| Abstract: | The rapid development of the global satellite navigation systems poses a new challenge to the safety of civil aviation, and integrity monitoring becomes a more prominent problem. Receiver autonomous integrity motoring (RAIM) is one focus of research, for which the system must provide the required navigation performance for civil aviation specified in terms of the four parameters of accuracy, integrity, availability and continuity. Recent developments in related fields are reviewed, including RAIM with single and multiple satellite failures, and under Gaussian noise environment. The review especially involves the monitoring algorithm, the protection limit and availability, and then points out shortcomings of present research. In addition, new trends and recent research results are introduced. Finally, future research directions are examined. |
