Scope

ESA Ground Segment Technologies are represented in the ESA Directorate of Operations and Infrastructure (D/OPS), located at ESOC in Darmstadt/Germany.

This presentation gives a brief summary of the technology trends and strategy, and its translation into the TRP Plan 2011-2013 without anticipating the decisions to come (TRP candidate subjects in blue)

A roadmap involving technology and infrastructure activities is being consolidated in ESOC to cover the complete product development lifecycle.
