In July 2008, Yahsat approved a consortium of EADS Astrium and Thales Alenia to construct Yahsat's own satellites, whose manufacturing took 36 months to be completed in Europe. Arianespace were appointed to launch the first satellite Al Yah 1, currently positioned at 52.5° East.[4]
In August 2008, Yahsat signed a 15-year lease agreement with the UAE Armed Forces to provide secure satellite communications in the UAE as Yahsat's first government customer. As part of this contract, Yahsat will supply the ground terminals and gateway infrastructure for satellite network services.[5]
In August 2009, Yahsat entered into a partnership with European satellite operator SES to create a new company operating under the brand name YahLive, offering Direct-to-Home (DTH) television capacity and services to more than two dozen countries in the MENA region.[6]
In December 2023, the company announced that it would be merging with Emirati firm Bayanat to form a new company Space42, pending regulatory and shareholder approvals.[7]
In August 2024, in cooperation with Bayanat they launched the UAE's first SAR satellite that will enhance observations of Earth.[8]
