CHCNAV i90 PRO IMU-RTK GNSS
Description
The i90 Pro GNSS receiver combines the latest CHCNAV’s IMU-RTK technology and the compatibility with L-Band corrections services to extend RTK positioning, in any location. It integrates a state-of-the-art GNSS RTK engine, a calibration-free high-end IMU sensor and advanced GNSS tracking capabilities to dramatically increase RTK availability and reliability.
The i90 Pro automatic pole-tilt compensation boosts survey and stakeout speed by up to 30%. Construction and land surveying projects are achieved with high productivity and reliability pushing the boundaries of conventional GNSS RTK survey.
Features
FULL GNSS POSITIONING
Combining GPS, Glonass, Galileo and BeiDou constellations
The embedded 336-channel GNSS technology takes benefit from all GPS, GLONASS, Galileo and BeiDou signals and provides robust RTK position availability and reliability to any surveying project and positioning application.
EXTENDED CONNECTIVITY
Instant NFC pairing of your controller.
The i90 Pro 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.
L-BAND PPP CORRECTIONS
Compatible with L-Band and RTX™ correction signals
Connected to 3rd party L-Band corrections services, the i90 Pro GNSS provides accurate, sub-decimeter positioning in virtually all regions where RTK networks, GSM coverage or traditional GNSS base station are not available.
HIGH ACCURACY. ALWAYS
Boost survey and stakeout speed by 30%.
The i90 Pro GNSS build-in IMU ensures interference-free a n d automatic pole-tilt compensation in real-time. 3 cm accuracy is achieved with pole-tilt range of up to 30 degrees.
HASSLE-FREE IMU-RTK SURVEYING
Dramatically increase RTK availability.
No complicated calibration process, rotation, leveling or accessories are necessary with the i90. Simply rock the range pole a few times to initialize the i90 Pro internal IMU module and enable GNSS RTK survey in difficult field environment.
