The invention provides a performance test method, device and system for a foundation enhancement system. The method comprises: continuously acquiring GNSS satellite data and VDB data; respectively calculating a differential positioning result, a positioning error result and a protection level result according to the GNSS satellite data and the VDB data, and recording the results as monitoring calculation process data; analyzing the GNSS satellite data, the VDB data and the monitoring calculation process data; and according to the generated readable GNSS satellite data, the readable VDB data and the readable monitoring calculation process data, calculating each performance index test value of the foundation enhancement system. By applying the method, various properties including accuracy, continuity, usability and integrity of the tested foundation enhancement system can be calculated and evaluated, test support services are provided for airworthiness evidence collection and normal operation of the foundation enhancement system, and potential safety hazards existing in flight safety are effectively eliminated.
Description
technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a performance testing method, device and system of a ground-based augmentation system. Background technique [0002] The ground-based augmentation system (English abbreviation: GBAS) is an important part of the satellite navigation system. Its working principle is to improve the accuracy of satellite navigation through differential positioning, and on this basis, an integrity monitoring algorithm is added to improve system integrity. Availability, continuity and other indicators enable aircraft with corresponding capabilities within the scope of action to obtain position signals that reach Class I precision approach or even higher precision, and then guide the aircraft to implement approach and landing flights. The ground-based augmentation system can meet the strict requirements of civil aviation precision approach and landing guidance on integrity, continuity and a...
