Scope
GB/T 45798-2025 is the English-translated version of 光电测量 激光跟踪测量系统性能检测方法.
GB/T 45798-2025 is the Chinese national standard covering how a laser tracker is checked before it is trusted to measure a large assembly — the interferometer and the absolute distance meter, each with its own ranging accuracy and range, the target tracking speed and acceleration beyond which the beam is lost, the spatial length measurement accuracy against a reference length, the attitude angle accuracy for six-degree-of-freedom systems, the laser safety and environmental conditions, and the test report. It covers three-degree-of-freedom and six-degree-of-freedom systems working out to a radius of 160 m. First edition, under the Chinese Academy of Sciences. In force from 1 February 2026. Issued on 1 August 2025, it has been in force since 1 February 2026.

GB/T 7247.1
3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
A measurement system that tracks a target using a laser beam and determines its position coordinates by distance (polar diameter) and two angles.
Note 1.The two angles are called horizontal angle (rotation around the vertical axis, i.e. the vertical axis of the laser tracking measurement system) and vertical angle (angle with the horizontal plane, the horizontal plane).
perpendicular to the vertical axis).
Note 2.The target attitude angle is measured by combining the attitude angle measurement accessories.
3.2 Laser interferometer
The laser interferometer measurement unit built into the laser tracking measurement system is used to measure the target distance (polar diameter).
Note. Laser interferometer is used to measure distance difference and has a reference distance (starting point).
3.3
Absolute distance measurement unit built into the laser tracking measurement system.
Note. The absolute distance measurement unit is used for target distance (polar diameter) measurement and to provide a distance reference after light interruption and reconnection during laser tracking measurement.
3.4 [Source. GB/T 16857.10-2022, 3.5, with modifications]
A reflective target fixed in a spherical shell.
Note 1.A reflective target is a passive reflector that can parallel reflect incident light within the acceptable range and is the cooperative target of the laser tracking measurement system.
Note 2 to entry. For an open corner cube, the vertex is usually adjusted to coincide with the centre of the sphere.
NOTE 3 The tests in this document generally use spherical targets.
