Description
descriptions
The Leica TDRA6000 Laser Station is a portable inspection system designed for precision measurements on extremely large structures. It has an operational volume of 600 meters measuring 3D coordinates both with standard reflectors, and non-contact (reflectorless). The Leica TDRA6000 sets a new standard for ultra large scale metrology.

Direct Drive Technology
The all new Leica Geosystems proprietary direct drive technology has been designed from the ground up for the TPS6000 and the AT 402 family of sensors. Based on piezo technology, these new direct drives enable high speed motorization and acceleration, at up to 4x our previous generation, but still allow sub-micron level fine positioning. This revolutionary piezo technology has very low power consumption and because there are no gears, the drives require almost no maintenance, and are near silent.
Tracking Ability
A new high speed absolute angle encoder paired with our 4th generation Automatic Target Recognition (ATR) technology give the Leica TDRA6000 Laser Station the best tracking performance in its class. This new quadruple angle detection system is accurate to 0.5 Arc Seconds (1σ). The ATR and encoder feedback loop has been optimized for use with 1.5” corner cube reflectors and is specially tuned for use in a 600m volume.
Non-Contact Measurement
The Pinpoint Reflectorless Distance Meter allows non-contact measurements within the full 600 m volume, and has a very small visible beam that allows precision measurements on difficult surfaces. This new EDM is based on our proven System Analyzer technology that takes advantage of both phase and time-of-flight information. The System Analyzer accuracy is further enhanced (specifically on corner cube reflectors) by passing the laser beam through a new anamorphic lens. This lens reshapes the beam with an optimized profile and footprint allowing the inhomogeneous peripheral light to be cut off from the laser beam completely.
