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.To solve the problem of conventional INS not applicable to polar regions, a mechanization of inertial navigation system based on transverse terrestrial coordinate was presented. According to this mechanization, error model of inertial navigation system based on transverse terrestrial coordinate was established. Taking a certain type of naval vessel as an example, the applicability of the system for polar regions was studied by simulation a-nalysis of system performance under the static base and dynamic base. In the simulation analysis of dynamic base, a route across the north pole was planned for the ship which simulated the complex motion state of the ship. The simulation results show that inertial navigation system based on transverse terrestrial coordinate over-comes the shortcoming of conventional INS not suitable for polar regions, and it can also provide high precision false attitude and location information for polar navigation ships.
