Working Group D

Cloud Computing and Big Data Technologies for Ground Systems


Wednesday- February 28, 2024
1:00 PM – 5:00 PM PT


This is the fourteenth year of this working group. The main objective of the working group is to continue discussion on the adoption of cloud computing and Big Data in satellite ground systems. The Cloud Reference Model and Roadmap produced by Aerospace will be used to frame the discussion. The working group will focus on:

  • State of the art in cloud computing and ground systems technologies;
  • Cloud reference models and roadmaps;
  • Cloud-based ground systems;
  • Cloud and Big Data technologies;
  • Cloud security, standards, and compliance;
  • Acquisition strategies for cloud-based systems;
  • Cloud computing economics; and
  • Cloud performance management.

This working group will consist of two parts. Part 1 will include presentations, case studies, and demonstrations related to cloud computing and Big Data for ground systems. Part 2 will be a town hall meeting on cloud computing and Big Data for ground systems. This will include a moderated discussion on the focus issues mentioned above, with expert opinions from panelists.

Presenters, panelists, and participants will include ground systems providers, integrators, and operators, cloud solutions providers, and others interested in ground systems and cloud computing.
