惯性定位系统，在惯性平台有三个互相垂直的轴，其中之一是“上”，使系统产生海拔为一体的输出。

Inertial positioning system, in which an inertial platform has three mutually perpendicular axes, one of which is "up", so that the system yields elevation as one of the outputs.

该系统通过综合技术将惯性导航系统与差分GPS有效组合，不仅定位精度高、工作可靠，而且输出信息实时、连续；

The system, by effectively integrating INS/DGPS, is not only with high positioning accuracy and working reliability, but also outputs real time and continuous information.
