[0026] The following is an explanation of the terms that may be involved in this application, as follows: Differential correction is a technology used to improve positioning accuracy in the Global Navigation Satellite System (GNSS). It is done by continuously observing at a base station with known coordinates, calculating the pseudo-range observation correction or coordinate correction, and providing it to the mobile station (user equipment) to correct the pseudo-range observation of the mobile station or directly perform coordinate correction, thereby improving the positioning accuracy of the mobile station.

[0027] GGA is a data format in the Global Positioning System (GPS). Its full name is "Global Positioning System Fix Data", i.e. GPS positioning data. It is a standardized output statement used to obtain location information from a GPS receiver. GGA statements are usually updated once a second and contain key positioning information such as location, time, positioning quality indication, etc.

[0028] SSR2OSR refers to the process of converting from State Space Representation (SSR) to Observation Space Representation (OSR). SSR and OSR are two different GNSS augmentation service technologies.

[0029] Please refer to Figure 2 , Figure 2 A schematic diagram of the structure of a positioning assessment system is shown, wherein the positioning assessment device 1 comprises: Multiple input interfaces 10 are electrically connected to at least one preset type positioning terminal 2, and are used to obtain and publish preset type information corresponding to the preset type positioning terminal 2. Specifically, in this embodiment, the positioning evaluation device 1 is configured with multiple input interfaces 10. The input interface 10 can be, for example, a serial port, and the preset type positioning terminal 2 is connected to the positioning evaluation device 1 via a serial port. In this way, the input interface 10 can collect the preset type information corresponding to the preset type positioning terminal 2 and publish it, so that multiple server interfaces 11 or the first algorithm module 12 can subscribe to the preset type information according to actual test needs. Among them, the preset type information can be, for example, GNSS observations, GGA, etc., which are not limited here.

[0030] Multiple server interfaces 11, each server interface 11 is connected in communication with the corresponding server 3, and is used to send the acquired preset type information to the corresponding server 3, and obtain the differential data returned by the server 3. Specifically, in this embodiment, the positioning evaluation device 1 is configured with multiple server interfaces 11, and each server interface 11 is connected in communication with the corresponding server 3 through an account provided by the positioning service provider. The server interface 11 obtains the preset type information by subscription and sends it to the corresponding server 3. The server 3 obtains the differential data after solving the preset type information. The server interface 11 is also used to receive the differential data returned by the server 3 and publish the differential data. Among them, the differential data can be a differential correction number, which includes but is not limited to position difference, pseudorange difference, phase difference, and distance correction number, etc., which are not limited here.

[0031] The first algorithm module 12 is used to obtain the positioning evaluation result of each server 3 according to the differential data, and / or the positioning evaluation result of at least one preset type of positioning terminal 2. Specifically, in this embodiment, the positioning evaluation device 1 is configured with a first algorithm module 12, wherein the first algorithm module 12 can integrate different positioning algorithms, and / or the first algorithm module 12 includes a plurality of algorithm units, each of which integrates a different positioning algorithm. The first algorithm module 12 obtains the differential data published by the server interface 11 by subscription, so that when it is necessary to test and evaluate the service quality of the positioning service provider, the positioning evaluation result of each server 3 is obtained according to the differential data, and / or, when it is necessary to test and evaluate the algorithm capability of the preset type of positioning terminal 2, the positioning evaluation result of the preset type of positioning terminal 2 is obtained according to the differential data.

[0032] Furthermore, in the positioning evaluation device 1, each process adopts a publish-subscribe communication mode. Each module publishes data, and other required process bureaus can automatically subscribe to relevant data according to test needs. A module can be a data subscriber and a data publisher at the same time without interfering with each other, so that each data can be reused most efficiently. In an application scenario, by adopting the positioning evaluation device 1 provided by the present application, for dynamic road testing of vehicles on the road, the time required for various tests can be significantly reduced.

[0033] Through the cooperation of the above-mentioned multiple input interfaces 10, multiple server interfaces 11 and the first algorithm module 12, the multiple input interfaces 10 can provide multiple preset type positioning terminals 2 for connection at the same time, and the multiple server interfaces 11 can establish a connection with the multi-channel server 3. The positioning evaluation device 1 proposed in this application, the first algorithm module 12 can run multiple processes at the same time, and each algorithm process subscribes to the server interface 11 required by itself, so: (1) When the test requirement is to use the same model of positioning terminal to test the service quality of N positioning service providers, the existing technology requires the configuration of N server host computers + N positioning terminals, which is reduced to a positioning evaluation device 1 + N positioning terminals proposed in this application, significantly reducing the demand for server host computers in this test situation.

[0034] (2) When the test requirement is to test the performance of N positioning terminals using the services provided by the same positioning service provider, the existing technology requires N server host computers + N positioning terminals, which is reduced to a positioning evaluation device of 1 + N positioning terminals proposed in this application, significantly reducing the demand for server host computers in this test situation.

[0035] (3) When the test requirement is to use the same version of the algorithm to test the service quality of N positioning service providers, the existing technology requires N server-side host computers + N positioning terminals, which is reduced to a positioning evaluation device 1 + 1 positioning terminal proposed in this application. The algorithm of this version integrated in the first algorithm module 12 can simultaneously subscribe to the differential data corresponding to the N positioning terminals and generate corresponding positioning evaluation results, which significantly reduces the demand for server-side host computers and test terminals in this test situation.

[0036] (4) When the test requirement is to use the service provided by the same positioning service provider to test the performance of different versions of algorithms, the existing technology requires N server host computers + N positioning terminals, which is reduced to a positioning evaluation device 1 + 1 positioning terminal proposed in this application. The different versions of algorithms integrated in the first algorithm module 12 can subscribe to the differential data of the positioning terminal respectively published by multiple server 3 interfaces 11, and generate corresponding positioning evaluation results, which significantly reduces the demand for server host computers and test terminals in this test situation.
