Message from CEO

APSI, the leader in domestic and overseas mobile communications
We will give our all as we grow into a world-class company specializing in satellite communication



Since the foundation of APSI, we have been dedicating our time and energy in discovering everything there is to know about satellites. With perseverance and hard work we have proven our competence by successfully creating UAE Thuraya’s second generation satellite mobile phones within a few years and still manage to grow everyday. By leveraging our remarkable execution of next generation core Tetra technology development projects, our company continues to produce Tetra portable Terminals and applied products, as well as conduct satellite communications services (common carrier).

We are breaking new ground as we release handy sized satellite communication modules that work as an advanced substitute for ground mobile phones. We are also taking in charge of not only producing but also conducting sales for products that apply all types of MSS(Mobile Satellite Service) technology, new generation Tetra high-speed data modems and portable Terminals for both satellite and Tetra, an optimal solution for disaster management.

APSI is the leading figure in the domestic and international satellite communications service business, contributing more and more in strengthening the communications technology. We are doing our very best to make changes in the global satellite communications field and to exceed what has already been introduced and expected for the future. In the near future we wish to bring out more innovative technology so that we can represent our country and create a unified world with our telecommunications system.


Thank you
