Problems solved by technology

This solution can solve the drift problem in a static state to a certain extent, but it is only realized by judging whether the speed is less than a speed threshold. Judging whether drift occurs through acceleration solves the drift problem in a moving state

Abstract

The invention provides a method and equipment for inhibiting GPS drift in a vehicle stationary state and relates to the positioning technology field. The method comprises steps that the vehicle position information sent by a satellite positioning system is acquired in real time when a vehicle is in a stationary state, and the position information comprises the time and latitude and longitude coordinates corresponding to the time; the parameter information of the vehicle is determined according to the position information, and the parameter information comprises a speed value, an acceleration speed and a direction difference value; the preset parameter information is acquired, and the preset parameter information comprises a preset speed value, a preset acceleration speed and a preset direction difference value; and the position information is screened according to the parameter information and the preset parameter information. The method is advantaged in that positioning drift inhibition of the vehicle in the stationary state can be realized.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a technology for suppressing positioning drift, specifically a method and device for suppressing GPS drift in a stationary state of a vehicle. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The current satellite positioning systems all have the problem of positioning drift. The so-called drift means that there is a large error between the position obtained through the satellite positioning system and the actual position of the navigation terminal, which has exceeded the accuracy range of the positioning system. There are many reasons for the drift. For example, the radio wave signal of the satellite is affected by the weather, or it is refracted by tall building...
