A novel Stop&Go GPS precise point positioning (PPP) method and its application in geophysical exploration and prospecting

Abstract A new method of Stop&Go positioning method based on PPP is proposed in this paper with an application to geophysical exploration and prospecting. The method couples the kinematic PPP and static PPP, where the continuous kinematic observations between two sequential short static observations provide a correction for the carrier phase ambiguities. Therefore, the whole consecutive observations, including both static and kinematic segments, will contribute to the ambiguities convergence of each point with few epochs’ static observation. The experimental results showed that for the measured points which are observed over 60 s with 5 s sampling rate in static mode, the positioning accuracy can reach 5–6 cm in the horizontal and 0·1 m in the vertical; for those points which are observed over 10 s with 5 s sampling rate in static mode, the positioning accuracy is about 8–9 cm in horizontal and 0·12 m in vertical.
