Abstract
With the acceleration of the global informatization process, the deep integration of satellite communication and global positioning system (GNSS) has become the key direction of the development of modern navigation technology. This study aims GPS based on satellite communication to explore its performance optimization and application expansion in complex environment. By combining advanced signal processing algorithm and multi-source data fusion technology, a new satellite communication enhanced positioning method is proposed, which can significantly improve the positioning accuracy and reduce the influence of signal interference. The study used simulation analysis and field test to verify the effectiveness of the proposed method in urban canyons and forest cover. The experimental results show that compared with the traditional GNSS system, the positioning error of the new method is reduced by about 30%, and it has stronger anti-interference capability. In addition, a real-time data transmission protocol suitable for low-orbit satellites was developed, which further improves the global coverage capability and response speed of the system.
