Product Description

IMU Tilt Survey FOIF N90 GPS cros station Supporting Ntrip Gnss Rtk
Product Description
Function Feature
1. Compact design, more productive
2. Professional GNSS satellites tracked simultaneously( GPS, Glonass, Galileo, Beidou)
3. Automatic data collection during centering
4. When the pole is tilted in 30 degrees, N90 still could get the right point data by automatic correct system.
