- Laser Tracking systems are commonly used in all branches of industry, which requires accurate large-scale measurements for instance aviation, space and shipbuilding industries. Laser Trackers belong to the group of non-Cartesian Coordinate Measuring Systems. Determination of the measured point coordinates involves the measurements of distance using laser beam and two angles recorded by horizontal and vertical encoders. Additionally, the environmental conditions are monitored and used for compensation of measured distance. The coordinates of single measured point are estimated using the results obtained from a series of samples taken in a short time period. The average value obtained from a sample is given as a result; additionally, the dispersion parameters are calculated which can be used to evaluate the probing process. This paper presents the research procedure which allows assessing the influence of chosen dispersion parameter related to the sample averaging on accuracy of the measurements performed with laser tracking devices. The procedure involves standard elements measurements during which the points with similar level of RMS parameter are used for the calculation of the measurement result. Such approach allows simulating the increasing dispersion of points taken into account during sample probing. The results presented in the article can be helpful to the operators of laser tracking systems to assess the influence of the probing process on the measurement accuracy.
