    CHC Navigation announces major updates to GNSS receivers and iBase

    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.

    CHC Navigation brings PointX and StellaX positioning to smart lawn mowing

    CHC Navigation announced at CES 2026 that MOVA has integrated CHCNAV PointX integrated satellite ground service and the StellaX high-precision positioning chip into its NAVAX 5000 AWD intelligent robotic lawn mower, unveiled at the show in Las Vegas last week.

    The integrated positioning solution is designed to support centimeter-level accuracy for wire-free mowing, without requiring users to install a local RTK base station or subscribe to cellular data plans.

    Wire-free robotic mowers are accelerating adoption of virtual boundaries and automated coverage. Many systems rely on local RTK reference stations, network RTK, or cloud connectivity, which can increase installation complexity and introduce ongoing service costs. CHCNAV and MOVA developed a positioning architecture designed to address these limitations through satellite delivered corrections combined with onboard sensor fusion.

    Wire-free mowing without local base stations

    NAVAX 5000 AWD uses CHCNAV PointX integrated satellite ground service to deliver GNSS enhancement signals via satellite. With the StellaX high-precision positioning chip, the mower can achieve centimeter-level positioning across supported regions without requiring users to deploy and maintain an RTK base station at home. This can reduce setup time, remove routine base station maintenance, and avoid recurring cellular data fees for positioning corrections.

    Residential yards often include trees, walls, fences and buildings that degrade satellite visibility and create multipath effects. NAVAX 5000 AWD combines satellite-based RTK positioning with binocular vision and lidar to strengthen navigation performance in these environments.

    With PointX and StellaX, the system is designed to deliver stable positioning and consistent path tracking in obstructed areas where traditional GPS RTK-only approaches can be difficult to sustain.

    PointX-integrated satellite ground services support rapid RTK initialization to reduce waiting time at startup. This enables power on and go operation for typical mowing sessions and supports repeated runs with minimal user intervention.
