i90 IMU-RTK GNSS GPS Receiver

i90 IMU-RTK GNSS GPS Receiver 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.
