Problems solved by technology

[0003] Existing multi-rotor drones use GPS navigation module alone for positioning, which has poor positioning accuracy and great limitations, and cannot meet the existing precise positioning requirements
On the other hand, the existing GPS navigation module used alone is susceptible to interference, resulting in fewer satellites received or lost satellites. The multi-rotor UAV will lose balance or land on the spot, resulting in personnel or property losses.

Abstract

The invention discloses a multi-rotor unmanned aerial plane navigation positioning system, comprising a ground positioning base station system, a ground measurement and control system and a multi-rotor unmanned aerial plane aircraft. The ground positioning base station system is used for sending difference positioning information; the ground measurement and control system receives the difference positioning information, combines the difference positioning information into remote control frames, and sends the remote control frames into the multi-rotor unmanned aerial plane aircraft; the multi-rotor unmanned aerial plane aircraft receives the remote control frames and utilizes the remote control frames to perform difference calculation to obtain positioning data; meanwhile, the positioning data is combined into remote control frames, and the remote control frames are sent to the measurement and control system to obtain high precision position information. The multi-rotor unmanned aerial plane navigation positioning system can meet multi-task requirements on accurate positioning, possess a stronger anti-interference capability, and solve the disadvantages of large positioning measurement errors and susceptibility to interference of present test systems.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle navigation and positioning system. Background technique [0002] The multi-rotor unmanned aerial vehicle is a new type of rotorcraft. It has multiple rotors that are symmetrically distributed around the body and rotates in pairs. It is a miniature aircraft with vertical take-off and landing, stable hovering and autonomous cruise capabilities. It has broad application prospects in military and military fields. This type of aircraft is generally driven by electric energy, and has the characteristics of simple structure, stable flight, easy control (cooperating with the flight control system), low noise and no pollution, easy to carry, and low safety hazards. In recent years, multi-rotor unmanned aerial vehicles have gradually attracted great attention at home and abroad, and some typical products have been born one after another. [00...
