FOIF A90 GNSS Receiver Function Feature
1. Compact design, more productive
2. Professional GNSS satellites tracked simultaneously( GPS, Glonass, Galileo, Beidou)
3. Automatic data collection during centering
4. It could get the right point data by automatic correct system with IMU when the pole is tilted in 60 degrees.
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
Function Feature
1. Performance values assume minimum of five satellites, following the procedures recommended in the product manual,
High-multipath areas, high PDOP values and periods of severe atmospheric conditions may degrade performance.
*2. Long baselines, long occupations, precise ephemeris used.
