The state equation and error analysis of SINS combined with globe positioning system (GPS) and Doppler navigation system (DNS) were also presented.
给出了SINS与全球卫星定位系统(GPS)、多普勒导航系统(DNS)组合导航系统的状态方程和误差分析，在给定条件下进行了仿真试验。
In the satellite navigation and positioning system, Doppler shift is one of the key problems that may degrade the performance of the satellite receiver.
在卫星导航定位系统中，多普勒频率偏移是影响接收机性能的关键因素之一。
A simple inertial or Doppler navigation has a common defect that position errors are always increasing with flight time or distance, therefore an external reference system is necessary.
纯惯性导航或多普勒导航的一个共同缺点是：一般都具有随时问或距离增长的位置误差，这就需要有一个外基准系统。
