iRTK4 is a full-featured, intelligent GNSS receiver system equipped with an integrated

new-generation full-frequency antenna and advanced multi-channel engine, allowing

users to attain accurate, reliable solutions. Users can also take advantage of calibration-free tilt compensation technology without leveling the survey pole to collect point

data in more places. In addition, the Smart Base function in iRTK4 automatically pairs

the Rover with the Base by using Hi-Target global servers and ensuring communication

by providing the best connection.

The iRTK4 system can maximize your productivity in unprecedentedly challenging

environments with these powerful features and Hi-Survey Road Field Software.

The Function of GNSS

When high-precision antenna is applied to reference station and rover station in continuous operation, reference station obtains accurate position information through long-term observation, and transmits the observation data to control center in real time through data communication system, then control center calculates the error in the area. Corrections are sent to the rover through ground-based augmentation system, wide-area augmentation system and satellite-based augmentation system. With RTK real-time dynamic measurement technology, user can finally obtain accurate coordinate information.
