CHC i73+ gnss receiver :
1. Support IMU
2. Built-in integrated battery
3. Fast charging, can be fully charged in 1 hour
4.Small size, easy to carry
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.
Controller Software: LandStar8
1. Easy to use and learn, with powerful features
2. Simplified project and coordinated system management
3. CAD base map rendering in seconds
4. Cloud integration enables efficient collaboration from field to office
