Benefits and Performance
- AR Visual Stakeout: The i93’s cameras offer an immersive 3D visual stakeout experience. Surveyors are guided by a clear, bold directional arrow and real-time distance to the stakeout point, with lines marked directly on the ground for precise positioning.
- 3D Visual Surveying: The i93 quickly captures real-world video and delivers survey-grade 3D coordinates, making it easy to survey hard-to-reach, signal-obstructed, or hazardous points, such as areas under overpasses, eaves, or near power poles.
- 3D Modeling: The i93’s dynamic panoramic video capture, combined with drone data, enables easy 3D joint modeling of buildings and facades. Compatible with standard 3D modeling software offering flexibility and convenience.
- Auto-IMU Technology: The i93’s Auto-IMU provides simple and reliable pole tilt compensation, delivering accuracy to within 3 cm over a 60-degree tilt range without manual initialisation.
- Superior GNSS Performance: Experience unmatched GNSS performance with the i93’s 1408-channel receiver. Supporting GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS constellations, the iStar2.0 algorithm provides over 96% reliable fix rate in areas of high solar activity.
- Versatile Field Use: The i93 offers all the connectivity features a surveyor needs with built in Wi-Fi, Bluetooth, and NFC technologies ensuring seamless connections to field data controllers and also integrated 4G and UHF modems support all GNSS RTK surveying modes.
Use Cases
- Topographic Survey
- Boundary Survey
