by using our BSSD-based model in comparison with traditional undifferenced PPP model.
