YAHSAT 1A & 1B YAHSAT 1A is the first of two satellites that the Al-Yah Satellite Company (Yahsat), a subsidiary of a state-owned Mubadala Development Company from UAE ordered in 2007 from a consortium made up of EADS Astrium and Thales Alenia Space. The second satellite, YAHSAT 1B will be launched several months after YAHSAT 1A. Both satellites will be located at 52.5° East and they are Eurostar E3000 spacecrafts with a launch mass of 6 tonnes and an electrical power of 12 kW. The mission life of the satellites is 15 years and they will serve military and commercial purposes. Yahsat will use these satellites to offer broadcasting, broadband Internet and telecommunications services including telephony in the Middle East, Africa, Europe and South West Asia. YAHSAT 1A will have 21 Ka-band, 23 Ku-band and 14 C-band transponders (8 with 36 MHz and 6 with 54 MHz bandwidth). Yahsat 1B will only feature Ka-band payload. YAHSAT 1A will be launched into orbit aboard an Ariane 5 rocket, while YAHSAT 1B will be put into orbit on a Proton vehicle.
