Description

  • 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 environments.

 

  • 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 built-in IMU ensures interference-free and automatic pole-tilt compensation in real time. 3 cm accuracy is achieved with a pole-tilt range of up to 30 degrees.
