Morelos Satellite System
The Morelos satellites are a series of Mexican communications satellites. The first two operated between 1985 and 1998 and provided telephony, data, and television services over the territory of the Mexican Republic and adjacent areas. The third is now part of the MEXSAT constellation (sister ship of the MEXSAT-1 lost during launch) but carries the Morelos name.
