The Ultimate Corridor Mapping System

Survey-Grade (cm-level) accuracy with 250m+ laser range and outstanding intensity calibration on high altitude and high-speed missions.


The RANGER-ULTRA is an airborne laser scanner with an impressive combination of weight, range, accuracy and pulse rate. It is equipped with a unique forward and rear looking FOV designed to minimize laser shadowing and provide geometry on complex vertical structures on a single pass. With its wide field of view of 100 degrees and an extremely fast pulse repetition rate of up to 1.8 MHz, the RANGER-ULTRA is perfectly suited for high point density corridor mapping applications such as power line, railway track and pipeline inspection. 


  • Modular and upgradable for maximum project flexibility, supporting single/dual RGB, and multispectral cameras.

  • Easily mountable to unmanned platforms (UAVs) and to helicopters, gyrocopters, and other small manned aircraft.

  • Operating flight altitude up to 720 m / 2,350 ft.

  • Scan speed up to 400 lines/second.

  • 3 faceted mirror (-10, 0, +10°) creates a virtual multilaser for improved mapping of vertical surfaces.

Quick Specs:

  • Absolute Accuracy = 25-50 mm @ 350 m range.

  • Weight = 3 kg / 6.5 lbs.

  • Dimensions = 242 x 117 x 215 mm.

  • Pulse Rate = 1800 kHz, up to 15 returns.

  • Laser Range = 760 m @ 20% reflectivity.
