Problems solved by technology

The traditional satellite selection method uses the traversal method to calculate and compare all visible satellite combinations, which requires a large amount of calculation and unsatisfactory real-time performance
With the rise and development of computing intelligence, the fast satellite selection method based on heuristic algorithm is used to quickly select a suitable subset of visible satellites to optimize the navigation and positioning effect. However, this type of algorithm has the problem of falling into local optimum and The calculation process needs to adjust too many parameters

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] combine Figure 1 to Figure 2 , the technical scheme adopted in the present invention is:

[0042] The invention is a Beidou navigation satellite selection method based on tabu search artificial bee colony algorithm, which is characterized by selecting the best visible satellite combination for the purpose of optimizing the navigation and positioning GDOP value. The star selection process proceeds as follows:

[0043] Step 1. Obtain the current ground observation point position parameter vector L o = [B o , L o , H o ], where B o , L o , H o They are the geodetic latitude, geodetic longitude, and geodetic height data of the current ground observation point. Get all Beidou navigation position parameter vector L at the current moment i = [B i , L i , H i ], where B i , L i , H i Respectively represent the geodetic...

Abstract

The invention provides a Beidou navigation satellite selection method under a tabu search artificial bee colony algorithm, and the method comprises the steps: calculating the elevation angle and azimuth angle of each Beidou navigation satellite at a ground observation point through the obtained position information of the ground observation point and the real-time position information of the Beidou navigation satellite; screening the Beidou navigation satellites according to the shielding angles at the ground observation points to obtain a visual satellite set; using a tabu search artificial bee colony algorithm, using a geometric accuracy factor GDOP of a satellite combination scheme as a target function, optimizing and solving the satellite combination scheme in a solution space, and obtaining the satellite combination scheme with the minimum GDOP. According to the method, the artificial bee colony algorithm based on tabu search is applied to the Beidou navigation satellite selectionprocess, the advantages that the artificial bee colony algorithm is few in preset parameter and high in optimizing capacity, the optimizing speed is high and the like are brought into full play, theefficiency of the satellite selection process in Beidou navigation application is effectively improved, and the method has high value and practicability.

Description
