Neutron Star Interior Composition ExploreR (NICER) is an X-ray telescope mounted on the International Space Station and includes the X-ray Timing Instrument (XTI) which has 56 elements that can measure both the energy and arrival time of X-ray photons to very high accuracy. This works together with the ISS' on-board GPS to perform detailed time analysis of pulsars among other things.
