Удосконалення методу раціонального розміщення базових станцій системи диференціальної корекції глобальної навігаційної супутникової системи

This study investigates the process of deploying base stations of the global navigation satellite system’s differential correction system. The task addressed is to reduce complexity of the differential correction system by optimizing the number and placement of base stations in the global navigation satellite system. The method for the rational placement of base stations of the global navigation satellite system’s differential correction system has been improved. In contrast to known ones, it involves the following: – initially filling the predefined area with Voronoi diagram pole points; – constructing the Voronoi diagram; – finding the centroids of the resulting cells as the positions of the centers of the Voronoi cells; – verifying that the condition for changing the positions of the centroids is satisfied; – verifying that the condition for finding the centroids within prohibited zones is met; – adjusting the positions of the centroids. An experimental study was conducted on the optimal placement of base stations for the differential correction system in the global navigation satellite system. A visual analysis was performed of the results of base station placement using the improved method and known coverage methods. A comparative visual analysis reveals better coverage of the target area when using the same number of base stations. A quantitative analysis showed that using the improved method reduces the number of base stations by 21% compared to known methods. At the same time, the condition of full coverage of the specified area was met. This, in turn, has made it possible to reduce the complexity and cost of the global navigation satellite system’s differential correction system. The scope of application of the improved method is the placement of base stations for the global navigation satellite system’s differential correction system.
