Low-altitude monitoring device based on Beidou navigation technology

Abstract

The invention discloses a low-altitude monitoring device based on Beidou navigation technology, comprising a multi-communication link, an aircraft and a ground monitoring device, wherein the multi-communication link is mainly composed of a Beidou navigation and positioning satellite network, and a mobile communication network and an ADS-B data link supplemented; the aircraft respectively communicates with the Beidou satellite, the ground communication base station, and the ADS-B ground station through the multi-communication link; a high-definition camera and an infrared camera are disposed atboth ends of the carrier plate of the aircraft, a wireless communication device and an ADS-B transmitter are mounted on the carrier board, and a Beidou satellite positioning terminal is disposed above the carrier board; a Beidou receiving terminal, an ADS-B ground station, and a ground communication base station corresponding to the multi-communication link are installed at the receiving end of the ground monitoring device, and the ground monitoring device is connected with a user terminal through the communication network. The combination of a Beidou link, a mobile communication link, and anADS-B link is used to improve the accuracy of low-altitude monitoring.

Description

technical field [0001] The invention relates to the field of Beidou navigation, in particular to a low-altitude monitoring device based on Beidou navigation technology. Background technique [0002] The Beidou satellite navigation system is a global satellite positioning and communication system (BDS) developed by China itself. It is the third mature satellite navigation system after the US Global Positioning System (GPS) and Russia's GLONASS. The system consists of space terminals, ground terminals and users. Composed of terminals, it can provide high-precision, high-reliability positioning, navigation, and timing services for all kinds of users around the clock in the world, and has short message communication capabilities. It has initially possessed regional navigation, positioning, and timing capabilities. Positioning The accuracy is better than 20m, and the timing accuracy is better than 100ns. But in the prior art, most of the low-altitude monitoring equipments have t...
