SBS-2

 1981-096A


The second Satellite Business Systems spacecraft, SBS 2, was launched by Delta in Sep 1981 and stationed at 97W, three degrees from SBS 1. After being owned by MCI from 1985 to 1987, it was bought by Comsat. In 1983 it moved to 104W temporarily (from Jan to Mar). In 1988 the satellite moved to 99W, and back to 97W in late 1990. In Jan 1994 SBS 2 started a slow drift to 71W, arriving in October.
