RTK GNSS Receiver CHC i90 differential gps land survey instruments

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.

OVERVIEW

The i90 GNSS receiver offers integrated IMU-RTK technology to provide a robust and accurate positioning, in any circumstances. Unlike the standard MEMS-based GNSS receivers, the i90 GNSS IMU-RTK combines 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 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.
