In 1987 it was moved to 129° West, where it operated until it became unusable for meteorological studies in 1989. After ceasing operations as a weather satellite, GOES-3 was reassigned for use as a communications satellite. In 1990, it was relocated to 175° West, and in 1995 it was moved again, and was stationed between 102° and 110° West since 1996.
