Next Generation Operational Control System (OCX)
Abstract:
The Global Positioning System GPS is a space-based positioning, navigation, and timing distribution system, which operates through weather and electromagnetic environments jamming, spoofing, etc.. GPS supports both civil and military users in air, space, sea, and land operations. GPS is a satellite-based radio navigation system that serves military and civil users worldwide. GPS users process satellite signals to determine accurate position, velocity, and time. GPS must comply with section 2281 of title 10, United States Code USC, which requires that the Secretary of Defense ensures the continued sustainment and operation of GPS for military and civilian purposes and section 50112 of title 51, USC, which requires that GPS complies with certain standards and facilitates international cooperation.
