The Redu site, which hosts multiple ground stations, is located in the Ardennes region of Belgium, about 1 km from the village of Redu which is in the Belgian province of Luxembourg. The stations provide tracking capabilities in VHF, C-band, L-band, S-band, Ku-band and Ka-band, and provide in-orbit tests (IOT) of telecommunication satellites. The S-band station is presently used for W3 (Eutelsat). The next ESA Science project to use the S-band station is Integral.
The station co-ordinates, measured at the brass plate on the interferometer patch are 5.146231°E longitude, 50.002685°N latitude.
This reference point is 378.3 m above sea level. The co-ordinates of the TMS-1 antenna are 5.14518047°E longitude, 50.00205516°N latitude. The antenna is sited at 385.583 m with respect to the WGS-84 reference ellipsoid [2]. The geostationary visibility above 10° elevation, is between 54.9°W and 65.1°E.
