Gogo and Phasor, a developer of innovative, modular, electronically steerable antennas (ESAs), have announced a research and development partnership for application of their technology to the in-flight connectivity market.
Michael Small, Gogo’s President and CEO, said: “Gogo is committed to offering our aviation partners a roadmap for the future that will bring the most bandwidth at lower costs to the aero market.
“Whether it’s satellite advancements, new modem technologies or best-in-class antenna technologies, our focus is on what’s best for aviation, and Phasor is developing ground-breaking satellite antenna innovations for the aero market.”
An electronically-steerable antenna uses beam-forming techniques between multiple elements to electronically move the beam onto the satellite.
By electronically changing the relative phase of the signal that each element transmits, the (constructive and destructive) combination of all of these small signals creates a larger focused beam in a particular direction.
These antennas therefore have no or few moving parts, which helps with reliability and maintenance.
The challenge is to make this type of antenna work well at high latitudes where the satellite signal is at a very oblique angle to the antenna.
Phasor’s very low profile, electronically-steerable antenna products are based on well-established semiconductor fabrication techniques, and enable signal tracking with no moving parts.
The antenna architecture is inherently modular, which allows the system to be scaled to various sizes and dimensions depending on the demands of the application, making this antenna technology particularly attractive for smaller aircraft.
David Helfgott, CEO of Phasor, said: “Gogo is a technology leader in the in-flight connectivity market, and we are very pleased to partner with them so that together we may address the burgeoning demand for communications in the aeronautical broadband sector.
“Phasor’s breakthrough technology is powerful and flexible and can therefore facilitate multiple in-flight connectivity applications. We look forward to working closely with the Gogo team to better serve this important and growing market.”
