The Carlson CRT Robotic Total Station is a high-precision, Android-based instrument built for surveyors who require speed, accuracy, and dependable performance in the field.
Featuring advanced TDrive motor technology, the CRT delivers ultra-fast rotation speeds of up to 180° per second with smooth, gearless movement for quieter operation, reduced maintenance, and reliable high-speed prism tracking — even on moving targets.
Designed for professional-grade results, the CRT offers:
1 mm + 1 ppm accuracy with prism
Measurement speeds of less than one second
Up to 1000 m reflectorless range (800 m for 2″ model)
Up to 6000 m with a single prism
Available in 1″ and 2″ angle accuracy models
Its dual-axis tilt compensation and advanced EDM technology ensure consistent, millimetre-level accuracy across long distances.
Running on a built-in Android operating system with a 6″ colour touchscreen, the CRT provides a familiar, intuitive interface with onboard software and online capability. When paired with Carlson SurvPC, it supports hybrid workflows including GPS Search, GNSS integration, and prism measurement on tilted poles.
Engineered for durability, the CRT features IP65/IP66 environmental protection, operates from -20°C to +50°C, and includes dual Li-ion batteries for extended field use. Integrated 4G, Bluetooth, WLAN, RS-232, and USB connectivity ensure seamless data transfer and communication.
The Carlson CRT combines high-speed robotic tracking, long-range reflector less measurement, and intelligent Android-based functionality — making it a powerful solution for surveying, construction layout, and engineering applications.
