Recent studies of galaxies from the Sloan Digital Sky Survey (SDSS) show that small satellite galaxies are not distributed isotropically about their hosts. The standard practice of measuring the angular distribution of the satellites is limited by projection effects. I present a method that can overcome the effects of projection and can therefore identify the actual angular distribution of satellite galaxies. I apply this method to disk galaxies selected from the SDSS catalog and constrain the allowed angular distribution of satellite galaxies orbiting disk-like hosts. These results may be used to constrain the shapes of galactic dark matter halos if the distribution of satellite galaxies is correlated with the distribution of the dark matter.
