CHC Navigation has announced major updates to its i93, i85 and i76 GNSS receivers, as well as the iBase professional base station. The updates are designed to further improve positioning stability, simplify field setup, and expand operational capability across demanding surveying environments.
Enhanced RTK performance with the CHCNAV StellaX GNSS chip
The updated i93, i85 and i76 receivers integrate the CHCNAV StellaX GNSS chip with multi frequency signal tracking and advanced anti interference mitigation. This design is intended to support more reliable GNSS RTK positioning and more consistent data collection in complex terrain and in areas with partial GNSS satellite visibility.
PointSky GNSS corrections service for remote surveying
To reduce reliance on cellular networks and local radio links, the updated i93 and i85 now include a one-year standard subscription to the CHCNAV PointSky service. PointSky delivers GNSS corrections via satellite, enabling users to reach a 2.5 cm precision fix in three to five minutes. This capability supports surveying operations in remote locations such as mountains, forests and deserts where network coverage can be limited or unavailable.
Longer range radio operation and simplified iBase startup
The iBase base station now integrates CHCNAV DistLink technology and improved data compression to increase radio sensitivity and support up to 30 km coverage for linear projects such as highways and railways. Power consumption has also been optimized to support more than 13 hours of continuous operation without external batteries. To streamline setup, iBase includes a one button startup sequence designed to automatically pair with rover units, reducing the need for manual parameter configuration in the field.
