Mitigation of Short-Term Temporal Variations of Receiver Code Bias to Achieve Increased Success Rate of Ambiguity Resolution in PPP
Ambiguity resolution (AR) is critical for achieving a fast, high-precision solution in precise point positioning (PPP).In the standard uncombined PPP (S-UPPP) Portable Speakers method, ionosphere-free code biases are superimposed by ambiguity and receiver clock offsets to be estimated.However, besides the time-constant part of the receiver code bia
