# Navtech_NV-GI120安装指南

```
NV-GI120 is a position and orientation system for automatic drive of NAV Technology. With the
high-precision GNSS board card and high-precision MEMS gyro, it has the real-time attitude 
and position resolving ability while transmitting the original data of the sensor and board card 
for post-processing high-precision resolution.
