全球卫星导航系统(GNSS,Global Navigation Satellite System)由于能够实时为用户提供时间,经纬度和海拔高度等导航信息,在军事、通讯和测量等领域已得到广泛的应用,因此研究GNSS软件接收机的设计与关键技术具有重要应用价值。从GNSS接收机算法验证与测试的需求出发,设计了一种基于软件实现的GNSS接收机算法验证平台,重点研究了与该验证平台实现相关的高动态卫星导航信号捕获方法、跟踪、测量值预处理方法和接收机自体完好性监控(RAIM,Receiver Autonomous IntegrityMonitoring)方法等关键技术。实际结果表明实现的GNSS软件接收机算法验证平台具有算法验证灵活,可重构性好、定位精度高等特点,可以为各种GNSS接收机算法的测试与验证提供参考。
The Global Navigation Satellite System (GNSS) has been widely used in military, communication and measurement fields due to its ability to provide users with navigation information such as time, latitude, longitude and altitude in real time. Therefore, the design of the GNSS software receiver And the key technology has important application value. Based on the requirement of GNSS receiver algorithm verification and test, a GNSS receiver algorithm verification platform based on software is designed. The method to capture high-dynamic satellite navigation signals related to the verification platform is studied. The tracking, Processing methods and Receiver Autonomous Integrity Monitoring (RAIM) methods. The actual results show that the GNSS software receiver verification platform has the advantages of flexible algorithm verification, good reconfigurability and high positioning accuracy, which can provide reference for the testing and verification of various GNSS receiver algorithms.
