Shanghai, China, June 18, 2026. CHC Navigation (CHCNAV), a global provider of geospatial solutions, announced a major update to the CHCNAV i85, a compact laser IMU RTK GNSS receiver designed for efficient daily land surveying. The updated i85 extends its laser measurement capability up to 150 m under favorable conditions and adds compatibility with CHCNAV PointSky L-band GNSS correction services, helping surveyors capture remote points and work more efficiently in areas where network RTK access is limited or unavailable.
The updated i85 features a visible green laser with a measurement range of up to 150 m under favorable conditions. The laser is designed to remain visible in bright outdoor conditions, and resist ambient light levels of up to 50,000 lux. By combining GNSS positioning and laser ranging, the i85 enables survey-grade 3D coordinate collection without requiring direct physical access to every point. Surveyors can measure building corners, road edges, fences, utility assets, slopes, embankments, and other hard-to-reach features from safer or more convenient positions.
The i85 integrates high-precision IMU tilt compensation to help users collect points without keeping the pole perfectly vertical. In high-accuracy laser survey mode, the receiver supports 3 cm measurement accuracy at a 10 m distance, helping maintain reliable results when capturing remote offset points. This laser IMU RTK GNSS workflow reduces repeated receiver repositioning and helps improve productivity in complex field conditions. It is particularly useful where physical access is limited by traffic, vegetation, water, steep terrain, construction activity, or safety restrictions.
The updated i85 adds compatibility with CHCNAV PointSky L-band GNSS correction services. PointSky delivers real-time centimeter-level GNSS corrections via satellite, reducing dependence on a local base station, radio link, or NTRIP network service. This capability supports field teams working in remote locations where cellular coverage is limited, unstable, or unavailable. For topographic and remote infrastructure surveys, PointSky helps simplify field logistics by allowing surveyors to work with fewer setup requirements in the field.
