Antenna Innovations: Keeping Up With The Rest of the Industry?
Thursday, 24 June 2021

The latest webinar in the GVF-SEG series begins with this very important question, one based on a very important premise – that the transformation of the commercial exploitation of space and rapid progression from “Space 2.0” to “Space 3.0” (exemplified in such innovations as re-usable and 3-D printed launchers, assembly line satellite manufacturing, terabit-per-second satellite networks) can only be fully realised if comparable innovations occur with antennas.
Antenna innovations in performance, cost, and operation may perhaps be less attention-grabbing than launcher stages softly landing after yet further successful orbiting of multiple satellites, but are no less transformative. Electronically Steered Antennas (ESAs) are just one example of the increased capacity, and even greater future potential, of the satellite terminal to provide vital communications links.
In this discussion, moderated by Jeremy Rose of COMSYS and featuring panellists representing some of the leading voices in the antenna world – Kymeta, INSTER, AvL Technologies, and ANYWAVES – the objective was to inform a global audience as to whether, or not, the antenna industry is keeping pace with other segments of the satellite communications industry.
Discussion began with a request made of the Kymeta representative: To explain the notion of the “disadvantaged antenna”, seemingly a rather novel term – related to the challenges of the technological drive towards small electronically steerable antennas (ESAs) – requiring significant clarification. That clarification was fascinating, prompting a energised following dialogue which, if you missed the live event, you can still enjoy by watching the video the link to which is available here.
Later questions covered differences in the performance and price requirements of high-end ESAs versus those of consumer units; requirements for antennas communicating with NGSO satellite constellations; panellists’ perspectives on the headline-grabbing Starlink antenna; and, what the panellists would like to request of satellite operators to help render more effective and efficient antenna design processes. This was an illuminating dialogue, so don’t miss it,… and miss out.
Q & A continued….
The following question was posed through the chat function during the panel but we ran out of time to respond in the live programme. Thank you to our audience for taking an active part by asking questions, and to our panellists for their time to answer them after the webinar ended… (Please note more questions and answers will appear here as we receive them from the panellists)
1. Richard talks about smaller antennas, so less gain available, so to maintain the link more/higher power PAs are needed. Power/heat has always been an issue with active antennas, so how is this going to be resolved?
Richard Hadsall (Kymeta): The additional power we see would be coming from the Satellite transponder. Where the Small antenna requires more PEB (Power Equivalent Bandwidth) from the satellite then does a parabolic. The ESA heat issue is more commonly found in active Phased Array antennas then in the Passive meta material antennas such as the Kymeta.
2. Hi, I enjoyed your discussion, lots of points I’ve noticed. I need clarification, on this. “Do you know how to testing and calibrating satellite antennas using unmanned aerial systems?”
GVF: GVF has experience with the testing and calibration of satellite antennas using UAS in as much as, in partnership with our member QuadSAT, based in Denmark, we successfully delivered on a joint project which also arose out of the work of the GVF’s Mutual Recognition Arrangement Working Group.
QuadSAT is developing a novel approach for conducting on-site antenna verification using UAS, or drones. This has been acknowledged by satellite operators as a valuable alternative to the traditional methods of testing. Use of a transportable airborne platform avoids the need to ship the test antenna to a remote location such as an outdoor far-field antenna range compact range/near-field test facility.
The European Space Agency (ESA) recognised the potential value of this technology and awarded QuadSAT a contract to develop and validate the technology with support from GVF. The Satellite Operators Minimum Antenna Performance (SOMAP) recommendations were used to compare performance data acquired by drone measurements with comparable test data acquired from a traditional far field outdoor test range.
The panel discussion focused on examining the many dimensions of space sustainability and the possibility that the world may soon pass the point where space sustainability is seriously threatened. Moderated by Victoria Samson of the Secure World Foundation, the moderator and panellists noted the significant increase in orbiting satellites and the increased risks associated with…
Panel discussion focused on examining the risks and returns of NewSpace which has attracted many millions of dollars of investment premised on the belief that companies starting in the segment will ultimately generate profits, attracted a diverse international audience. The glorious rise of space SPACs was the starting point of the dialogue, analysing where these…
Today’s webinar, a lively and informative 70-minutes of moderated dialogue, began with an overview of the factors contributing to the satellite industry’s drive to catch-up with other telecoms segments in its cloud adoption, together with an exploration of the advantages of incorporating the cloud into satellite businesses. Throughout the wide-ranging cloud computing-related discussion which encompassed…
The GVF Quarter Century of Excellence Award finalists have been chosen… and now they have spoken. The executives with the five finalists selected for their 25-years of contributions to the industry and the world, all of them recognised as industry leaders, presented their company’s case for being judged the “Best of the Best”. A representative…
GVF and Connectivity Business News presented ‘Innovation and the Ground Segment’, an hour of wide-ranging, free- and fast-flowing interaction between moderator and our panellists from across the satellite ground segment. As moderator, Tim Farrar set the scene with an insightful preamble, beginning with observations which in part noted, “Often the prevailing sentiment in the satellite…
