基于北斗差分的多目标协同相对定位技术

Multi-Objective Collaborative Relative Positioning Technology Based on DBDS

本文分析了有/无人机飞行编队、多车辆联动行进等应用场景对复杂环境下高精度、高可靠性的相对定位技术的实际应用需求,构建了多目标协同相对定位系统,在此基础上深入分析了北斗多频多路径实时探测、高可用增强组合相对定位、高完好性增强相对定位可信监测等技术,并结合应用方向和场景开展了初步的试验验证,采用实际数据验证了多动态目标、实时高精度、抗多径、高可信的相对定位能力。

This paper analyzes the practical application requirements of high-precision and high-reliability relative positioning technology in complex environments, and on this basis, the technology of Beidou multi-frequency multi-path real-time detection, perfect enhancement relative positioning reliable monitoring is studied. The multi-objective cooperative relative positioning principle system is constructed, and the preliminary experimental verification is carried out in combination with the application direction and scene, and the relatie positioning ability of multi-dynamic target, real-time high precision and high reliability is verified.
