Kyviskes Calibration Baseline is the longest calibration baseline in the Lithuania. Kyviskes Calibration Baseline was established by the Institute of Geodesy, VGTU in 1996 for the calibration of EDM instruments. Finnish Geodetic Institute together with Institute of Geodesy, VGTU are measuring Kyviskes Calibration Baseline regularly. The same Kern Mekometer ME5000 EDM instrument was used for all measurements performed. The Kyviskes baseline was converted to a triangle-shaped test field in year 2000, and three cycles of remeasurements were made in 2001, 2007 and 2008. Analysis of baseline calibration results of the baseline is performed and presented. The results of the baseline length are air temperature correlated. Possible reason for this are analyzed. Kyviskes Calibration Baseline became a test field for the different purposes after building seventh observation pillar. Kyviskes Calibration Baseline is the length standard for Lithuania and is used by Calibration laboratory regularly. The results confirm the good stability of the baseline, which is now used for calibration of EDM instruments and testing of total stations and GNSS measurement equipment.
