Problems solved by technology
However, the risk of manned flight test is extremely high. Due to the flight test of the Beidou satellite navigation system, the navigation performance of the Beidou satellite navigation system needs to be evaluated from the positioning accuracy and integrity. The operation is difficult and the risk factor is high
In addition, the use of manned aircraft for flight testing, the cost of testing is also very high

The invention relates to a Beidou satellite navigation system performance testing device based on an unmanned aerial vehicle. The Beidou satellite navigation system performance testing device comprises a ground differential station, the unmanned aerial vehicle and a Beidou satellite navigation receiver which are electrically connected in sequence. The unmanned aerial vehicle is provided with an unmanned aerial vehicle data link radio station, an airborne processor and a GPS satellite navigation receiver. The airborne processor is used for calculating GPS position information according to the GPS differential positioning data and the GPS satellite navigation signal; The airborne processor is also used for comparing the GPS position information with the Beidou satellite navigation position information and testing the performance of the Beidou satellite navigation system. The unmanned aerial vehicle is used for flight verification of the Beidou satellite navigation system, the flight cost is low, flight can be carried out strictly according to the longitude and latitude height of each waypoint, the temporary flight route change is simple, and the flight is safer.
Description
technical field [0001] The invention relates to the technical field of performance testing of the Beidou satellite navigation system, in particular to a performance testing device for the Beidou satellite navigation system based on an unmanned aerial vehicle. Background technique [0002] GNSS (Global Navigation Satellite System) has four evaluation parameters, Accuracy (navigation positioning accuracy), Integrity (integrity), Continuity (navigation service continuity) and Availability (navigation service availability). [0003] Navigation positioning accuracy is used to describe the coincidence degree of the position provided by the system for the user and the user's real position under a certain confidence probability (usually 95%). [0004] Integrity is related to the credibility of the services provided by the navigation system, and refers to the ability of the system to promptly report to the police within the specified time when the positioning error of the navigation ...
