ISO 17123-5:2018规定了在建筑和测量中使用全站仪及其辅助设备时，在确定和评估坐标测量精度（重复性）时应采用的现场程序。这些测试主要用于现场验证特定仪器是否适合当前任务，并满足其他标准的要求。它们并不是作为验收测试或性能评估而提出的，本质上更全面。 这些现场程序专为现场应用而开发，无需特殊辅助设备，旨在将大气影响降至最低。

ISO 17123-5:2018 specifies field procedures to be adopted when determining and evaluating the precision (repeatability) of coordinate measurement of total stations and their ancillary equipment when used in building and surveying measurements. Primarily, these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task at hand and to satisfy the requirements of other standards. They are not proposed as tests for acceptance or performance evaluations that are more comprehensive in nature. These field procedures have been developed specifically for in situ applications without the need for special ancillary equipment and are purposely designed to minimize atmospheric influences.
