Briefing

What Hype is tracking

  • Completion of the preliminary design review formally shifts Epoch from concept to detailed design, a required gate before hardware procurement and integration.

  • This progress comes amid the GAO's finding that the SDA tracking layer faces risks to technology readiness, cost and schedule, giving broader programme risk context (see source:460e5df4-6940-4729-b736-09ae9995fef2).

  • Industrial momentum is visible: Sierra Space recently delivered the first nine satellite structures for an 18‑satellite tracking contract three months early, signalling active supplier timelines that will influence Epoch integration and delivery (see source:131d69a6-65f0-4c75-866d-3a7c89df8051).
