MEASAT-3 is a Malaysian communications satellite which was successfully launched on 11 December 2006 from the Baikonur Cosmodrome in Kazakhstan.[1]
In March 2003, MEASAT Satellite Systems Sdn. Bhd. of Malaysia ordered a Boeing 601HP satellite, giving it the designation MEASAT-3 at that time. MEASAT-3 joined the existing Boeing-built MEASAT-1 and MEASAT-2 spacecraft in the Malaysia-East Asia Satellite (MEASAT) system.
International Launch Services (ILS) was contracted as the launch provider. Boeing was specified to also provide an upgrade to the MEASAT ground facilities in Malaysia, as well as training and launch support services.
MEASAT-3 was by International Launch Services using a Proton-M rocket with a Briz-M upper stage. The upper stage made five burns to place MEASAT-3 into a geostationary transfer orbit. After circularisation and testing, the satellite entered commercial service on January 25, 2007, in geostationary orbit at a longitude of 91.5 degrees East where it is co-located with MEASAT-1. The C band and Ku band now covers geographically remote areas such as Sabah, Sarawak, and North India and expands the MEASAT fleet's coverage to more than 100 countries embracing Australia, Middle East, Eastern Europe and Africa.
