N2 - An Inter-Satellite Link Antenna (LISA), developed for transmitting data via a geostationary relay satellites is attached to a three degree of freedom satellite attitude simulator in order to validate not only the pointing mechanism of the antenna but also the algorithms on-ground. While the device is simulating a satellite orbiting in LEO the antenna will compensate the rotational motions and maintain a link to the ESA relay satellite ARTEMIS. This paper gives an overview on the efforts that have be undertaken to use real satellite data for testing the link maintenance of the inter satellite link antenna on-ground. For reproducing satellite attitude by means of a simulator with 3 rotational degrees of freedom an inter-satellite link based coordinate frame is not only introduced at the orbiting satellite and but also at the satellite on the simulator on-ground. This coordinate frame and related Euler angle conversions are the basis for obtaining angular data which is essential for the actuators of the simulator.
