车载SINS-DGPS-里程计组合系统捷联起始姿态角确定方法
摘要
在有些特殊应用场合如车载移动测图系统
要求的是高精度的定位定姿结果而不要求实时性
针对这一应用特点
提出了使用DGPS的位置信息来纠正SINS的起始失准角误差
实际应用表明:该方法取得了较好的效果
可满足工程应用的要求。
Abstract
In special area such as vehicle mobile mapping system
post high accuracy of position and attitude is required.Contraposed to these characteristics of the integrated system
a new method which using the position information of DGPS to calibrate misalignment angle of static initial self-alignment is introduced.The practical application results illustrate the efficiency of the new method
which can be accorded with the demand of engineering.
