摘要: 随着全球卫星导航系统的快速发展,对航空安全提出了挑战,完好性监测问题愈发凸显,用户端自主完好性监测是研究的重点之一。针对用户端自主完好性监测问题,介绍了所需导航性能的四个重要参数,包括精度、完好性、连续性和可用性。从单卫星故障下的用户端自主完好性监测、多卫星故障下的用户端自主完好性监测、高斯噪声下的用户端自主完好性监测三个方面,综述了国内外相关的重要研究,主要涉及了三个层次内容:算法、计算保护限值和可用性,并指出了目前研究存在的不足。介绍了近期研究的新趋势与取得的成果。最后,展望了未来的研究方向。

Abstract: With the development of global navigation satellite system, the safety of civil aviation is a new challenge to face, and the integrity monitoring problems become more prominent. The receiver autonomous integrity motoring is one of important research. For receiver autonomous integrity motoring, the system must provide the required navigation performance for civil aviation, specified in terms of the four parameters of accuracy, integrity, continuity and availability. The recent developments in related fields were reviewed, including receiver autonomous integrity motoring under single and multiply satellite failure at a time, and under Gaussian noise environment, especially involving the algorithm, the protection limit and the availability. And then the shortcomings of the research were pointing out. In addition, the new trends and the recent research results were introduced. Moreover, the future research direction were prospected.
