Product Description

Hi-target irtk4 GNSS RECEIVER:
Adopt ultra-high precision inertial measurement module IMU. The unique tilt compensation function realizes the practicality of RTK tilt measurement, and the measurement efficiency is increased by 20%. The controller is equipped with a 5.5-inch highlighted touch screen.

 

The irtk4 can contribute more to the land survey.
1) Hi-Target has set its self-developed multi-protocol UHF modem into the enclosure.
2) the irtk4  built-in 6800mAh lithium battery can work continuously for more than 10 hours in rover mode.

The irtk4 adopts new features to satisfy more work scenarios and usage needs.
1) Full-constellation and Signal Tracking
2) Tilt Compensation
The irtk4 GNSS receiver integrates Hi-Target's latest tilt compensation algorithm and built-in high-performance inertial measurement unit (IMU)
3) Hi-Fix
The irtk4  is equipped with the Hi-Fix function of Hi-Target. It ensures that the GNSS receiver still maintains the output of high precision RTK positioning results when the correction data is lost. This also ensures the fieldwork can continue to the maximum extent.
