Abstract

The invention is suitable for the technical field of satellite positioning, and provides an allocation method and system of a network RTK (Real Time Kinematic) service, a cloud server and a memory. The method comprises the following steps: connecting base stations distributed throughout the country into a network structure, wherein the network structure comprises a geometric element combination, and the geometric element combination at least includes triangular elements; dividing the network RTK service into corresponding sub-tasks based on the geometric element combination; and calculating computing resources needing to be consumed by the corresponding sub-tasks, and performing service allocation based on a computing result. In the allocation method, all the base stations throughout the country are connected into the network structure, service allocation is performed on the basis of the network structure, and one big task is allocated to a plurality of computers, so that the problem of concurrence of a large scale of network RTK services is solved.

Description

technical field [0001] The invention belongs to the technical field of satellite positioning, and in particular relates to a network RTK service distribution method and system, a cloud server, and a memory. Background technique [0002] Network RTK (Real Time Kinematic) technology uses a GNSS network composed of multiple base stations to provide correction data for rover stations within the coverage area, enabling high-precision positioning. [0003] The existing network RTK system is divided into different modules, and different modules are compiled into independent software, which are deployed on multiple servers and run on multiple servers. Multiple servers complete data interaction in the same local area network, providing all users with access services Provide real-time differential data services. [0004] For example, a network RTK system includes a base station (including a base station data receiving and management module), a data control center (including a GNSS da...
