(U) A. Mission Description and Budget Item Justification

This program element funds Research and Development for the NAVSTAR Global Positioning System (GPS) space and control segments of the overall GPS program. This includes: satellite development (except Block IIF), procurement, and deployment; training simulators; Mission Operation Support Center (MOSC); and operation of the ground control segment, including sustaining engineering, upgrades to the space and ground segments, and R&D efforts to support deployment of the entire GPS system. As a post-Milestone 3 program, we are classified as Budget Activity 7, Operational Systems Development.

(U) Acquisition Strategy: The acquisition strategy is to competitively procure Block IIR satellites and associated supporting services.
