In Precise Point Positioning (PPP), error sources at and above cm-levelhave to be either corrected or modeled. An experiment is performed in this paper with a single receiver to observe the phase wind-up effect by changing the relative orientation of the receiver antenna. Moreover, traditional PPP is extended by including a subset of code multipath delays in the state vector. Thus, the station coordinates...
A key prerequisite for Precise Point Positioning (PPP) with Global Navigation Satellite Systems (GNSS) is the precise knowledge of satellite phase and code biases. This paper proposes a method, that is based on a very general measurement model with an individual phase and code bias for each receiver, satellite and frequency. We compute a recursive least-squares float solution with a Kalman filter,...
