WebJul 11, 2015 · SBUV looks only at a 200 km square field of view directly beneath the spacecraft. The imaging instruments, OMI and OMPS, project an entire strip of the Earth onto a charge-coupled device (CCD) detector. As the satellite moves, this strip maps out the Earth. This is known as a push-broom system.
