Problems solved by technology

However, it is mostly analyzed from the perspective that the number of base stations is fixed and the deployment space is not limited.
In practical applications, it is often necessary to provide services for a three-dimensional space area, the deployment space of reference stations will be limited, and the number of navigation reference stations may change
Therefore, the method in the above literature is only applicable to the above few specific scenarios

Embodiment

[0064] Step 1: Transform the deployment area and service area into mathematical model;

[0065] 1.1 Regional Definition

[0066] The defined area is the space straight four prism, such as figure 1 As shown, the spatial straight four prism contains 6 parameters, namely the four vertices V1, V2, V3, V4, the height H, the center point C, C, respectively, the center point of the center of gravity, when H At 0, the area is a quadrilateral;

[0067] 1.2 Define the deployment area and service area

[0068] Depending on the requirements of the deployed area restrictions and service area scope, the parameters corresponding to the deployment area STA_AREA and the service area served_area are determined according to step 1.1;

[0069] Step 2: Service area sampling;

[0070] Since the service area served_area contains countless points, it cannot be directly calculated, and the calculation needs to be split and sampling, the specific steps are:

[0071] 2.1 Regional segmentation method

Abstract

The invention provides a navigation source deployment position method based on deployment area iterative segmentation, which comprises the following steps of: converting a given rough deployable area and a service area into a computable mathematical model, on the basis, gradually obtaining the deployment position of the base station with the optimal geometric distribution by utilizing an iterative calculation method according to the requirements of station distribution number, calculation time and the like; so that guarantee is provided for work of a regional navigation system, and the service performance of the navigation system is improved. According to the method, the deployment speed of the regional navigation reference station and the rationality of station distribution are greatly improved, and the calculated deployment position meets different geometric distribution requirements by changing the calculation criterion. A result can be quickly calculated, the operation time of the method is tens of seconds, and real-time application is met; the station distribution position with better geometric distribution is obtained. The problems that the number of the reference stations is fixed and the deployment space is limited are well solved.

Description

Technical field [0001] The present invention relates to the field of radio navigation and positioning, in particular a navigation source deployment location method. Background technique [0002] With the advancement of guardroom interference technology, in battlefield environments, the guard system is easily unavailable. At this time, regional emergency navigation is a feasible, effective navigation positioning means, and the navigation base station can be equipped with a fast deployment, providing high-performance navigation positioning services for the Guide Refuger. [0003] Since the distance between the navigation base station and the user in the regional emergency navigation is close, the geometric distribution of the base station is significant. [0004] There are many related research on radio navigation geometric distribution at home and abroad. Some methods have studied 6 pseudo-satellite geometric layout programs, 4 pseudo-satellite geometric layouts, design 4, 5, 9 ps...
