The 32nd annual SATELLITE Conference and Exhibition took place last week (March 18-21) at the Walter E. Washington Convention Center in Washington, DC. Organizers were projecting that 12,000 satellite communications professionals from 70 countries would attend this year's event featuring a world-class conference program led by 300 satellite communications power players and more than 16 hours of networking opportunities over the four day gathering. The conference which serves multiple vertical markets including military/government, commercial, broadcast, maritime, mobility, and telecommunications shaping today's satellite-enabled communications landscape drew a large eco-system of delegates and exhibiting vendors: from single RF/microwave component manufacturers to full-platform providers.

With greater demand for global access to high-def content and recent improvements in launcher technology and the resulting decrease in cost (launching a given payload is one-third the cost during the 1980’s), there has been considerable activity and innovation in this market. As a result, space qualified hardware manufacturers see a number of opportunities thanks to the lower cost of putting hardware into orbit and promising technologies such as High Throughput Satellites (HTS)  leading to competition between systems operating at various frequency bands (Ka and Ku), each vying for the hearts and minds of component and platform manufacturers alike.

Over 350 exhibiting companies were on hand to showcase their latest and greatest emerging technologies in the satellite-enabled communications marketplace. With Washington mired in sequestration, a few exhibitors voiced concern over a notable decline in attendance from the highly-prized visitors from the DoD, NSA, CIA, etc that usually attend this event in relative droves (not drones). And yet by the second day of the exhibition, uniformed members of the armed services were increasingly more visible and the mood seemed to improve with the quality of the engagements between exhibitors and tire-kickers. Understandably, this is the premier event for the global satellite communications market, which is only expanding. While the budget concerns of any one country may slow down the rate of this growth, the overall market is robust and continues to expand.  As a result, the appropriate microwave component companies participating in this yearly event are mostly able to justify attending.

This is the kind of event that draws a broader audience and exhibitor base from big system platform manufacturers such as Boeing and Hughes, to sub-primes such as Harris, L-3 and Cobham to individual component manufacturers (see below). While the component manufacturer may share the exhibition space with its client companies, the personnel they need to talk to (i.e. engineers) may not necessarily be manning those booths. Still, it is impressive to see how microwave hardware is integrated into SATCOM systems and making a trip to this annual event a worthwhile venture for techies as well as business folk.

 Most of the RF/Microwave products on display include passive waveguide components, timing sources, SSPAs and BUCs, Cables/connectors, and test solutions. Vendors in who offer products in this “space”, are able to tout reliability, space qualification (although not necessarily if the customer is willing to foot the bill for testing), lightweight and compact, performance and having a solution for the band of interest.

 Ever-changing demand, new applications and degrees of profitability will determine future business opportunities, however the international interest in satellite communication and navigation bode well for the continued growth of this industry. While the path to becoming a microwave hardware vendor of space qualified components may be long and challenging, the outlook for the extended SATCOM market is favorable for those who boldly look toward the future.
