Then some previous good error models and some latest outcomes presented in the world are made full use of in order to make simulated gps data be very close to the real observations 算例结果表明: gps模拟观测值在星载gps定轨中方案比较、可行性论证中有重作用。
Another advantage of flp filter is that it can build error model at each startup of hrg , which has advantage in the case that the error model changes at the startups Flp滤波方法的另一优点是可以每次启动时进行随机建模,这就适用于每次启动时陀螺误差随机模型不同的情况。
And in the early time many integrated navigation error model was come into being . in all of them the model derivated by britting and widnall was the representative 最具代表性的是利用britting和widnall推导出的误差模型,该模型是基于地理系,考虑到系统误差和传感器误差。
Considering the error of the system and the error of the sensor , the error model of the system usually adopted the position velocity and gesture as state variable make up state equation 对于系统误差的数学模型一般都是采用位置、速度、姿态等作为状态变量建立系统的状态方程。
Begin with the study of error models and the analysis of observability , the author investigates the alignment problems , and designs software for simulation and actual application 本文把初始对准过程分成三个阶段进行研究:初始捷联矩阵的建立阶段、粗对准阶段和精对准阶段。
