Thuraya Satellite |
| A Superior Mobile
Satellite System |
| Thuraya-1 satellite was launched on 21st
October 2000; on board a Sea Launch Zenit-3SL rocket from
the equator in the middle of the Pacific Ocean .It was
the heaviest commercial payload ever launched and the
first commercial satellite to employ digital beam forming.
Thuraya's commercial services began in a gradual roll
out in a number of countries in 2001. |
| |
| Thuraya's second satellite Thuraya 2 was
launched on the 10th of June 2003 while a third satellite
is being built by Boeing Satellite Systems to expand system
capacity. |
| |
| The Thuraya mobile satellite system is a
turnkey project built by Boeing Satellite Systems, formerly
Hughes Space and Communications International, Inc. (HSCI),
at the cost of US$ 1 billion. Designed for a 12-15 year
lifespan, the Thuraya 2 satellite is positioned in Geosynchronous
Orbit, 35,786 km (22,236 miles) above the Earth, at 44
degrees East Longitude and inclined at 6.3 degrees. The
contract includes manufacture of two high power geo-synchronous
satellites, the launch of the first satellite, manufacture
and installation of the ground network equipment, the
manufacture of nearly a quarter of a million mobile handsets
and the project insurance. |
|
|
|
| Thuraya's system has been adapted for efficient operation
in both satellite and GSM environments. It provides high flexibility
in managing network resources through a re-programmable satellite
payload. This supports modifications to the system's coverage area
even in the post-launch period and optimises performance over high
demand areas. |
| |
| Thuraya's satellites have been specially designed to
achieve network capacity of about 13,750 telephone channels. Thuraya's
hand held mobile terminals are comparable to GSM handsets in terms
of size and appearance, as well as in voice quality. |

| Satellite features |
| |
| 250-300 spot beams |
| Digital beam forming (which provides for dynamic area
coverage and optimises over change in traffic demand) |
| Single hop link for mobile-to-mobile communications |
| High power capacity |
| Dynamic satellite power control providing 10dB link margins |
| The Thuraya system is comprised of three key elements
- Space Segment, Ground Segment and User Segment. |
