CHCNAV i85 Pocket Laser IMU-RTK GNSS
The i85 Pocket Laser RTK is an ultra-compact, lightweight solution designed for high-precision surveying in demanding environments. Featuring integrated GNSS, IMU, dual cameras, and a laser module, it enhances stakeout workflows by up to 40% through intuitive CAD and AR-based visual guidance, and measurement workflows by up to 50% through laser measurement.
GNSS Sensors
High-Precision GNSS for Surveying Accuracy
Consistent centimetre-level positioning, even in challenging environments.
Powered by CHCNAV’s multi-constellation, multi-frequency GNSS chipset and iStar2.0 technology, the i85 provides reliable, centimetre-level accuracy even in built-up or obstructed environments. An advanced IMU further enhances heading accuracy, ensuring confidence in every measurement.
Laser Measurement with Extended Range
Capture inaccessible points quickly, safely, and with precision.
The i85 integrates a high-precision laser, enabling measurements accurate to ±2 cm at 5 m and ±3 cm at 10 m. Surveyors can capture points across rivers, behind barriers, or in hazardous locations without direct access. This hybrid GNSS + laser solution cuts data collection time by over 50%.
Built for Demanding Site Conditions
Durable, stable, and reliable in any surveying environment.
With a reinforced metal chassis and stable all-in-one design, the i85 maintains precise laser alignment in tough environments. Intelligent gain control adapts to lighting and signal conditions, while a temperature sensor fine-tunes algorithms for consistent accuracy across varied site conditions.
Safe, Efficient, and Reliable Data Collection
Hybrid GNSS and laser technology for safer fieldwork.
By combining robust GNSS positioning with laser measurement, the i85 ensures surveyors can work safely and productively, even under tree cover, near tall structures, or in areas that pose safety risks. It delivers trusted performance where conventional GNSS receivers struggle.
he i85 supports GPS, GLONASS, Galileo, and BeiDou constellations, ensuring robust signal tracking and high accuracy.
The built-in laser range finder extracts 3D coordinates through precise aiming, enabling accurate measurement of inaccessible points.
Yes, the i85 is IP68-rated for dust and water resistance and can withstand a 2-meter pole drop, ensuring reliable performance in a variety of field conditions.
The i85 operates for up to 20 hours on a single charge and supports Type-C power input for use with power banks or vehicle chargers.
In typical application, laser survey accuracy can reach 2 cm at 5 m distance, and 3 cm at 10 m distance.
