Abstract
Base stations of a satellite navigation system have receivers Phase biases and instrumental and atmospheric errors, are determined and transmitted to navigation devices. Precise Point Positioning includes steps of: obtaining code and phase measurements which were performed on the satellite signals by the plurality of receivers at two or more frequencies, determining separate individual values for a plurality of phase ambiguities and a plurality of the errors based on the code and phase measurements, wherein the receivers are grouped into clusters, and in each cluster a determination of a single cluster solution is performed, in which satellite errors selected from the group of satellite position errors, satellite clock errors and satellite phase biases are determined based on the phase and code measurements performed by the receivers of the respective cluster; and a multi-cluster solution is performed, in which the single cluster solutions are adjusted.
