Beidou high-precision position service system based on CROS base station and application method

Abstract

The invention provides a Beidou high-precision position service system based on a CROS base station. The system comprises a service layer and a data persistence layer, the service layer is connected with the data persistence layer, and the service layer comprises a precision ephemeris downloading module, a base station gateway, a scheduling service module, a playing service module and a pluralityof resolving modules. The invention discloses the Beidou high-precision position service system based on the CROS base station. The scheduling service module is used for judging that a correspondingnumber of resolving modules need to be started according to original observation value data sent by the CROS base station; a previous mode of whole network difference of a single resolving module is changed into a mode of distributed resolving of a plurality of resolving modules; the resolving concentrated on the single server is distributed to a plurality of resolving modules for operation, so that the problem that part of servers cannot work due to software exception or external reasons can be solved, the resolving mode is not limited any more, and the resolving efficiency is greatly improved.

Description

technical field [0001] The invention relates to surveying and mapping, in particular to a Beidou high-precision location service system and application method based on a CROS reference station. Background technique [0002] When the application scenario is multiple different CROS reference stations, the calculation of the Beidou high-precision position needs to process the differential correction data of multiple CROS reference stations at the same time, and the amount of data processing is very huge. At present, for the data calculation in the application scenario of multiple CROS reference stations, only a single data processing system can be used to calculate the differential correction data. The calculation ability of this calculation method is limited. When there are a large number of reference stations such as the Internet and a large number of users obtain differential correction data at the same time, it is only possible to improve the hardware performance of the sta...
