【摘要】：针对传统惯导在极区不适用的问题,文中建立了基于横向地球坐标的惯导机械编排,据此建立了基于横向地球坐标的惯性导航系统误差模型.以某型船舶为例,通过系统性能的静基座、动基座仿真分析,研究了系统在极区的适用性.在动基座仿真分析中,为船舶规划了一条穿越北极点的航迹,模拟了船舶的复杂运动状态.仿真结果表明,基于横向地球坐标的惯性导航系统克服了传统惯导不适用于极区的问题,还可以为极区航行的船舶提供高精度的伪姿态、伪位置信息.
[Abstract]:Aiming at the problem that traditional inertial navigation is not applicable in polar region, an inertial navigation system error model based on lateral Earth coordinate is established in this paper. Taking a certain ship as an example, the applicability of the system in polar region is studied through the simulation analysis of the static and moving pedestal of the system performance. In the simulation analysis of the moving base, a track through the North Pole is planned for the ship, and the complex motion state of the ship is simulated. The simulation results show that the inertial navigation system based on lateral Earth coordinates overcomes the problem that traditional inertial navigation is not suitable for polar regions, and it can also provide high precision pseudo-attitude and pseudo-position information for ships navigating in polar regions.
