The antenna's design

The antenna uses an innovative design known as an electronically steered phased array. Rather than relying on a single large antenna that physically moves to track satellites, it uses many small components. These individual elements coordinate the timing of their signals to have a unified connection, similar to how a stadium wave forms as each person stands up consequently. This mirrors movement and provides not only a faster way to connect, but also the possibility of connecting to two satellites simultaneously.

Viasat’s in-flight solution’s commercial service is expected to begin in 2028. Thanks to its modular technology, the product can be easily incorporated into existing antennas, making it cheaper and easier to incorporate in passenger airlines.

“Phased array antennas are an evolutionary and much needed step towards more energy and space efficient in-flight connectivity solutions, and we are proud to have contributed to Project Aidan – a key milestone that led Viasat to developing Amara. We’re looking forward to next opportunities for cooperation with Viasat, and many other industry partners – for the benefit of all ESA Member States,” said Massimiliano Simeoni, Aidan’s Project Implementation Manager at ESA Connectivity and Secure Communications.

“The Viasat Aera terminal is a key part of Viasat Amara, our next generation in-flight connectivity solution going far beyond fast and free high-speed Wi-Fi,” said Viasat on its Viasat Amara announcement. “Our pioneering mission remains to help our airline customers maximize connectivity’s enormous potential for brand, loyalty, and growth. It's been great to work with ESA as one of our key partners to help bring it to fruition.”

This antenna development marks the beginning of exciting opportunities for the future of onboard connectivity.
