| 摘 要： | 在本文中叙述了利用卡尔曼德波器对ＧＰＳ、惯导系统信息进行综合的建模方法及仿真结果，说明ＧＰＳ和惯导组合不但可以提高制导精度，还可估计制导误差。对几种组合制导方案的精度进行了比较，在飞行条件下对惯性仪表误差系数进行了估计。

| Abstract: | Modelling method and simulation result by using kalman filter for GPS-INS information processing are described in this paper.Effects of integration of GPS and inertial guidance not only can raise guidance accuracy but also may evaluate guidance error.Comparison of the accuracies of several integrated guid ance schemes is performed.Finally,error coefficients of some inertial devices are evaluted under flight condition. |
