Line 7:
The five satellites operate in three 500-kilometre orbits in planes roughly sixty degrees apart. They use an [[Radar#Frequency bands|X-band]] radar with a three-metre dish, providing a resolution of about 50 centimetres over a frame size of 5.5 km on a side ('spotlight mode', in which the satellite rotates to keep the dish pointed at a single target) or about one metre over a frame size of 8 km x 60 km ('stripmap mode', in which the satellite maintains a fixed orientation over the earth and the radar image is formed simply by the satellite's motion along its orbit). Response time for imaging of a given area is ten hours or less. [[Thales Alenia Space]] provided the core of the Synthetic Aperture Radar sensors.<ref name=thales-sensors>
