Ground stations tracking ISO
The Science Operations Centre at ESA's Satellite Tracking Station at Villafranca (Spain) was responsible for the control of the satellite. This is also where observations were scheduled. However, for scientific use ISO needed to be in continuous contact with a ground station. NASA's station at Goldstone (US) tracked ISO when it was obscured from Villafranca by the Earth.
