Colloquium Synopsis

What is the New Space and how does it relate to the modern society that has increasingly become dependent on it? Our global communications networks, weather forecasting, natural resources exploration, disaster response and national security are all critically dependent on the traditional but somewhat stovepiped technologies and domains. The GEO satellites focused on communications and video distribution, the MEO satellites have led position and timing services, and the LEO satellites had been widely used for earth sensing. Governments initially played a critical role in triggering the space age and still have exclusivity over some domains. Over the past few decades, however, commercial industry has matured and now dominates the worldwide global communications and satellite networks.

Today, we are in a new era when two new multibillion dollar LEO constellations, namely OneWeb and Starlink, that are in the orbit and rapidly connecting customers worldwide. A strong third LEO constellation with Amazon Kuiper is emerging and has started launching satellites. The incumbent GEO providers are going through mergers and multi-orbit alliances, application domains are merging, software-defined satellite payloads are commonly used, and some of the largest global technology companies are becoming major players in the space industry. Governments are leveraging commercial investments while designing protected systems and LEO constellations with exquisite capabilities.

The AIAA CMSTC (Communications Systems Technical Committee), under the auspices of the International Communication Satellite Systems Conference (ICSSC), has a long history of organizing successful colloquia that address emerging technologies including 5G, Megaconstellations, Multi-Orbit Systems of interest to the satellite communications community. Last year’s 40th ICSSC Colloquium on Direct Satellite to Cellular Mobile Services, was held in Bradford UK, kept with a proven forum of interactive workshop combined with leading industry presentation, and was attended by our largest audience to date with experts across industry, academia, and government.

This year’s Colloquium is planned to be held in Seattle on Tuesday 24th September 2024, a pre-event to the joint 29th Ka and 41st ICSSC Conference.
This year’s 2024 Colloquium topic is – Converging Orbits: Technical and Market Forces Shaping the New Space. The topic is to analyze the past, present and future of Space through the lens of new space dynamics. It will address the space industry disruptions fueled by vertically integrated tech companies building LEO megaconstellations, software-driven multi-purpose architectures, and increasing collaboration and competition across the launchers, satellite builders, operators, and governments.

This year’s Colloquium forum will be a full day long program in a workshop type setting, and with our interest of our target international satellite communications systems audience, we have a lined up a comprehensive technical, business, and regulatory panel of experts, addressing topics that include::

  • State of the Direct-to-Cell industry – technology and market
  • Use cases and business models (commercial, government, and hybrid)
  • Inter-satellite link, bent pipe, and processing payload trade-offs
  • Software-driven intra- and inter-orbit orchestration across orbits and technologies
  • Longer term technical implications – GEO, 5G, IoT, PNT, D2D – Unification with 3GPP NTN
  • Competition and collaboration across industry and governments
  • Regulatory: spectrum and orbital safety; spectrum sharing, industry government collaboration

Colloquium registrants will be given access to the presentation slides for their personal use,
