Thuraya 1

 2000-066A

---

The Emirates Telecommunications Corp. of Abu Dhabi (Etisalat) contracted for the Al Thuraya comsat system for Middle East mobile telephony services and spun off Thuraya Satellite Telecommunications. Thuraya uses a Boeing Satellite Systems (BSS) Boeing 702/GEM (Hughes HS-GEM, GEO Mobile) model with large 12.25m, 78 kg L-band antenna, based on the HS-702 bus. Power will be 13 kW. Launch 2000 May by Zenit-3SL, with HSC turning over the satellite to Thuraya after 4 months in orbit. Problems with the system meant that Thuraya Satellite Comms finally accepted the overall system in Feb 2002.

Mass is 5108 kg launch. Span is 34.5m. Location 44E.

In 2003, it was planned to lease the satellite to Planetel (California) to provide mobile comms to Asia. It moved to 52E in Aug-Sep 2003 and then to 98E in Jul 2004.
