Abstract

The invention provides an integrated navigation integrity monitoring system for unmanned aerial vehicles, including: an inertial measurement device, used to provide the zero bias value of inertial measurement devices of different levels to the processor; a receiver, used to receive global satellite navigation signal, and provide the integrity risk of the global satellite navigation system to the processor; the processor is used to calculate the horizontal protection level of the integrated navigation and the vertical protection level of the integrated navigation; set the horizontal warning limit and the vertical warning limit, and the calculated The horizontal protection level and the vertical protection level are compared with the corresponding horizontal warning limit and vertical warning limit respectively to monitor the integrity of the UAV. The present invention does not need hardware redundancy to realize the inertial navigation system, which can reduce the integrated navigation integrity monitoring. the cost of.

Description

technical field [0001] The invention relates to the technical field of aviation navigation, in particular to an integrated navigation integrity monitoring system for unmanned aerial vehicles. Background technique [0002] With the application of UAV (Unmanned Aerial Vehicle, UAV) in the civilian field more and more widely, it brings many conveniences to people's work and life, such as agricultural plant protection UAV, aerial photography UAV, etc., but at the same time It has brought many safety hazards, such as the frequent occurrence of "black flying" incidents, flying in crowded places and airports, etc., which have brought many troubles to the production and life of the society. How to effectively realize the safe flight of UAV in the controlled airspace is a practical problem in the current application of UAV in the civilian field. Safety measures to ensure the flight of UAVs in specific areas, to ensure the safety of operations, and to achieve safe and effective fligh...
