CHCNAV iBase GNSS
The CHCNAV iBase GNSS receiver is a fully integrated professional GNSS base station specifically designed to meet 95% of surveyors’ needs when working in UHF GNSS base and rover mode. The performance of the iBase UHF base station compared to a standard external UHF radio modem is almost perfect. But its unique design eliminates the need for a heavy external battery, cumbersome cables, external radio, and radio antenna. Its 5-watt radio module provides operational GNSS RTK coverage up to 25 km in optimal conditions, and a real-time UHF interference self-checking technique allows the operator to select the most appropriate frequency channel to use.

LOWER CONSUMPTION, LONGER AUTONOMY, BROADER COVERAGE
Increased performance with 50% less power consumption
The iBase GNSS electronics design significantly reduces power needs without sacrificing the UHF modem’s performance. Its two high-capacity removable batteries provide up to 12 hours of continuous operation when transmitting RTK corrections at 5 watts power output. With the UHF it can cover up to 25 km in optimal conditions and up to 5km under challenging conditions such as wooded and suburban areas.
BEST GNSS SIGNAL TRACKING IN ITS CLASS
Full GNSS with 1408 channels and advanced multipath mitigation.
The state-of-the-art 1408-channel GNSS technology leverages GPS, GLONASS, Galileo and BeiDou. The iBase GNSS integrates cutting-edge GNSS antenna technology and multipath mitigation algorithms to ensure that the highest quality GNSS corrections are transmitted to the GNSS rovers.


INDUSTRIAL GRADE DESIGN
Rugged conception for uninterrupted work
The i93 GNSS features CHCNAV’s state-of-the-art 200Hz Auto-IMU, which eliminates the need for manual initialization and simplifies surveying operations in the field. With IMU corrections available even when the range pole is carried on the shoulder, in hand, or placed horizontally, the i93’s IMU-RTK automatic pole tilt compensation technology can boost surveying, engineering, and mapping speed and efficiency by up to 30%. Measuring and staking out with survey-grade accuracy over a pole tilt of up to 60 degrees is fast, easy, and highly productive, making the i93 the perfect solution for engineers, site managers, and surveyors.



The iBase supports GPS, GLONASS, Galileo, and BeiDou constellations with robust signal tracking and high accuracy for surveying applications.
The iBase features Bluetooth V4.1, Wi-Fi 802.11 b/g/n, and a built-in UHF modem (410-470 MHz) for comprehensive connectivity and seamless data transmission.
The iBase’s built-in 5-watt UHF radio module provides GNSS RTK coverage up to 25 km under optimal conditions, ensuring extensive field coverage.
Yes, the iBase is IP67-rated for dust and water resistance and has an IK08-rated for shock resistance, securing reliable performance in various field conditions.
