Viasat said that its solid-state, fully-electronic phased array flat panel antenna has been selected by SES Networks for the O3b mPOWER satellite communications (satcom) system.
This flat panel antenna is described as a compact, lightweight solution for fixed and mobile broadband terminals. It is scalable, customizable and will enable SES Networks to target various types of users with different broadband connectivity needs.
Without any moving parts, the antenna can dynamically steer beams and rapidly follow a satellite’s position, allowing seamless handover between satellites in a non-Geostationary Satellite Orbit (NGSO) constellation.
The antenna is also said to feature 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.
