The new algorithm was proposed for the determination of total quantitative characteristics of 3 groups of errors, which effect within whole measurement cycle in leveling networks: 1) random errors, 2) systematic errors, 3) errors caused by the Earth’s surface deformations. The algorithm is based on recursive formulas. The technique was tested in the case of the Ukrainian State Leveling Network. It was determined from the last cycle of measurements (1971 - 1993) that the errors for 1 km of a leveling trace are the following: the random error - 0.49 mm, the systematic error - 0.06 mm, and the error caused by the Earth’s surface deformations -0.015 mm/year.
