摘　　要：为了降低姿态测量系统的启动漂移和标定误差,提高测量和导航精度,针对系统安装特色,提出了一种原位快速标定方案。分析了系统可观测性,利用等效陀螺信息推导了多位置原位标定方案;研究了最优标定和次优标定问题,分析了标定精度和坡度之间的关系;设计了一种针对系统安装特色的多位置编排方案,完成了大坡度范围下的原位标定。仿真结果表明:方案要求简单,应用范围广,能够完成大坡度范围下高精度快速标定,具有重要的工程应用价值。To reduce start-up drift and calibration error of the Gun Attitude Measuring System(GAMS)on armed chariot and improve precision of measurement and navigation,a design of in-situ rapid calibration is proposed with considerations of installation features. The system observability is analyzed and a multi-positions in-situ calibration strategy based on equivalent gyro information is derived. The optimum and suboptimum calibration schemes are researched,and the relation between calibration and ramp gradient is analyzed. A new method for multi-positions with GAMS characteristics is designed and an in-situ calibration under large range of gradient finished. The simulation results show that it requires simple condition with a wide application and obtains a fast and high-accuracy calibration under large range of gradient,and has an important application value.
