The Ultraviolet Plume Instrument (UVPI) is designed to image and make radiometric measurements of rocket plumes, image and conduct earth background measurements, and gather earth background clutter data in the 200 to 450 nm region. The instrument will be one of several experiments in an earth orbiting satellite to be launched by the Naval Research Laboratory. The optical system uses a 10-cm aperture telescope with the image divided into two overlapping spectral regions, 200 to 360 nm and 250 to 450 nm. Four spectral filters isolate selected portions of the lower region for the plume camera and the upper region (i.e., 250 to 450 nm) is used primarily for tracking. Two intensified CCD cameras are used as sensors. Pointing and tracking capability for the UVPI system is provided by a two-axis gimballed mirror with supporting electronics and software. The instrument can be configured for a specific encounter by ground command, or can be completely autonomous through use of its own onboard computer and data recorder.
