Advanced IMU-RTK GNSS Receiver with Visual Surveying
Boosts 2.5 cm accuracy by 20%
Dual cameras capture survey grade 3D coordinates for efficient measurement
Centimeter-level GNSS positioning via L-Band where networks are limited
Capture dynamic panoramic video for 3D modeling
The i93 cameras provide an immersive 3D visual stakeout experience. With the 3D visual view, surveyors are guided by a clear, bold directional arrow and real-time distance to the stakeout point and lines marked directly on the ground.
The i93 quickly delivers survey-grade 3D coordinates from real-world video capture, making it easy to survey hard-to-reach, signal-obstructed, or hazardous points in the field—such as areas under overpasses, eaves, or near power poles.
By merging drone data with the i93's dynamic panoramic video capture, 3D joint modeling of buildings and facades is easily achieved. Compatibility with standard 3D modeling software provides flexibility and convenience.
The i93 includes one year of PointSky Service as standard. Delivered by satellite, it enables easy surveying where network coverage is limited or base station setup is difficult, delivering reliable 3 cm accuracy in only 3 to 10 minutes.
The i93 integrates a 1,892-channel GNSS receiver supporting GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS. Powered by CHCNAV's iStar algorithm, it maintains reliable multi-constellation, multi-frequency RTK positioning in challenging environments and achieves a fixed-solution rate above 96% during periods of high solar activity.
The i93 adapts to different GNSS surveying workflows as either an RTK rover or GNSS base station. Integrated 4G and UHF modems support network and radio RTK corrections, while Wi-Fi, Bluetooth and NFC provide flexible connectivity with field controllers and survey software.

Visual-LiDAR GNSS RTK receiver with consistent accuracy in obstructions
The i93’s dual cameras extract survey-grade 3D coordinates from real-world video, enabling precise measurements of previously inaccessible points.
The i93 supports GPS, GLONASS, Galileo, QZSS, NavIC/ IRNSS and BeiDou constellations, ensuring robust signal tracking and high accuracy.
CHCNAV PointSky provides centimeter level accuracy similar to traditional base and rover RTK solutions, usually within one minute in selected regions. Advanced PPP algorithms ensure stable positioning and repeatable results across different fields and seasons.
The i93 uses advanced GNSS signal processing and filtering to reduce the effects of multipath, interference and jamming. This helps maintain reliable satellite tracking and accurate RTK positioning in challenging surveying environments.
The i93’s 200 Hz Auto-IMU technology eliminates manual initialization, providing fast and accurate measurements with automatic pole tilt compensation.
The i93 measures 152 mm x 81 mm and weighs 1.15 kg, making it a robust and portable solution for field surveys.
The i93 provides up to 34 hours of RTK rover operation and up to 16 hours of RTK base operation with its 9900 mAh battery.
PointSky service positioning performance relies on the receiver’s continuous tracking of communication satellite signals. In obstructed environments such as dense urban canyons, heavy foliage, and tunnels, signals may be interrupted or attenuated, resulting in degraded positioning accuracy, service interruptions, or unavailability. For optimal performance, use in open-sky conditions is recommended.
Yes. The i93 operates as both an RTK GNSS rover and a GNSS base station. Its 9,900 mAh battery provides up to 34 hours of RTK rover operation and up to 16 hours in base mode, while integrated 4G and UHF modems support network and radio RTK corrections. For dedicated base station applications, CHC Navigation also offers the CHCNAV iBase GNSS base station.
The price of the CHCNAV i93 depends on your selected configuration. For detailed pricing and options, please contact CHC Navigation through the inquiry page.
