Method and system for compensating inability of positioning, tracking and navigation of GPS system

Abstract

The invention relates to a method which makes up the GPS system not to orientate, track and navigate, including the following steps: (1) normally orientating, tracking and navigating of the GPS system; (2) detecting the GPS system whether to accept the ample satellite signals, if so, going to executing the step (1), if not going to the step (2); (3) recoding the present position, the speed information, starting the speed sensor working system; (4) continuously transmitting the measured acceleration to the data processing part by the speed sensor, wherein the data processing part computes the position and the speed and transmits to the UI and display to the users according to the acceleration, the position and the speed information; (5) detecting the size of the satellite signal, if satisfying the requirement then executing the step (6), if not going on to the step (4); (6) invocating the GPS system to orientate, track and navigate, closing the speed sensor. The invention uses the speed sensor to make the defect of the GPS system not to orientate, track and navigate, and the perfect system is formed by the GPS system and the speed sensor.

Description

Technical field [0001] The invention relates to a GPS system, in particular to a method and a system for making up for the gap when the GPS system cannot locate, track and navigate. Background technique [0002] The GPS system is an intelligent positioning, tracking and navigation system that has developed rapidly in recent years. It uses multiple satellites to form a network to track, locate or navigate equipment that has signal receiving on the ground. This is good information for vehicles such as cars, and it can help vehicles equipped with GPS devices in a moving state to better identify road information. In addition, these objects equipped with GPS devices can be located or tracked. [0003] However, as an accurate positioning, tracking and navigation system, the GPS system has shortcomings such as weak signal capability and susceptibility to interference. Once the signal cannot be received effectively, the GPS system is in an invalid working state. If the GPS device cannot ...

AI Technical Summary

Problems solved by technology

Some artificial buildings will become the signal dead spots of the GPS system 2, which will affect the effect of the GPS satellite positioning system

Once the vehicle with GPS device 1 enters these signal dead spots 2, it will lose satellite information and cannot continue positioning, tracking, navigation, etc., such as figure 1 as shown, figure 1 It is a schematic diagram of positioning, tracking and navigation that cannot be realized by using the GPS system in the prior art

Vehicles that rely on GPS system navigation will fall into a state of confusion, making it difficult for drivers to effectively judge the direction and speed of driving
