Optimal selection method and device of reference station

Abstract

The invention provides an optimal selection method of a reference station. The optimal selection method of the reference station comprises the steps of S1, segmenting a target area based on the border of a coverage area of each reference station in the target area so as to obtain multiple coverage fragments, wherein the target area is the total coverage area of all the reference stations; S2, building a relation table between each reference station and the multiple coverage fragments based on the coverage relationship between each reference station and the multiple coverage fragments; and S3, judging whether the reference stations can be replaced respectively based on the relation table, and getting rid of the replaceable reference stations of the reference stations. The optimal selection method of the reference station can reduce the number of the reference stations distributed in the target area; and resources are saved. Meanwhile, due to the reduction of the number of the reference stations distributed in the target area, radio interference among the reference stations can be reduced, and normal operation of an automatic driving navigation system in the target area can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of satellite observation and navigation, and more specifically, to an optimal method and device of a reference station. Background technique [0002] In recent years, the application of automatic driving and navigation technology for agricultural machinery in my country has been developing vigorously. This technology has high operation accuracy, saves time and effort, and can significantly improve operation quality, land utilization rate and extend operation time. [0003] The automatic driving of agricultural machinery requires the use of carrier phase difference technology (Real Time Kinematic, RTK) to process the carrier phase observations of two measuring stations in real time, and send the carrier phase collected by the base station to the user receiver for difference calculation and coordinate calculation. It can obtain centimeter-level positioning accuracy in real time in the field. For this ...

Problems solved by technology

[0004] However, due to the lack of coordination of the site, power, and frequency of each base station when setting up base stations, radio interference between base stations is more common, specifically manifested as co-frequency interference, near-frequency interference or signal Suppression, etc., which will cause a large number of automatic driving navigation systems to fail to work normally
