Abstract

The invention discloses a remote supercomputing method for GNSS data, which comprises the following steps: S1: collect GNSS original data, pack it, and store it in memory; S2: decrypt and analyze the GNSS original data in memory, and The GNSS data obtained after decryption and analysis is completed and stored in the database; S3: Call the decrypted and analyzed GNSS data, perform core calculations, obtain the final solution data, and store the final solution data in the database; S4: Through the computer client or The mobile phone accesses the server to obtain the final solution data or GNSS raw data, and performs single-server deployment, multi-server deployment or cloud service deployment according to the number of users and GNSS data volume, and completes remote overcomputing of GNSS data. The supercomputing method of the present invention is compatible with GNSS data formats of all manufacturers and all types of Cors reference system data, and supports conversion between different GNSS data formats.

Description

technical field [0001] The invention belongs to the technical field of GNSS data processing, and in particular relates to a remote supercomputing method for GNSS data. Background technique [0002] In the field of high-precision location services, it is mainly realized by relying on the global navigation satellite system (GNSS) technology. By establishing a satellite navigation and positioning reference station system (continuously operating reference stations, CORS) to observe GNSS satellite information in real time and continuously, it can quickly Effectively weaken the main error effects of orbit, clock error and atmosphere, so as to achieve real-time centimeter-level and post-event millimeter-level precision positioning. GNSS-based deformation monitoring, surveying and mapping navigation, tracking and positioning, etc. all have a great demand for high-precision level (millimeter level) location services. General units do not have the service conditions, the main reasons...
