Precise Point Positioning Based on Reference Stations Augmentation Information

Abstract

Abstract:

A new algorithm based on the regional reference stations network augmentation was proposed to realize Precise Point Positioning (PPP). Different from other methods, the presented strategy uses the Satellite-Differenced and Epoch-Differenced (SDED) technology. It removes the ambiguity and receiver clock parameters, and avoids the ambiguities converging or fixing. To weaken the influence of the residual tropospheric delay and potential biases, another new strategy is presented to deal with the Satellite and Epoch Differenced Biases (SEDB). Comparison to the normal PPP, the new method can improve the convergence and positioning accuracy, when less than 1500s data was processed.

Key words: Precise Point Positioning, Satellite and Epoch Differenced Bias(SEDB), Regional Augmentation, Reference Stations Network
