GPS satellite pre-positioning device and method for mechanical vehicles

Abstract

The invention provides a GPS (global position system) satellite prepositioning device and method for machinery vehicles and relates to the field of GPS positioning. The vehicle position subjected to first time preset is prepositioned according to current speed information, current position coordinates, pre-input route information and presumptive driving speed information of the next section, and a prepositioning coordinate result is generated; since the current speed information ,the current position coordinates, the presumptive driving speed information of the next section are quite accurate and the other decision condition of preposition is the pre-input route information, driving direction of the vehicle is determined, the pre-positioning coordinate result generated according to the current speed information, the current position coordinates, the pre-input route information and the presumptive driving speed information of the next station is quite accurate, and fitness of the prepositioning coordinate result and the actual position of the vehicle is quite high.

Description

technical field [0001] The invention relates to the field of GPS positioning, in particular to a GPS satellite pre-positioning device and method for a mechanical vehicle. Background technique [0002] With the development of people's living standards, cars have entered the lives of thousands of households. With the development of science and technology, people have installed GPS locators on cars to facilitate the specific location of vehicles on the terminal. The GPS locator is a terminal with a built-in GPS module and a mobile communication module, which is used to transmit the positioning data obtained by the GPS module to a server on the Internet through the mobile communication module (gsm / gprs network), so that it can be realized on a computer or Query the location of the terminal on the mobile phone. However, in the actual positioning process using the GPS locator, because the car may be driving, the mobile communication signal of some road sections is weak or the mob...

AI Technical Summary

Problems solved by technology

However, in the actual positioning process using the GPS locator, due to the fact that the mobile communication signal of some road sections is weak or the mobile signal is blocked (for example, when the car is driving) The specific location of the vehicle is transmitted to the remote intelligent terminal in real time, or there is a large error in the real-time location of the vehicle sent, which makes the remote intelligent terminal unable to pay attention to the current location of the vehicle in real time or the error of the current location of the vehicle is large
