Abstract The Advanced Receiver Autonomous Integrity Monitoring (ARAIM) provides an Aircraft‐Based Augmentation System function for aircraft Global Navigation Satellite equipment. Currently, the consideration of temporal correlations test statistics is important update to ARAIM baseline algorithm. However, due tight budgets integrity and continuity, updated Fault Detection Exclusion (FDE) not satisfactory in availability coverage. algorithm based on equal allocation which causes be...
The integrity risk requirements proposed by the ICAO for GNSS aviation applications in different operation stages are difficult to directly apply a snapshot ARAIM user algorithm directly. To reduce conservativeness introduced process of mapping, paper proposes method allocate requirement over an exposure time. A strict definition time is introduced. functional relationship between period and protection levels each epoch derived based on first-order Gauss–Markov process. real-time level...
The integrity risk requirements proposed by the International Civil Aviation Organization (ICAO) for GNSS aviation applications in different operation stages are difficult to directly apply a snapshot Advanced Receiver Autonomous Integrity Monitoring (ARAIM) user algorithm. To reduce conservativeness introduced mapping process, paper proposes method allocate requirement over an exposure time and assess availability. Strict definitions of ARAIM continuity introduced. functional relationship...
The Ground-Based Augmentation System (GBAS) is a navigation system for aircraft designed to be used precision approaches and landings. GBAS improves the accuracy of satellite significantly. However, some flight accidents still occur occasionally due lack availability it makes more stringent requirements on that CAT II/III precise approach trying introduce GBAS. Therefore, necessary find an effective prediction algorithm protection level key parameter in process evaluating availability. There...
With the increasing traffic volume of airport, ensuring safe and effective operation airport has become one major challenges in field civil aviation. The real-time positioning is worthwhile devoting much effort. paper proposes a method Beidou Navigation Satellite System (BDS) Aeronautical Mobile Airport Communications (AeroMACS) integrated for surface surveillance, based on experimental scene at Hehua Airport. Compared with original GNSS method, algorithm can effectively solve problem that...
