Then, base on the problem of attitude control of a satellite under development, we design a NN compensation controller for high accuracy orientation phase.

然后，基于某型小卫星的姿态控制问题，设计了高精度定向阶段的神经网络补偿控制器。

At present, the scout orientation system of our navy fleet mainly depends on the long river No. 2 navigation system and satellite navigation system based on American GPS or Russia GLONASS.

目前，我海军舰船的监控定位主要依靠我国的长河二号导航系统和基于美国的GPS或俄罗斯的GLONASS的卫星定位系统。
