High Performance IMU RTK GNSS Receiver CHC i90 Pro RTK GNSS
 |
The i90 Pro GNSS receiver combines the latest CHCNAV IMU-RTK technology with compatibility with L-BAND correction services to extend RTK positioning anywhere.
Unlike standard MEMS-based GNSS receivers, the i90 Pro GNSS IMU-RTK combines a state-of-the-art GNSS RTK engine, high-end calibration-free IMU sensors, and advanced GNSS tracking capabilities to provide RTK availability and reliability. It greatly improves sexuality.
i90 automatic pole tilt correction increases surveying and piling speeds by up to 20%. Construction and land surveying projects are realized with high productivity and reliability that pushes the limits of traditional GNSS RTK surveying.

Tracking multiple constellations Combine GPS, Gronus, Galileo, and Hokuto Powered by a 336-channel GNSS core engine, the i90 Pro offers robust and reliable RTK positioning for any surveying project or positioning application.
L-band PPP modification Supports L-band and RTX™ correction signals Connected to a third-party L-band correction service, the i90 Pro GNSS offers accurate positioning below decimeter in almost any region where RTK networks, GSM coverage, or traditional GNSS base stations are not available.
Extended connectivity Instant NFC Pairing for Controllers The i90 Pro GNSS combines high-end connectivity modules such as Bluetooth, Wifi, NFC, 4G, and UHF wireless modems. 4G modems provide ease of use when working within an RTK network. Built-in UHF radio modem allows long-range surveys from bases up to 5km to spacecraft
High accuracy. Anywhere Increases investigation and piling speed by up to 30% The i90 GNSS integrated IMU guarantees real-time automatic polar tilt compensation without interference. Accuracy of 3 cm is achieved over a pole tilt range of up to 30 degrees. |
