Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0015] A low-cost UAV anti-trap navigation system includes a satellite positioning system, an inertial navigation system, and an information comprehensive processing module.

[0016] The inertial navigation system is a system that uses gyroscopes and accelerometers installed on the vehicle to determine the position of the vehicle. Through the measurement data of the gyroscope and the accelerometer, the movement of the vehicle in the inertial reference frame can be ...

Abstract

The invention relates to the technical field of drone anti-trap measures, and particularly discloses a low-cost drone anti-trap navigation system. The low-cost drone anti-trap navigation system comprises a satellite locating system and an inertial navigation system, and the satellite locating system can receive navigation signals of multiple frequency points of multiple satellite navigation systems (a Beidou and a GPS) to enable the functions of navigation telegraph text demodulation, measurement value extraction and the like and has a timing function; according to index requirements of the measurement precision, the range, the encapsulating performance, the impact resistance, the temperature drift and the like, the inertial navigation system completes style selection of an MEMS sensor; the inertial system is built to achieve a strapdown solving information comprehensive processing module of the posture, the position and the speed, wherein a telegraph text and measurement data of a navigation satellite are processed, detecting and removing false interference signals are achieved, and a normal navigation function of a drone is enabled. The low-cost drone anti-trap navigation systemhas the advantages that the navigation system with the anti-trap function is applied to the drone, a 'firewall' is formed for the drone with a police purpose, security safeguard, security protection and transportation surveillance, so that law breakers have no opportunity to take advantage of.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle anti-entrapment technology, in particular to a low-cost anti-entrapment navigation system for unmanned aerial vehicles. Background technique [0002] In recent years, the blowout development of the UAV industry has affected the normal aviation flight. In response to the increasingly complicated UAV market, many companies have launched UAV traps, which can make UAVs fly or make forced landings according to their desired routes by interfering with UAV navigation systems or providing false navigation signals. However, if these drone traps are in the hands of some illegal legal persons, they will interfere with drones performing police, security, security, and traffic surveillance tasks. In response to this situation, we have developed an anti-interference and anti-trap drone navigation system for professional drones such as police and security, so that police and security drones will not be in...
