Three-Dimensional Convex Hull Satellites Selection Algorithm: Considering the Quality of Observations for Multi-GNSS Precise Point Positioning
Abstract Based on the geometrical layout of satellite constellation, a three-dimensional convex hull satellites selection algorithm for multi-GNSS precise point positioning is constructed. In order to further improve the positioning performance of multi-GNSS PPP, we propose the idea of three-dimensional convex hull satellites selection algorithm considering the quality of observations. Finally, the selection effect and positioning performance of the proposed algorithms are verified and analyzed by employing the measured data.
