Abstract
ABSTRACT: This paper describes a carrier-phase–based precise point positioning (PPP) method based a new observation model. Unlike the traditional PPP processing method, the new method allows for exploitation of the integer characteristics of carrier-phase ambiguities. The new method also opens the door for the development of new algorithms for ambiguity resolution to support real-time PPP applications in the future. Numerical results indicate that the new method is superior to the traditional PPP processing method in terms of positional accuracy, convergence speed, and filter stability.
