The main role of the ESA geostationary Artemis satellite is to relay data from low orbiting earth observation satellites to users in Europe. For this purpose Artemis has three data relay payloads: two payloads operating at microwave frequencies (S and Ka band) and one optical payload (SILEX). VTT Information Technology and Ylinen Electronics Co. deliver the Ka band in-orbit test station for the in-orbit testing of the Artemis Ka band payload. The characteristics of an in-orbit test station antenna must be known very accurately in order to perform accurate satellite in-orbit measurements. Hence, the antenna electrical and mechanical design, manufacturing, measurements and calibrations form a very challenging task.
