Scientific paper

The paper presents the automatic time recording of transits of the image of a star across the hairs in the visual field of a telescope and the automatic reception of radio time signals for the determination of astronomical latitude and longitude of a station using an astrolabe. The automatization was achieved by an electronic calculator HP41CX and an especially constructed relay. The method proved very practical in the course of making the network of geoidal points more dense for the needs of geodesy.
