Description and Purpose: The Mexsat program is an end-to-end satellite communications system consisting of three satellites, two ground sites, associated network operations systems and 67 reference user terminals. Mexsat is México’s next-generation telecommunications system.
Customer: Secretaria de Comunicaciones y Transportes de México (Secretary of Communications and Transportation of Mexico)
General Characteristics: Representing a fourth generation of Boeing satellites to serve México, the Mexsat system will join the country’s current satellite fleet to offer mobile satellite services and fixed satellite services to support national security, civil and humanitarian efforts. The Mexsat system will provide disaster relief, emergency services, telemedicine, rural education, and government agency operations, including offering telecommunications access for the Mexican people living in remote parts of the country.
The Mexsat contract calls for Boeing to design and deliver a complete end-to-end turnkey system consisting of: two Boeing 702HP geomobile satellites; a GEOStar-2 satellite from Orbital Sciences Corporation for fixed satellite services; two ground stations; and ground-based beam-forming and communications network equipment. Boeing will also deliver reference user terminals, which are used for testing and validation of the system.
México named the three satellites: Bicentenario, to commemorate the anniversary of México’s independence from Spain; Centenario, in honor of the 100th anniversary of the Mexican Revolution; and Morelos-3, to continue the naming tradition of the first Mexican satellite system. The satellites will operate over México and its patrimonial seas, including the Gulf of Mexico and the Pacific Ocean.
Under a contract with Boeing, Orbital Sciences Corporation manufactured Bicentenario, a fixed system satellite that launched aboard an Ariane 5 rocket on December 19, 2012. Bicentenario is in service and operated by Mexico’s technical agency Telecomm.
The two ground stations in support of the Mexsat satellite system and network operations, located in Iztapalapa and Hermosillo, México, were unveiled in November 2012. Iztapalapa successfully completed the gateway site acceptance test in October 2013. The Iztapalapa ground station serves as the spacecraft operations center for network management and operation.
The Centenario and Morelos-3 satellites are Boeing 702HP geomobile satellites. Centenario, which was completed in 2013, is scheduled to launch on a Proton launch vehicle in 2014. Morelos-3 is scheduled for completion in 2014 and launch in 2015 on an Atlas V launch vehicle. Each 702HP satellite will supply 14 kilowatts of power through 5-panel solar array wings using high-efficiency ultra triple-junction gallium arsenide solar cells. Each spacecraft will carry a 22-meter L-band reflector for mobile terminal links, complemented by a 2-meter Ku-band antenna. Both Boeing-built satellites are designed for a 15-year service life.
Background: The Mexsat regional mobile satellite system builds on Boeing’s 14-year history of designing and delivering advanced geomobile satellite communications systems, including the Thuraya satellite system for Thuraya Telecommunications Co., LTD in the United Arab Emirates. Boeing became a satellite industry pioneer when it launched Syncom, the world’s first geosynchronous communications satellite, in 1963.
