摘要: 惯性/星光组合系统作为一种高精度的姿态测量设备，自身误差数量级为角秒级，其安装标校精度可达角分级，安装误差的标定残差直接影响定姿、定位精度。论文讨论分系统安装误差标定方式、阐述了惯性/星光组合系统标校原理。根据总体技术方案，研究了惯性/星光组合系统轴系的标校误差传递特性，提出了惯性/星光组合系统标校方案。重点分析了组合系统标校过程中安装误差、测量仪器误差等多种误差因素在组合系统中的影响，对转轴倾角影响、同轴误差、标校零位的误差进行了建模分析，优化了组合系统标校方法，提高了安装误差标校精度。
Abstract: As a high precision attitude measurement device, the INS/CNS integrated navigation system has error order of second and installation and calibration precision of minute. The calibration residue of installation error directly affects attitude determination and positioning precision. The paper discusses calibration method of sub-system installation error, and expounds calibration principles of INS/CNS integrated navigation system. According to overall technical solutions, this paper studies shafting calibration error transfer characteristics of INS/CNS integrated navigation system, and puts forward calibration solution for the system. It mainly analyzes impact of multiple error factors during system alliteration such as installation error and measurement instrument error on the integrated system, models and analyzes counter-shaft inclination effect, coaxial error and zero position calibration, optimizes calibration method for the system and improves installation error calibration precision.
