Network construction method of reference station triangle based on delaunay heterogeneous cors system

Abstract

The present invention relates to the network construction method of the reference station triangle based on Delaunay heterogeneous CORS system, comprising: step 1, setting up a triangle network, forming a Delaunay triangle in the triangle network; step 2, making the three reference stations form the Delaunay triangle The circumscribed circle coverage area of ​​the triangle is the largest while the sum of the side lengths is the smallest; Step 3, updating the real-time network dynamics of the reference site. The beneficial effects of the present invention are: the present invention innovates the hardware and software, network and data integration construction content of the heterogeneous CORS system: at the same time, it solves the different communication networks, different hardware and software, different operating systems, and different benchmarks of the heterogeneous CORS system The integration of station site selection, distribution of different reference stations, different network RTK positioning models and software, and different multi-center collaborative operations has achieved a high degree of sharing of heterogeneous CORS system hardware, software, network and data resources.

Description

technical field [0001] The invention belongs to the field of triangular networks of reference stations, and in particular relates to a construction and integration method of a triangular network of reference stations based on a Delaunay heterogeneous CORS system. Background technique [0002] If a unique triangulation network can be determined, the user only needs to select 3 reference stations in the triangular area where the rover is located, and establish a correction model covering this area with the observation information of the 3 reference stations. The advantage of the triangulation network is obvious. When the user is active in a triangular area, the base station and the baseline where the mobile station is located always maintain a strong correlation. When the rover measurement leaves this area , the system locks the measurement of the rover in the new triangle through the real-time selection of the triangle area, so that the maximum degree of coincidence between t...

Problems solved by technology

From the perspective of surveying and mapping management regulations and standards, these CORS cannot provide information and data public services to the society and the public

At present, the problem we need to study and solve as soon as possible is: according to the surveying and mapping laws and regulations, how to integrate the existing CORS resources in Hubei Province in a timely, active and conditional manner, and conduct unified administrative management of HBCORS to prevent repeated waste of resources

The construction of the above contents is far from meeting the needs of CORS system integration construction
