Abstract

The invention belongs to the technical field of satellite positioning, and provides a satellite positioning data drifting restraining method and device. The satellite positioning data drifting restraining method includes the steps that an acceleration sensor is used for acquiring sensor data; the acquired sensor data are processed, and a judgment result whether satellite positioning data drifting is restrained or not is generated; according to the judgment result, current satellite positioning data are restrained, or according to the judgment result, the current satellite positioning data are reserved. The satellite positioning data drifting restraining method and device solve the problems that an existing satellite positioning data drifting restraining method needs to detect ACC signals all the time, the effectiveness of the satellite positioning data drifting cannot be accurately judged, and improvement of accuracy of the satellite positioning data drifting is not facilitated. Under the condition that the satellite positioning function is normally used, the ACC signals do not need to be processed, satellite positioning data drifting can be quickly restrained, the restraining accuracy of the satellite positioning data drifting is improved, and the restraining efficiency of the satellite positioning data drifting is improved.

Description

technical field

[0001] The invention belongs to the technical field of satellite positioning, in particular to a method and device for suppressing drift of satellite positioning data. Background technique

[0002] With the popularity of the positioning function, more and more vehicle monitoring systems are connected to the satellite positioning system to complete the positioning of the vehicle. At the same time, during the transmission process, the signal of the satellite positioning system will attenuate and interfere with the signal after passing through various complex environments such as weather, ground, and buildings, resulting in the deterioration of the accuracy of the satellite positioning information, that is, the occurrence of positioning errors. Accurate question. If the vehicle is in a stationary state, the satellite positioning information should be fixed in theory, but due to the above factors, the satellite positioning information in the vehicle monitoring s...
