Global Positioning System III - Operational Control Segment
Abstract
The Global Positioning System (GPS) is a space based Positioning, Navigation and Timing (PNT) 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. This Program Element (PE) funds the Research & Development for the next generation GPS control segment (OCX) and the GPS Enterprise Integrator. This includes the advanced concept development, systems analysis, modernized control segment development, training simulators, Integrated Logistics Support (ILS) products, and developmental test resources, and systems engineering required to meet the government’s obligations to the international, military and civil communities. OCX acquisition was established to 1) fly legacy and GPS III satellites, 2) incorporate situational awareness to support Navwar and signal monitoring, and 3) enable mission capability upgrades to support warfighter Effects-Based Approach to Operations (EBAO). GPS Enterprise Integrator is responsible for architecture and system definition (the analysis and definition, management, maintenance, and evolution of the GPS Enterprise requirements and interface technical documents) as well as for the planning, execution, and fielding of the Enterprise. OCX funds will support engineering studies and analyses, architectural engineering studies, trade studies, technology needs forecasting, systems engineering, system development, test and evaluation efforts and mission operations in support of upgrades and product improvements for military and civil applications necessary to support efforts to protect U.S. military and allies' use of GPS. Additionally, funds will ensure a disciplined Capability Insertion Program (CIP) plan to meet Joint Requirements Oversight Council (JROC) approved required capabilities. Funds will support science and technology, technology development and systems development efforts. GPS supports both civil and military users in air, space, sea and land operations. The GPS Enterprise consists of Space, Ground Control, and User Equipment Segments. The government is responsible for the integration of the three GPS Segments such that they provide worldwide GPS capability to support the warfighter and over a billion national security, civil, allied, and commercial GPS users. The GPS Enterprise Integrator project includes the efforts associated with the Government’s prime contract tasks necessary to accomplish this critical integrating function. The Enterprise Integrator maintains the GPS architecture and system definition, ensures compatibility of Generation II and III systems, and develops/manages plans for execution and fielding of the GPS Enterprise. Further, the Integrator provides analyses to support Government-directed enterprise level trades among the GPS segments leading to definition, management, maintenance, and evolution of the GPS Enterprise requirements and interface technical documents. In addition, the GPS Enterprise Integrator project funds support for the delivery of all GPS Enterprise capabilities. Examples for Generation II include electronic protection and additional civil signals; for Generation III, additional anti-jamming protection. To accomplish this, GPS Enterprise Integrator delivers architecture and trade studies between space, control, and user segments, with recommendations presented to the Government through a formal change board process. GPS Enterprise Integrator’s analyses guide government decisions to ensure efficient and effective synchronization and execution across all Generation II and III GPS programs as well as studies concerning potential future GPS alternatives. For Enterprise-wide integration to be successful, the Integrator: works with the GPS Segment ACAT-1D prime contractor teams to develop plans for early risk reduction System Integration (SI) Demos to ensure system interfaces and functionality meet user and system requirements; establishes Giver/Receiver Lists that ensure all equipment and documentation is ready when needed; conducts formal test and verification, including Requirement Verification Plans; and System Test Plans and Procedures. GPS Enterprise Integrator performs all these efforts across all GPS programs in all acquisition phases. The government owns the Enterprise system requirements and integration, and with support from the Enterprise Integrator team eliminates the need to fund a development prime contractor to perform these functions. This enhances government oversight and accountability.
