EGNOS SBAS Host acquired by Telecom Company – Inside GNSS


Viasat Inc., a global communications company, will acquire Inmarsat, a global mobile satellite communications service provider, in a transaction valued at $ 7.3 billion. Two of the four broadcast payloads of the European Geostationary Overlay Navigation Service (EGNOS), part of the European GNSS, board the Inmarsat satellites, Inmarsat 4F2 Emea | PRN number 126 and Inmarsat 3F2 AOR-E | PRN number 120. In previous decades, Inmarsat satellites also hosted payloads for the United States Large Area Augmentation System (WAAS). Inmarsat was established in 1979 by the International Maritime Organization (IMO) to provide reliable safety satellite communications.

The combination will create a global communications innovator with enhanced scale and reach to connect the world affordably, securely and reliably. The additional assets and resources of the new organization will enable the availability of new advanced services in the mobile and fixed segments, providing customers with greater choice in broadband communications and narrowband services, including the Internet of Things. objects (IoT).

The combined company intends to integrate the spectrum, satellite and terrestrial assets of the two companies into a high-capacity global hybrid space and terrestrial network capable of delivering premium services in the fast-growing commercial and government sectors. . This advanced architecture will create a framework incorporating the most favorable characteristics of multiband and multi-orbital satellites and land-based air-to-ground systems that can deliver higher speeds, more bandwidth, greater bandwidth density in high-demand locations. demanded like airports and shipping. hubs and lower latency at a lower cost than either company could provide on their own.

The merged company will be able to offer:

• A large portfolio of spectrum licenses in the Ka, L and S bands and a fleet of 19 satellites in service with 10 additional satellites under construction and scheduled for launch over the next three years.
• A global Ka-band footprint, including planned polar coverage, to support bandwidth-intensive applications, complemented by L-band assets that support all-weather resiliency and highly reliable connectivity, at narrowband and IoT.
• The ability to unlock more value from Inmarsat’s L-band spectrum and existing space assets by incorporating Viasat’s beamforming, end-user terminal and payload technologies and its multi-hybrid network capabilities. -space-terrestrial orbit.
• Viasat’s highly vertically integrated technology and service offerings, as well as Inmarsat’s broad technology, manufacturing and service delivery ecosystem.
