Abstract:
1. An antenna system for driving a drivable antenna in at least one movement degree of freedom, comprising: a target value provider configured to provide at least one target value; a data-bus configured to relay the at least one target value; at least one antenna drive unit configured to drive the drivable antenna in the at least one movement degree of freedom according to the at least one target value, and including at least one sensor unit configured to provide a current position in the at least one movement degree of freedom for an internal control of the antenna drive unit, wherein the data-bus is constituted by a Controller Area Network bus, wherein the at least one antenna drive unit is constituted by an integral Controller Area Network bus based motor system, including integrally a transceiver configured to receive the target value relayed by the Controller Area Network bus and to decide the relevance of the target value based on the at least one movement degree of freedom; one of the at least one sensor unit being a positioning sensor further configured to detect a current motor state based on one of the at least one movement degree of freedom; and a motor configured to drive the antenna in the one of the at least one movement degree of freedom according to the target value received by the transceiver and the current motor state detected by the positioning sensor, and wherein the Controller Area Network bus is connected directly to the target value provider and the transceiver of the at least one integral Controller Area Network bus based motor system.
