针对无依托发射作战应用背景下导弹发射车车载定位定向技术存在的问题,提出一种基于射频识别(RFID)辅助的捷联惯导(SINS)/里程计(OD)组合导航的方案。设计了发射车利用RFID进行定位的多种方式,分析了实际使用的相关问题,并将其应用在较为成熟的SINS/OD模式中,建立SINS/OD/RFID模型,进行了行进间辅助定位的方法探究,为车载定位定向发展提供一种新角度新辅助方式。实验结果表明,该方案定位精度达到米级,有效延长满足精度要求的导航时间,提高了使用效能。

To solve the problems in the positioning and orientation technology of the missile launching vehicle in the background of independent emission, a scheme of integrated navigation of SINS/odometer (OD) based on Radio-Frequency Identification (RFID) is presented.A variety of positioning approaches based on RFID for the launching vehicle are designed and the related problems in actual use are analyzed.Then the scheme is applied to the mature SINS/OD mode.The model of SINS/OD/RFID is built, and the approaches to the auxiliary positioning in progressing are explored, which provide a new auxiliary method for the positioning and orientation development of the launching vehicle.The experimental results of this scheme show that, the positioning accuracy can reach the level of meter, which can effectively extend the navigation time meeting the precision requirements, and improve the application performance.
