Abstract

The invention discloses a GNSS-based data real-time processing method and system and a storage medium, and the method comprises the following steps: S1, monitoring the resource use condition of a data server in real time, and dynamically distributing and releasing resources; s2, starting a plurality of data access instances according to the number and configuration of the accessed base stations, and distributing the base stations to the data access instances; s3, the data access middleware summarizes the processing results of the multiple data access instances and starts multiple data preprocessing instances according to the data volume, and a data queue summarized by the data access middleware is preprocessed; and S4, the data result middleware summarizes the results of the plurality of data preprocessing instances to an epoch information queue. By adopting the data real-time processing method, data access and data preprocessing are separated, and a plurality of data access instances and a plurality of data preprocessing instances are arranged, so that the data of a plurality of base stations can be synchronously processed, the data processing efficiency is improved, and real-time processing of a large amount of satellite data becomes possible.

Description

technical field [0001] The invention relates to the technical field of satellite data processing, in particular to a GNSS-based real-time data processing method, system and storage medium. Background technique [0002] GNSS (Global Navigation Satellite System, Global Navigation Satellite System) high-precision positioning base station is used to receive satellite broadcast data at a fixed point, and combine the basic information of the base station itself to broadcast a positioning data stream based on the GNSS system. After solving, high-precision positioning services can be provided for specific terminal devices. [0003] GNSS high-precision positioning base station data stream, as the source of data, its integrity and reliability are the basis for determining the ability to provide effective high-precision positioning services. The current integrity verification method is mostly to accumulate and save the original base station data stream. After parsing into plaintext RI...
