Abstract

The invention discloses a method and a device for processing GPS positioning data. The method comprises steps: multiple position points of a target object acquired by a GPS terminal are acquired; the multiple position points are selected according to a preset selection rule, and the position points obtained through selection serve as effective position points to be added to a trusted list; the average speed of each effective position point in the trusted list is calculated; whether the average speed is a first preset speed is judged; if the average speed is the first preset speed, the average value of position parameters of all effective position points is acquired, and according to the average value of position parameters, a trusted position point is determined; if the average speed is not the first preset speed, the differences between the speeds of all effective position points and the average speed are acquired, and the effective position point corresponding to the speed with the minimal difference with the average speed serves as the trusted position point; and the trusted position point is reported. The technical problem of an inaccurate positioning result by a vehicle-mounted or handheld GPS terminal can be solved.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a method and device for processing GPS positioning data. Background technique [0002] GPS brings us a lot of convenience in real life, and its main function comes from its precise positioning. Whether it is a car navigator that guides us, or a handheld terminal that provides us with precise latitude and longitude to indicate the direction, and the practical application effect of GPS products in industry, logistics and even many industries, it has proved that GPS products The positioning accuracy is an important pillar for its wide application. [0003] Before analyzing the phenomenon of GPS positioning drift, we first understand how GPS achieves positioning based on satellite signals. GPS (Global Positioning System, Global Positioning System) includes three parts: space GPS satellite constellation, ground monitoring system, user GPS signal receiver. The basic prin...
