本文介绍的这种新型惯性导航系统是我们研究室近年来所获得的研究成果。这种方案的特点起,从不同的途径来进行初始对准,系统本皇可以输出航向、纬度和水平信息,同时,航向和纬度信息都不存在随时间而积累的误差。文中,对这种系统的工作原理、误差分析、参数选择和试验结果都一一作了介绍。此外,为了进一步提高系统的精度,还提出了采用混合结构的卡尔曼泸波方案。
This new inertial navigation system introduced in this paper is the result of our research in recent years. The characteristics of this scheme, starting from a different approach to the initial alignment, the system itself can output heading, latitude and horizontal information, at the same time, the course and latitude information does not exist over time and error. In this paper, the working principle of this system, error analysis, parameter selection and test results are introduced one by one. In addition, in order to further improve the accuracy of the system, a hybrid Kalman-Laval scheme has also been proposed.
