An antenna for ship detection
An antenna for ship detection
Until now, satellites equipped with non-directional antennas have monitored maritime traffic, and the individual signals cannot easily be distinguished in areas with large numbers of vessels. For the AISat satellite, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has developed a four-metre-long helical antenna and a satellite receiver. The spacecraft will be controlled and operated by the DLR Institute of Space Systems in Bremen.
