Multi-mode positioning module based on satellite positioning

Abstract

The invention discloses a multi-module position module based on the satellite position, which comprises a GPS OEM board with up-and -down structure and a DR circuit plate, wherein the two parts are connected with each other by the interface; the multi-module position module also possesses a position beacon interface, a matching electric map interface, an angle speed measuring unit, a car mileage and reverse signal matching receiving circuit, a MCU CPU, a computer communication interface and a power managing module.

Description

technical field [0001] The invention relates to a communication module, in particular to a multi-mode positioning module based on satellite positioning. Background technique [0002] In modern vehicle satellite navigation and positioning technology, satellite positioning technology is widely used, such as the global positioning system (GPS) of the United States, GLONASS of Russia, and Beidou positioning system of China; Loaded with a GPS receiver, if you can ensure good reception of 4 satellite signals, you can accurately know the vehicle's position, speed, direction of movement and other elements; but in practical applications, due to metropolitan viaducts, tunnels, overpasses and other reasons, many areas Satellite signals cannot be received; moreover, due to the multi-channel effect of radio waves brought by large urban buildings, the positioning accuracy of GPS is greatly reduced; in jungle areas or cities with tall trees, due to the influence of leaves on radio waves, i...

[0002] In modern vehicle satellite navigation and positioning technology, satellite positioning technology is widely used, such as the global positioning system (GPS) of the United States, GLONASS of Russia, and Beidou positioning system of China; Loaded with a GPS receiver, if you can ensure good reception of 4 satellite signals, you can accurately know the vehicle's position, speed, direction of movement and other elements; but in practical applications, due to metropolitan viaducts, tunnels, overpasses and other reasons, many areas Satellite signals cannot be received; moreover, due to the multi-channel effect of radio waves brought by large urban buildings, the positioning accuracy of GPS is greatly reduced; in jungle areas or cities with tall trees, due to the influence of leaves on radio waves, in rainy days, GPS The positioning is unreliable; the consequence of this is that continuous and accurate vehicle positioning cannot be provided, which affects the use of satellite navigation systems; in the market, many companies provide standard GPS positioning modules; the GPS positioning module is just a circuit board, without a shell and Ordinary user interface, mainly used by GPS receivers and system integration manufacturers
