Benefits and Performance

  1. 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.
  2. 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.
  3. 3D Modelling: The i93’s dynamic panoramic video capture, combined with drone data, enables easy 3D joint modeling of buildings and facades. Compatible with standard 3D modelling software offering flexibility and convenience.
  4. 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.
  5. 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.
  6. 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.
