The integrated system is composed of SINS and GPS, each subsystem's navigational parameter is sent to navigation computer. At there the azimuth and attitude angle error is estimated by Kalman filter, then be used to adjust the attitude matrix of SINS. 组合系统由SINS、GPS两个系统构成,各子系统的导航信息输出至导航计算机,应用卡尔曼滤波方法估计三个方向的失准角,并对SINS系统的姿态矩阵进行校正。
Design on Navigational Parameter Compute Software and Man-Machine Interface of Loran-C Receiver 罗兰C接收机导航数据解算软件及人机界面设计
Navigational parameter by the Loran-C receiver measuring is time-difference ( TD) from user to three ( or more) launchers. These parameter must be transformed into geographic coordinate, and calculated further other parameter which be interested of user. 实际测量中,罗兰C接收机获取的导航定位参量是用户到三个(或多个)发射台间的时差,接收机需要将测量时差转化为地理经纬度,进而求取其它航行参数。
Position fixed and navigational parameter computed for vehicle is the basic task of the navigator. 确定运载体当前所处的位置及其航行参数是导航接收机应完成的最基本的任务。
