| 摘 要： | 常规的惯性/星光组合导航多基于姿态信息组合,对位置、速度修正效果较差.针对上述问题,在惯性/星光姿态组合算法基础上,通过引入基于星光折射原理后获得的天文定位信息,设计了惯性/星光姿态、位置全组合导航方案,并提出了基于地心惯性坐标系下的捷联惯性/星光全组合导航算法.仿真结果表明:由于利用星光折射间接敏感地平的方法,在系统中引入了位置相关的观测信息,可确保组合导航系统获得较高的位置、速度和姿态精度.

| Abstract: | Most conventional inertial navigation system/celestial navigation system (INS/CNS) integrated navigation are based on attitude information combination,can not correct position and velocity error effectively.Aiming at this problem,on the basis of INS/CNS attitude integrated algorithm,design INS/CNS attitude and position complete integrated navigation scheme aided by introducing stellar refraction principle acquired astronomical positioning information,and put forward SINS/CNS complete integrated algorithm in earth centered inertial coordinate system.And the simulation results show because using stellar refraction to indirectly sense the Earth horizon,introduce location-related observation information in system,can ensure integrated navigation system has high degree of position,velocity and attitude precision. |
