Description

Technical Field

[0001] The present invention relates to the field of satellite positioning, and particularly to a method, a server, and a client for displaying the solution quality of a CORS triangular network. Background Art

[0002] The Global Navigation Satellite System (GNSS) realizes positioning through satellite signals. However, affected by errors such as ionospheric delay, tropospheric refraction, and satellite clock offset, the single-point positioning accuracy is usually only at the meter level. To break through the accuracy limit, the differential GNSS technology emerged. By calculating error correction numbers at a fixed reference station and broadcasting them to users, the positioning accuracy is improved to the centimeter level. As an advanced form of differential GNSS technology, the Continuous Operating Reference Station System (CORS) forms a real-time differential service system with a wider coverage and more stable accuracy by deploying multiple permanent reference stations (forming a triangular network distribution) in a region, and has become the infrastructure for modern high-precision positioning. The CORS triangular network is a GNSS triangular network based on CORS reference stations, specifically referring to a network control structure formed by connecting 3 or more CORS reference stations through baseline vectors. Different from the traditional GNSS triangular network (formed by temporarily deployed reference stations), the CORS triangular network has the characteristics of permanence, networking, and real-time. Its reference stations are usually fixedly installed on stable bedrock or buildings, continuously observe satellite signals for 24 hours, and transmit data to the data center in real time through a dedicated network (such as optical fiber and 4G) for centralized solution, and finally provide real-time differential correction services to users.

[0003] After the CORS triangular network solution is completed, under normal circumstances, the real-time common satellite number participating in the triangular network and its baseline data solution is output, and the common satellite number participating in the triangular network and its baseline data solution is displayed in real time on the software interface. To judge the solution quality of the CORS triangular network, it is necessary to first find the value of the common satellite number of the triangular network and its baseline from the software interface, and then compare it with the specified value. This method cannot directly obtain the solution quality of the entire CORS triangular network, nor can it quickly judge which area of the CORS triangular network has a problem in the solution, and the basis for judging the solution quality is not comprehensive enough. Summary of the Invention

[0004] The present invention provides a method, a server, and a client for displaying the solution quality of a CORS triangular network, which can obtain the solution quality of the CORS triangular network more quickly, intuitively, and accurately.

[0005] In a first aspect, an embodiment of the present invention provides a method for displaying the solution quality of a CORS triangular network, which is applicable to a server. The method for displaying the solution quality of a CORS triangular network includes:

[0006] Receiving request parameters sent by a client, and obtaining corresponding CORS triangular network solution data from a database according to the request parameters; wherein, the CORS triangular network solution data includes the number of common satellites in the CORS triangular network solution, the change rate of the CORS triangular network solution data stream, the number of common satellites in the baseline solution of the CORS triangular network, and the change rate of the CORS triangular network baseline solution data stream;

[0009] In the embodiment of the present invention, the solution quality of the CORS triangular network is judged by calculating the number of common satellites and the change rate of the solution data stream. Considering the number of visible satellites and signal stability at the same time, the accuracy of the solution quality judgment of the CORS triangular network can be improved; the solution quality of the CORS triangular network is judged by the solution data of the CORS triangular network and the solution data of the CORS triangular network baseline, which can facilitate the subsequent positioning of the area with poor solution quality in the CORS triangular network; by filling the corresponding CORS triangular network area with color according to the solution quality judgment result, the situation of the CORS triangular network solution quality can be obtained more intuitively. Compared with the prior art that judges the solution quality by the value of the number of common satellites in the CORS triangular network solution, the present application can obtain the situation of the CORS triangular network solution quality more quickly, intuitively and accurately.

[0010] Further, the judging the solution quality of the CORS triangular network solution data according to a preset threshold to obtain corresponding color coding data includes:

[0011] Comparing the number of common satellites in the CORS triangular network solution with a preset first threshold to obtain first CORS triangular network color coding data; wherein, the display result of the first CORS triangular network color coding data includes normal, warning and abnormal;

[0020] In the embodiment of the present invention, the solution quality of the CORS triangular network is judged by the number of common satellites in the CORS triangular network solution and the change rate of the CORS triangular network solution data stream. Considering both the number of visible satellites and signal stability, the accuracy of the solution quality judgment of the CORS triangular network can be improved; by filling the CORS triangular network with colors according to the solution quality judgment result of the CORS triangular network, the situation of the solution quality of the CORS triangular network can be obtained more intuitively.

Compared with the prior art that judges the solution quality by the value of the number of common satellites in the CORS triangulation network solution, the present application can obtain the solution quality situation of the CORS triangulation network more quickly, intuitively and accurately.

[0031] Further, the color-coded data is obtained by the server judging the solution quality of the CORS triangulation network data according to a preset threshold, and includes:

If the data stream change rate is less than 95%, it means that the real-time performance of at least 6 seconds of data within 120 seconds for the triangular network and its baseline, that is, the output data frequency is lower than 1 Hz). When the number of common satellites for CORS triangular network solution is greater than 4, the display result of the color-coded data of the first CORS triangular network is normal; when the number of common satellites for CORS triangular network solution is equal to 4, the display result of the color-coded data of the first CORS triangular network is a warning; when the number of common satellites for CORS triangular network solution is less than 4, the display result of the color-coded data of the first CORS triangular network is abnormal.
