Target localization method based on virtual anchor nodes of one single unmanned aerial vehicle

Abstract

Aiming at the GNSS rejection environment, or even the situation where GNSS is not available, this paper proposes a guided relative positioning method. This method takes advantage of the GNSS information from the known target to obtain the position formation of the intermediate target, and then calculate the final localization by the measurement information derived from the relative position information of the pending target. The simulation results indicate that the localizing accuracy of the guided relative positioning achieves the desired requirements, and the number of anchor nodes has a certain influence on the precision of the guided relative positioning method.
