【摘要】：針對(duì)傳統(tǒng)慣導(dǎo)在極區(qū)不適用的問題,文中建立了基于橫向地球坐標(biāo)的慣導(dǎo)機(jī)械編排,據(jù)此建立了基于橫向地球坐標(biāo)的慣性導(dǎo)航系統(tǒng)誤差模型.以某型船舶為例,通過系統(tǒng)性能的靜基座、動(dòng)基座仿真分析,研究了系統(tǒng)在極區(qū)的適用性.在動(dòng)基座仿真分析中,為船舶規(guī)劃了一條穿越北極點(diǎn)的航跡,模擬了船舶的復(fù)雜運(yùn)動(dòng)狀態(tài).仿真結(jié)果表明,基于橫向地球坐標(biāo)的慣性導(dǎo)航系統(tǒng)克服了傳統(tǒng)慣導(dǎo)不適用于極區(qū)的問題,還可以為極區(qū)航行的船舶提供高精度的偽姿態(tài)、偽位置信息.
[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.
