Patent ID: 7583373

Claim:
A geodetic total station for optical measurement of horizontal angles, vertical angles and distances to a target point a distance away, comprising: an upper part which is rotatable about a vertical axis and has a support with at least one support section; a sighting telescope which is arranged on the at least one support section and is rotatable relative to the support about a horizontal tilting axis and by which the target point can be sighted and the distance to the target point can be determined by electrosensory means; an electronic display control unit to which measured data acquired by electrosensory means are fed so that the position of the target point can be determined, optically displayed, and stored by the display control unit; at least one total station data interface having a data link to the display control unit and possessing electrical contact elements, for permitting a data link to at least one peripheral component; and a top attachment which is detachably coupled mechanically above the support and the telescope by at least one mechanical support interface arranged on the upward-pointing side of the at least one support section and at least one corresponding mechanical top attachment interface of the top attachment, wherein: the total station data interface is arranged on the upward-pointing side of the at least one support section; the top attachment comprises the at least one peripheral component and has at least one top attachment data interface which has electrical contact elements and possesses a data link to the peripheral component; and the mechanical support interface, the mechanical top attachment interface, the total station data interface, and the top attachment data interface are arranged and formed in such a way that the contact elements of the total station data interface and the contact elements of the top attachment data interface make mutual electrical contact by coupling the top attachment to the support section.
