A portable 31 cm aperture f/1.3 Schmidt telescope with a CCD sensor at the prime focus has been designed and constructed to carry out photometric studies of earth-orbiting debris. When operated in the time delay integration mode in which the readout rate is matched to the predicted motion of the satellite, this system reaches a limiting diameter of about 10 cm for particles at 400 km height and albedo 0.1. It is used for statistical studies of phase angle effects and for swarm-to-swarm albedo differences between several selected debris groups which include the Cosmos 1275, Cosmos 1375, Landsat 1, Landsat 3, NOAA 3, Nimbus 4, Solwind, and Spot-1/Viking groups.
