Perception type satellite positioning device and method

Abstract

The invention discloses a perception type satellite positioning device and a perception type satellite positioning method. The device is arranged on a carrying device and is used for receiving positioning data sent by a satellite so as to determine the action state of the carrying device and correct errors of positioning data of the carrying device, and comprises a sensing module, a database, an analysis module and a correction module, wherein the sensing module is used for receiving the positioning data, which is sent by the satellite, of the carrying device; the database is used for storing the positioning data received by the sensing module and presetting an action conversion array of the carrying device; the analysis module is used for analyzing the positioning data and the action conversion array to acquire prediction action data of the carrying device; and the correction module is used for comparing the prediction action data of the carrying device with the positioning data to correct the errors of the positioning data of the carrying device. Therefore, the problem of insufficiently accurate positioning data of a commonly-known satellite positioning device can be solved.

Description

technical field [0001] The present invention relates to a perceptual satellite positioning device and its method, more specifically, to a satellite positioning device for positioning a vehicle and its method. Background technique [0002] Known navigation technology can provide a vehicle for positioning. Although scholars are committed to the research of various navigation technologies, these navigation technologies still have certain defects. For example, the disadvantage of terrain navigation (Pilotage) is that it is easy to cause navigation errors due to wrong landmarks. The disadvantage of dead reckoning navigation is that the error accumulation will become larger and larger when the navigation time is prolonged. Celestial navigation (Celestial navigation) The position of the star is used for angle measurement and positioning. The distance between the star and the measurement vehicle is very far, so that a very small angle measurement error will produce a large position...

Problems solved by technology

[0004] Therefore, how to find out a device and method that can perform behavior prediction and positioning correction on the vehicle, so as to avoid the problem of excessive drift error caused by the received positioning data (such as GPS positioning data) due to environmental influences, and at the same time, through the vehicle Behavior prediction can improve the accuracy of positioning data and avoid problems such as positioning errors caused by cumulative errors in known methods. This is an urgent technical issue to be solved at present
