WASHINGTON — The conversations that dominated the last two World Satellite Business Week conferences centered mainly on increasingly capable high-throughput satellites in geostationary orbit and on constellations of numerous, smaller satellites in lower orbits.

The core branches of the satellite ecosystem — manufacturers, launchers, and ground equipment providers — had hoped that by 2018 those satellite-operator musings would have leafed out by now.

Some of them have, but too many have not. While most if not all satellite operators see internet-beaming high-throughput satellites as part of their future, satellite technology is advancing so rapidly that many fear ordering the wrong satellite today will leave them with a spacecraft that’s obsolete before it’s earned back its investment.

Satellite operator paralysis has gone on long enough that the rest of the ecosystem has sought comfort in knowing that operators at a minimum need replacements for their existing satellites before they fail, and therefore can’t hold off forever on contracts to build, orbit and utilize new spacecraft.

The first three days of World Satellite Business Week 2018, taking place Sept. 10-14 in Paris, will focus on satellite communications, while the last two days bring attention to the also dynamic market of space-based Earth observation.

Big questions that will hopefully find answers at this year’s conference include: how many satellite manufacturers and launch providers can the market support? Do markets like the Internet of Things and inflight connectivity hold as much promise as satellite operators hope? And, of course, what to satellite operators actually want?
