Product Description 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 60 degrees, A90 still could get the right point data by automatic correct system.
5. Applies WIFI connection to realize WebUI control designed to modify settings and monitor the receiver status
6. Bundled Android field software brings a big change in user experience and accessibility
