摘要
针对极区“两高两低三复杂”特殊地理环境下,单独使用惯性导航系统无法满足载机全球长航时自主飞行导航精度要求的问题,提出基于格网框架的极区捷联惯性导航系统(SINS)/天文导航系统(CNS)组合导航方案,并对SINS/CNS组合导航系统在中低纬度与极区环境下的飞行进行仿真分析。仿真结果表明:中低纬度地区SINS/CNS组合方案同极区SINS/CNS组合方案导航精度基本一致;而且SINS/CNS组合导航在精度和性能等方面明显优于单独子系统,组合导航系统不仅有效抑制了陀螺漂移引起的误差,并且及时修正了系统输出的各项导航参数。
Because the Inertial Navigation System(INS)cannot meet the precision requirements of Global navigation in the special geographical environment of the polar regions,the SINS/CNS Integrated Navigation System of Transpolar Aircraft which based on Grid Reference Frame is paper presented and simulated. The result of simulation demonstrated that the precision of SINS/CNS Integrated Navigation System are matched in the middle and low latitudes and the polar region,and the SINS/CNS Integrated Navigation System is superior to the single subsystem in precision and performance,which not only effectively inhibits the error caused by gyro drift,but also corrects the navigation parameters of system without delay.
