The Ariane placed the Satmex 5 satellite into a 211km x 21516 km x 7.0 degree orbit from which the satellite was to use its on-board engine to reach geostationary orbit. Satmex 5 was operated by Satellites Mexicanos S.A. de C.V, which took over the Morelos constellation from Mexican Secretaria de Comunicaciones y Transportes. Satmex 5 replaced Morelos 2 and carried the XIPS ion engine station-keeping system.
