摘要

根据无人机的飞行任务需要, 提出一种适用于无人机的地形匹配辅助导航系统。该系统采用TERCOM算法和SITAN算法相结合的地形匹配组合导航算法, 以满足无人机机动飞行情况下连续匹配的要求。为验证系统的有效性, 根据真实地形数据, 建立由数字飞机、飞行控制系统、惯性导航系统和地形匹配系统组成的闭环仿真平台, 研究了不同飞行条件对导航精度的影响。仿真结果表明, 该系统能够有效提高无人机的自主导航精度, 具有较高的工程实用价值。

Abstract

According to the mission requirements of UAVsa terrain matching aided navigation system adaptable for UAV use is proposed.The system combines TERCOM algorithm with SITAN algorithm to meet the continuous matching requirement of UAVs in the case of its maneuvering.To verify the effectiveness of the systema closed-loop simulation platform consisting of digital planeflight control systeminertial navigation system and terrain matching system is established based on real terrain data.The impact of different flight conditions on navigation accuracy is studied.The simulation results illustrates that this system can improve the accuracy of the UAV autonomous navigation effectively and has a high practical application value.
