Thuraya Module

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 heavies commercial payload ever launched and 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 Thurya 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 ge0-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 optimizes performance over high demand areas.

Thuraya’s satellite 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 optimizes over change in traffic demand)
