Description

The FUV instrument takes 2D images of the Earth’s horizon in the Far ultraviolet. The imager is pointing approximately 90 degrees to
the spacecraft motion, similar to looking out of the side window of a car as it drives down the road. Onboard electronics read the image
8 times per second and perform Time Delay Integration (TDI) to remove the motion-blur from the images. A turret is used to steer the field
of view of the instrument left to right to ensure it always looks along the magnetic meridian (towards the magnetic pole). The acronym "SWP"
(Short Wavelength Prime) capturing 1150 angstroms – 2000 angstroms emissions.
