Abstract

The embodiment of the present application discloses a GNSS-based differential positioning method, device, equipment and storage medium. The method includes: in the i-time positioning process, receiving the difference information corresponding to the first VRS sent by the data center, i is a positive integer; storing the difference information corresponding to the first VRS; in the i+k time positioning process, Judging whether the differential information multiplexing condition is satisfied, k is a positive integer; if it is determined that the differential information multiplexing condition is satisfied, then obtain the stored differential information corresponding to the first VRS; perform differential positioning according to the differential information corresponding to the first VRS. On the one hand, the embodiment of the present application reduces the calculation and processing overhead of the data center, and on the other hand, reduces the transmission load between the data center and the terminal, so that when the data center serves many terminals, it is less likely to be congested, and further The real-time positioning of the terminal is guaranteed.

Description

technical field [0001] The embodiments of the present application relate to the technical field of positioning, and in particular to a GNSS (Global Navigation Satellite System, Global Navigation Satellite System)-based differential positioning method, device, device, and storage medium. Background technique [0002] GNSS differential positioning technology uses CORS (Continuously Operating Reference Stations, Continuously Operating Reference Stations) with known coordinates to receive satellite signals synchronously with the terminal, and considers that the terminal and its nearby CORS have the same error, and eliminates the error through differential. [0003] In order to obtain higher positioning accuracy, multiple CORS are usually used for differential positioning. This technology for performing differential positioning based on multiple CORS is also referred to as a VRS (Virtual Reference Stations, virtual reference station) differential positioning technology. The impl...
