CHCNAV i83 Pro Receiver IMU-RTK GNSS

SUPERIOR GNSS TECHNOLOGY

Powered by 336-channel GNSS and iStar technology
The i83 Pro GNSS smart antenna delivers centimeter-level precision in seconds, maintaining consistent RTK accuracy even in challenging environments. Its high gain antenna increases GNSS satellite signal tracking efficiency by up to 30%, ensuring accurate, survey-grade positioning using GPS, GLONASS, BeiDou, Galileo, and QZSS constellations. Integrated iStar technology optimizes GNSS RTK surveying for all applications, guaranteeing superior performance.

COMPREHENSIVE CONNECTIVITY

Smarter Connectivity for Every Project
The i83 Pro GNSS offers comprehensive connectivity essential for any surveying project. With built-in Wi-Fi, Bluetooth, NFC, 4G, and UHF modems, it supports diverse GNSS surveying modes, including RTK Networks NTRIP and UHF base-rover configurations. Continuous GNSS RTK corrections ensure precise positioning, supported by VRS, FKP, and MAC for Network RTK. RTCM State Space Representation (SSR) messages enable improved positioning accuracy. The high-resolution color display provides a clear view of the i83 Pro GNSS status. Whether used as a UHF base station, for data recording, or as a UHF or 4G network rover, the i83 Pro puts surveyors in full command of their operations.

ENHANCED AND VERSATILE FUNCTIONALITY

Extended Capabilities for Advanced Surveying
The i83 Pro offers optional advanced features like Trimble RTX and OmniSTAR support, delivering RTK-level accuracy without a base station or VRS network. The optional Trimble MAXPro Positioning Engine ensures exceptional performance in difficult GNSS conditions. Additional features include Fault Detection & Exclusion (FDE) and Receiver Autonomous Integrity Monitoring (RAIM), which enhance position quality by identifying and mitigating satellite measurement issues. The receiver supports flexible data rates, including 20Hz and optional 50Hz outputs for raw observations and positioning results.

EFFICIENT IMU-RTK SURVEYING

Efficient IMU-RTK survey made easy Auto-IMU for Enhanced Productivity
The i83 Pro GNSS receiver's built-in AUTO-IMU offers automatic pole tilt compensation, enhancing surveying, engineering, and mapping efficiency by up to 30%. The 200 Hz inertial module automatically achieves real-time, interference-free initialization, ensuring 3-centimeter accuracy over a pole tilt range of up to 60 degrees. This makes measuring and staking out with the i83 Pro fast, easy, and highly productive for engineers, site foremen, and surveyors.
