Embodiment Construction

[0040] The present invention will be further explained below in conjunction with the accompanying drawings.

[0041] A grid-based differential platform server network architecture setting method, comprising the following steps:

[0042] Step 1), divide the entire Chinese region according to the longitude step l 0 , latitude step b 0 To divide the grid, the longitude range of the Chinese region is: 73°33′-175°05′, the latitude range is 3°51′-53°33′, and the starting latitude B of the grid division is set 0 = 4, the maximum latitude B M = 54, then China’s spanning in latitude is B d =50; set the starting longitude L of the division grid 0 =73, the maximum longitude L M =175, then China’s longitude span is L d =52; In the present embodiment, the longitude step size b 0 Take 0.25, latitude step l 0 Take 0.25. Then, the grid is divided into sub-regions according to the geographical area; in the present embodiment, the grid is divided into sub-regions according to the provi...

Abstract

The invention discloses a grid-based difference platform server network architecture setting method, and solves a high concurrency problem of a lot of users during high-precision positioning in the future. According to the method, based on a virtual grid strategy, a reference station area is divided into a plurality of grids according to distance or areas. In the method, difference servers are set based on a grid. Servers are divided according to grid areas; each area is configured with a server or a plurality of servers used for receiving grid virtual data from a data processing center and sending the received virtual data to terminals for differential positioning; and when one server reaches a full load, all that is needed is to add the same server, so that through the manner, an efficient and reliable solution is provided for the high concurrency problem of a lot of the users in a high-precision positioning service process.

Description

technical field [0001] The invention relates to the field of satellite positioning, in particular to the application of satellite positioning in the positioning of large users and high concurrency. Background technique [0002] The pseudo-range differential positioning method based on the virtual grid adopts the pseudo-range differential positioning strategy based on the grid, divides the reference station area into several grids according to the distance or area, and uses the interpolation method to interpolate the virtual observation values ​​of the grid points. Then the data processing center selects the grid point closest to the user terminal according to the approximate coordinates uploaded by the user, and sends the virtual observation value of the grid point to the user for pseudorange differential positioning. Due to the structural problems of the server in traditional GNSS positioning, the number of terminals that the server can access is severely limited. Generally...
