Beidou positioning system-based positioning method

Abstract

The invention discloses a Beidou positioning system-based positioning method. The method comprises the following steps: initializing a central control module; judging information fed back by an antenna to determine whether the touch with a satellite is lost; calling a track prediction method by the central control module to judge the track of the satellite and then calculating positioning information if the touch with the satellite is lost; receiving a satellite signal by Beidou double antennas if the touch with the satellite is not lost, and transmitting the obtained satellite signal to a radio frequency receiving module, filtering the satellite signal by the radio frequency receiving module, amplifying the signal and then transmitting to the central control module, and calculating the positioning information by the central control module through the acquired data information; transmitting the calculated positioning information to a storage management module by the central control module, calling map information of the storage module by the storage management module, and combining the map information with the positioning information and then displaying on a display module.

Description

technical field [0001] The invention discloses a positioning method based on a Beidou positioning system, and belongs to the technical field of signal processing. Background technique [0002] The Beidou positioning system is a global positioning system independently developed by my country. At present, the Beidou positioning system has 16 satellites in orbit. As of December 27, 2012, the official version of my country's Beidou positioning system space signal interface control document has been released. The navigation business officially provides passive positioning, navigation and timing services to the Asia-Pacific region. The system can provide positioning services for common vehicles such as automobiles, airliners and ships, and provide positioning and navigation services for precision-guided weapons. It is of great significance for my country's military and national defense to get rid of dependence on foreign GPS systems. also has important meaning. [0003] The patent...

Problems solved by technology

[0003] The patent number is CN103869347A, and the patent name is a Beidou satellite navigation and positioning system. This patent improves the positioning speed and accuracy in the prior art, and improves the coverage and anti-interference ability of the positioning system. However, the patent does not have remote control And remote data transmission function, without its own data processing system, can not promptly and quickly notify the remote situation

[0004] The patent number is CN104105066A, and the patent name is a communication system based on Beidou satellite. This patent points out the shortcomings of the complex and unstable positioning system in the prior art, and also provides a certain solution, but the solution is too idealized and does not give specific implementation techniques

[0005] At the same time, the commonly used signal conditioning circuits in the prior art generally have the problems of complex structure and high power consumption, which need further improvement
