 Calculated on the basis of their position, their elevation, and their compass (azimuth) angle, the antennae are generally orientated towards satellites of the INTELSAT, Intersputnik, and INMARSAT communications networks over the Atlantic Ocean, Africa, and the Indian Ocean, as well as towards the Middle East and mainland Europe.Somewhere between 2011 and 2013, a torus antenna was installed, which is able to receive the signals of up to thirty-five satellites simultaneously.This antenna is not covered by a radome.
