Differential GPS CHCNAV i90
FULL GNSS POSITIONING Combining GPS, Glonass, Galileo and BeiDou constellations The embedded 624-channel GNSS technology takes benefits 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. Download: EXTENDED CONNECTIVITY 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. 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.
