CHCNAV X7/I83 GNSS Receiver with UM980 Motherboard and IMU for Land Surveying Base Kit And Rover Kit Price

34 hours on single charge to ensure operation when you need it 

The i83 GNSS ultra-low-power SoC (System-on-Chip) electronic design and smart power management dramatically improve GNSS survey time span and eliminate the need for spare or external batteries. Up to 34 hours of autonomous work are achieved when operated as a GNSS RTK network rover and up to 16 hours as an RTK base station. i83 GNSS charges from a power bank or a standard USB-C charger. No matter where or when the GNSS surveys are carried out, the i83 GNSS' magnesium alloy body is shock-, dust- and waterproof to ensure uninterrupted performance, even in the most demanding job site conditions. 

Unrivaled universal GNSS receiver 

i83 GNSS has all the connectivity features a surveyor needs to complete any GNSS surveying project scenario. Built-in Wi-Fi, Bluetooth, and NFC technologies provide a seamless connection to field data controllers and tablets. Integrated 4G and UHF modems enable any GNSS surveying mode, from RTK Networks NTRIP connections to UHF base- rover configuration. GNSS RTK corrections are accessed or broadcasted continuously for accurate positioning in all circumstances. The high-resolution color display provides a clear view of the i83 GNSS status. Whether it is set up as a UHF RTK base station, recording raw data for further GNSS post-processing, or simply being used as a UHF or 4G network rover, it provides the full control of survey operations. 

Efficient IMU-RTK survey made easy 

The i83 GNSS built-in IMU for automatic pole tilt compensation boosts surveying, engineering, and mapping speed and efficiency by up to 30%. Real-time, interference-free initialization of the 200 Hz inertial module is achieved in just 5 seconds and ensures 3-centimeter accuracy over a pole tilt range of up to 30 degrees. Measuring and staking out with the i83 GNSS is fast, easy, and highly productive, whether you are an engineer, site foreman, or surveyor
