FIELD: agriculture.SUBSTANCE: invention relates to agriculture, in particular to locating an animal using radio waves. Radio signals transmitted between a node whose location is to be determined and nodes with a known location, and parameters measured during signal transmissions are used to calculate the distance between one or more nodes with a known location, on one hand, and the node whose location is to be determined, on the other hand, and/or the difference in the distances between the individual nodes with a known location and the node whose location is to be determined is calculated, and the calculation results are also used to calculate the possible positions of the node whose location is to be determined. Data processing system stores information about the height at which the node is located on the animal, whose location is to be determined. Assignment of the height assigned to the corresponding current type of activity of the animal is included as a limiting condition in the calculation of the locat
