| 摘 要： | 在机场抢修抢建中,对测量系统的作业时间、定位精度、可靠性具有较高的要求,本文提出了一种新型高精度IMU/TS组合定位导航方法,引入激光跟踪定位/惯性组合导航理念,分析了系统组成以及各传感器的误差项,将系统时间延迟作为新的状态估计参数,采用卡尔曼滤波器将IMU和TS数据进行数据融合处理,并在车载动态应用条件下同IMU/GPS组合定位导航系统进行了实验数据比对,验证了在无GNSS信号环境下IMU/TS组合定位导航系统的位置测量精度。

| Abstract: | In order to satisfy the requirement of high precision positioning and attitude determining for space debris removal and rendezvous and docking, this paper proposed a new high precision IMU/TS combined guidance method, imported laser tracking positioning and 1MU combined guidance principle. It analyzes system composition and sensor errors, and sets the system time delay as new state estimation parameter, couples the IMU and TS data by kalman filter. By experiments on a car, it compares with IMU/GPS combined navigation system, verifies the precision of IMU/TS combined navigation system under GNSS signal-less environment. |
