Stability Analysis of Satellite Navigation and Positioning Reference Stations Considering Linear Motion

Abstract

Abstract The coordinate frame is not only the foundation for depicting the shape and changes of the Earth and expressing geospatial information but also the crucial geospatial information infrastructure for expanding human activities and promoting social development. Research on satellite navigation and positioning reference stations considering linear motion will be of great significance for navigation and positioning. Therefore, this paper first deduces the transformation formula between different international terrestrial reference frames (ITRF) and the transformation relationship between different reference epochs. Second, a comparison experiment is conducted to analyze the influence of coordinates under different reference frames and epochs on the accuracy of the international GNSS service (IGS) baseline solution results. Finally, stability analysis is performed considering the effect of linear motion on the urban frame points. The results show that using the coordinates under the reference frame and epochs that best fit the measurement time for the baseline solution gives the most reliable results.
