The Viasat flat panel antenna will be used for a new generation of customer edge terminals for multiple applications on the O3b network.

Viasat’s flat panel antenna technology leverages years of commercial innovation and research and development (R&D) investment. For fixed and mobile broadband terminals, the flat panel antenna is compact, lightweight, scalable and customizable – enabling SES Networks to target various types of users with different broadband connectivity needs.

Viasat’s fully-electronic flat panel antenna has the ability to dynamically steer beams—without any moving parts—and rapidly follow a satellite’s position, allowing seamless handover between satellites in a non-Geostationary Satellite Orbit (NGSO) constellation. The antenna also features advancements in spectrum usage; dynamic interference mitigation to and from other satellites; enhanced processing power; and the ability to perform on-the-fly reconfiguration of antenna characteristics to enable end-terminals to support and communicate within a hybrid satcom system of NGSO and Geostationary Satellite (GEO) systems.

The Viasat phased array is based on proprietary flat panel core technology, inclusive of a new RFIC and a modular approach that enables multiple types of user terminals — from residential broadband and in-flight Wi-Fi to connected car and backhaul applications — to keep pace with growing broadband connectivity demands. The current phased array uses a dual-beam flat panel antenna system operating in the full Ka- frequency band with an ability to be customized for Ku-band applications. The development of the Viasat phased array is in part supported by the European Space Agency (ESA), through a Public Private Partnership (PPP) Viasat and ESA announced in November 2017.
