| 摘 要： | 在无地面基准的机群编队飞行JTIDS/INS组合导航系统中,采用新的相对坐标系建立方法克服了绝对位置偏差对相对导航定位精度的影响,同时在原有的TOA观测量的基础上增加了DOA观测量,采用UKF非线性滤波算法进行系统滤波器设计,进一步提高了相对定位精度,并设计了JTIDS/INS组合导航仿真软件平台.仿真结果表明,该方法在收敛速度和定位精度方面都有很好的性能.

| Abstract: | In JTIDS/INS integrated navigation system without geographical position reference(GPR) for aircraft formation flying,a new relative coordinate establishing method is proposed to overcome the affect of the absolute position error.Based on original TOA observation,the DOA observation is introduced.In order to further improve the relative position accuracy,the unscented Kalman filter algorithm is adopted for system filter design.Then the JTIDS/INS integrated navigation system simulation platform is designed.The simulation result shows that the proposed method perform well in convergence and position accuracy. |
