Instruments such as theodolites, tacheometers, total stations, laser scanners, laser trackers measure both horizontal and vertical angle values.
The vertical angle of three tacheometers (NIKON DTM352, Trimble 5605, Topcon DT9) were calibrated for testing purposes.
Additionally, same marks were measured using the tacheometer (1), thus introducing a single coordinate system both for photogrammetric and tacheometer measurements (Ruzgiene et al.
To have the point cloud of the entire wing section, the tacheometer was repositioned several times with two stabile points taken as reference.
3 and 4), both tacheometers produced deviations of measurements showing certain systematic errors of measurement (Typical curves), which could be eliminated from measures thus increasing the final accuracy of measurements.

The main objective of experiment was to test the calibration method and obtain preliminary results of the systematic errors (biases) of the vertical angle measurements using Trimble 5503 tacheometer.
The resulting calculated deviations of tacheometer readings are shown if Fig.
