The i73 GNSS receiver removes barriers to portability without sacrificing performance. Featuring full GNSS technology, it offers best-in-class GNSS signal tracking even in a harsh environment, enabling GNSS surveying beyond usual constraints. The i73 GNSS incorporates the latest innovations such as an inertial module providing automatic pole-tilt compensation in a very compact design. Connected to a GNSS RTK network via CHCNAV LandStar field software, or combined with the iBase GNSS receiver, the i73 GNSS is a highly productive rover for surveying and stakeout in any topographic, mapping or construction site applications.
