Abstract

The embodiment of the invention provides an auxiliary positioning method, device and equipment based on the position of a reference point, and the method comprises the steps: obtaining the observation data of a reference station network, generating a first auxiliary positioning model according to the observation data, obtaining the position information of the reference point, and matching the position information of the reference point with the first auxiliary positioning model to obtain a secondauxiliary positioning model, and sending the second auxiliary positioning model to the terminal equipment, so that the terminal equipment can carry out positioning error correction according to the second auxiliary positioning model. According to the embodiment of the invention, the user does not need to upload own position information, so that the position privacy of the user is protected while the effectiveness of the auxiliary positioning model of the user position is ensured, a communication unit and a satellite signal transceiving unit do not need to be deployed at a reference point at the same time, electromagnetic interference between a communication signal and a satellite signal is avoided, and the accuracy of the obtained auxiliary positioning model is ensured, so that the positioning accuracy of the terminal equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of high-precision positioning, and in particular relates to an auxiliary positioning method, device and equipment based on reference point positions. Background technique [0002] Satellite positioning technology means that the terminal calculates its coordinate position by receiving navigation signals broadcast by satellites. The accuracy of this positioning technology is affected by factors such as the ionosphere, troposphere, clock difference, etc. Auxiliary positioning systems are usually used to assist terminals in fast and accurate positioning. [0003] In the prior art, the base station equipment integrates a differential calculation unit and a mobile communication transmitting unit to calculate and transmit differential correction information. Wherein, the difference resolution unit receives and processes the satellite signals of the visible satellites, analyzes the measured pseudo-range values ​​fro...
