Swift Satellite (IMAGE) University of Copenhagen - Niels Bohr Institute Caption The Swift satellite has three instruments on board. They work together to get as much information about each gamma-ray burst as possible. The Burst Alert Telescope is a monitoring telescope, and the first to detect a burst. The X-ray telescope and the ultraviolet/optical telescope have a coordinated field of view, so the radiation can be observed in all three wavelengths together.
