Paper Abstract

Hubble Space Telescope (HST) moving target observations are planned using the 'Percy' interactive computer program. Percy provides ephemeris and geometrical even information about solar system objects including the Sun, major planets and their natural satellites, comets, and asteroids. While Percy contains some HST specific feature, it should be useful for almost nay ground or spacecraft based observing system. Percy was originally developed by JPL, but the Space Telescope Science Institute took-over all Percy development in 1992. Since then, extensive modifications and many new features have been added. This paper reflects the current state of Percy.
