Ground Segment: Transformational Antennas II – Will terminals realise the promised LEO Connectivity Revolution?

Thursday, 13 August 2020

3:00 pm UK time / 10:00 am US Eastern time

This is the second of two webinars which will take an in-depth look at the “antenna transformation” which the satellite industry – and its customer markets – has keenly anticipated for some time. Is this transformation the key to the realisation of the full potential of LEO (and MEO) technology and of the massive expansion of the satellite user market base it could enable?

For LEO (and MEO) satellite systems to maintain permanent contact with ground segment infrastructure, the antennas pointing at them – unlike the non-mobile fixed satellite service (FSS) installations in geostationary satellite links – have to track a given satellite and then frequently change the satellite to which they are pointing as the successive spacecraft of a constellation traverse the sky. Of course, tracking antennas are nothing new in the mobile environment of maritime and aeronautical communications over GEO satellites.

Form factor and low weight – as well as low aperture, high reliability and pointing accuracy – are major considerations for the mobility markets, and also for those facets of the IoT, and IIoT, that includes such developments as connected cars and commercial vehicles, the emergence of the “Smart City”, and automated industrial process and utilities monitoring.

Is there a single FPA solution that is a best fit for all current, and potential future, markets to be served by LEO (and MEO) satellites? Currently available, or in development, solutions take different approaches, offering technologies that can broadly be defined as: the mechanically-steered antenna (MSA), the electronically-steered antenna (ESA), and on the cutting-edge, the optical beam forming antenna.

This session will explore the direction the antenna transformation will take for the industry and its customers of non-geostationary orbiting satellites.
