Satcom Future Hinges on Electronically-Steered FPAs - NSR Mar 2019
"When the term “flat panel antenna” (FPA) is mentioned, most envision a completely flat, non-moving piece of communications technology. These systems, specifically electronically-steered antennas (ESAs), capable of faster tracking and pointing than parabolic ones, are seen as an impending necessity for satcom, especially given the soon-to-be full skies of LEO constellations. Interest and development in this technology has grown significantly in recent years, from Kymeta shipping the first commercial ESAs in 2017 to large contracts signed, pending product release.

However, ESA technology is still under-developed, mostly unavailable, expensive to engineer and suffering numerous delays. Currently, only 4 manufacturers (Kymeta, hiSky, SatCube, and SatPro) have ESAs for broadband-via-satellite available on the market, and given the importance of this technology for LEO networks, one wonders just when will this technology take off, and what happens if it does not?"

"NSR’s Flat Panel Satellite Antennas, 4th Edition report forecasts the market to transition strongly after 2020, with ESAs accounting for 97% of FPAs shipped in 2028. While mechanically-steered antennas (MSAs) currently dominate the FPA market, at 95.5% of shipped units, non-GEO networks, competition, and improved technology are expected to strongly pivot market take-up once LEO constellations are launched and operational. However, MSAs have begun to make successful inroads, and in some cases are expected to continue to provide competition to ESAs even after the technology becomes more available."
