查询词典 loran

In order to ensure the precision and reliability, this paper designs the GPS/Loran C/SINS/AHRS integrated system. In this integrated system, the self-adaptive federated Kalman filter is introduced to revise strap-down inertial navigation system; the heading angle attitude and heading reference system is used to ensure the convergence of heading angle; and the coordination transformation for Loran C is applied to eliminate the constant error of Loran C.

针对导航精度及可靠性，设计了GPS/罗兰C/SINS/AHRS组合导航系统，该组合导航采用了自适应联邦卡尔曼滤波的方法，通过闭环形式校正SINS，并用姿态航向参考系统代替捷联惯性导航系统输出的航向角以保证航向角的收敛，同时对罗兰C的测量值进行坐标变换以消除由于坐标系不同而带来的常值误差。

The paper will show that, if appropriate time information are added into the signals over the Loran-C data channel (studied in the first part of the paper) or in which the current multi-chains signals can be skillfully dealt with(studied in the second part of the paper), the independence of Loran-C for precision timing can be perfected, as well as the precision of timing signals and the automatization level of UTC synchronization can be improved, thereby the Loran-C can be acceptant and employed widely.

本文通过研究认为，在罗兰C信道上增加合适的时间信息或利用多链罗兰C信息，能够完善罗兰C高精度授时的自主性，提高定时信号的精确度和用户定时的自动化水平，从而提升该系统的可利用度和可接受程度。作者所做工作及主要成果如下
