Product Description
FULL GNSS POSITIONING
Combining GPS, Glonass, Galileo and BeiDou constellations
The embedded 624-channel GNSS technology takes benefit from all GPS, GLONASS, Galileo and BeiDou signals and provides robust RTK
position availability and reliability.
HASSLE-FREE IMU-RTK SURVEYING
Dramatically increase RTK availability
No complicated calibration process, rotation, leveling or accessories are necessary with the i90. Just a few meters walk will
initialize the i90 internal IMU module and enable RTK survey in difficult field environment.
EXTENDED CONNECTIVITY
Instant NFC pairing of your controller
The i90 GNSS combines high-end connectivity modules: Bluetooth, Wi-Fi, NFC, 4G, and UHF radio modem. The 4G modem brings ease of
use when working within RTK networks. The internal UHF radio modem allows long-distance base-to-rover surveying up to 5 km.
HIGH ACCURACY. ALWAYS
Boost survey and stakeout speed by up to 30%
The i90 GNSS build-in IMU ensures interference-free and automatic pole-tilt compensation in real-time. 3 cm accuracy is achieved
with pole-tilt range of up to 30 degrees.
