Laser Tracker Spatial Coordinate Measuring Instrument

Zhongtu Instrument's GTS Laser Tracker Spatial Coordinate Measuring System is a high-precision, portable large-scale spatial coordinate measuring machine, serving as a high-performance photoelectric measuring instrument that simultaneously achieves high accuracy (μm-level) and a large working range (hundred-meter scale). It integrates laser interferometric ranging technology, photoelectric detection technology, precision mechanical technology, computer and control technology, and modern numerical calculation theory. It can be used for applications such as dimensional measurement, installation, positioning, calibration, and reverse engineering, making it a powerful metrology and inspection tool.

Application Fields

The GTS Laser Tracker Spatial Coordinate Measuring System can be widely applied in various large-scale spatial precision measurement fields, such as:

Measuring aircraft components and assembly accuracy in the aerospace industry;

Measuring flatness, straightness, cylindricity, etc., in the machine tool industry;

Online measurement of vehicle models in automotive manufacturing;

Precise calibration of robotic positions in manufacturing.

Additionally, the laser tracker can be extensively used in various advanced manufacturing fields, including shipbuilding, rail transportation, and nuclear power.

The GTS Laser Tracker Spatial Coordinate Measuring System, when used with an optical retroreflective target ball, forms a three-degree-of-freedom laser tracker capable of precisely measuring geometric features such as points, lines, surfaces, and curves in large-scale spaces. When paired with a spatial attitude probe, it forms a six-degree-of-freedom laser tracker that can rapidly and accurately measure complex features of workpieces, including internal features, hidden features, or curved surfaces, based on the precise spatial attitude of cooperative targets.
