The metrological support of optoelectronic instruments for measuring spatial coordinates is described. In order to meet current consumer requirements for accuracy in measuring spatial coordinates with electronic total stations and their counterparts (laser scanners; absolute trackers), GET 199-2024 State primary special standard of the unit of length includes technical means of reproducing, maintaining, and disseminating the unit of length in three-dimensional measurement mode. A standard three-dimensional measurement system (coordinate measurements; coordinate increments) was developed and studied. The means and methods for disseminating the unit of length in coordinate (length) increment measurement mode are presented, as well as the metrological characteristics of GET 199-2024. The sources of the residual systematic error and the standard deviation of the measurement result were determined. The conducted study enabled a reproduction of the unit of length in the mode of measuring coordinate increments within the range of 0–60 m with the standard deviation not exceeding 25 μm at ten independent measurements and a residual systematic error (at a confidence level of 0.99) of 19 μm. The functional capabilities of GET 199-2024 will provide a means to solve relevant problems associated with the metrological support of high-precision electronic total stations and their counterparts in three-dimensional measurement mode.
