GPS Enterprise Integrator
Abstract
The Global Positioning System (GPS) Enterprise Integrator (EI) is responsible for integrating, synchronizing, testing and verifying the three ACAT I Defense Acquisition Programs that constitute the GPS Enterprise. Moreover, GPS EI is responsible for delivering reliable Positioning, Navigation, and Timing (PNT) signal capability to military operators, the civil user community, and international partners. Similarly, the Government Joint Program Office owns and approves the technical baseline and is responsible for the successful fielding of all the GPS Segments (space, control, and user). In order to successfully execute its responsibilities, the Government relies on GPS EI's specific expertise to create an enterprise architecture, integrate segment products, and verify the enterprise requirements are adequately met. The GPS EI is also responsible for developing and managing the Enterprise technical baseline, which reflects multiple stakeholders' requirements. Such stakeholders include the Department of Defense (DoD), foreign governments, industry, and the general public (through four Interface specifications). Furthermore, GPS EI ensures GPS capabilities meet the warfighter's, civil agencies', commercial entities', international treaties', and over four billion global GPS users' needs. The GPS EI also manages the process through which the JROC validated requirements are matured and flowed down to the system segments, while remaining consistent with various interfaces. This enables the GPS system to meet Title 10 of the U.S. Code, Section 2281, mandated GPS capabilities and various other obligations to the international community that provide inter-operable PNT signals. GPS EI is also responsible for all aspects of schedule and technical alignment across the segments. Additionally, GPS EI is responsible for creating and managing plans that provide early exercise of the products under development, compatibility analysis, and inter-segment testing, which result in risk reduction. The inter-segment tests are required to prove GPS Next Generation Operational Control System's (OCX) interoperability with GPS III satellites, and modernized user equipment. More importantly, it ensures backwards compatibility with GPS Block II satellites and legacy user equipment. GPS EI activity supports the Government Joint Program Office's GPS spectrum protection at international forums such as the International Telecommunications Union. Such support consists of advocating on behalf of the United States Government when negotiating with foreign partners. In addition, GPS EI provides technical expertise to maintain relationships with other U.S. government agencies that include the Federal Aviation Administration (FAA), National Geospatial-Intelligence Agency (NGA), National Aeronautics and Space Administration (NASA), Departments of State (DOS), Transportation, Homeland Security, and Commerce. Spectrum expertise also ensures GPS priority over eight essential spectrum signals required for civil air navigation such as the safety of life signal and L5. Spectrum Protection prevents encroachment from commercial or foreign entities, which results in the preservation of warfighter's reliable signal. As a result, military operations and the integrity of the global economic infrastructure are protected. GPS EI is also the GPS enterprise expert on Cybersecurity, System Safety, and System Security, which ultimately ensures a protected GPS Signal for both the military and civil users. GPS EI is accountable for the development, execution, and analysis of OCX, cybersecurity and associated test cases necessary to deliver a secure operational system. GPS EI supports the Government development and implementation of various Systems Engineering documents, defines the methods of verification, conducts the analyses or tests, and assists the government in leading Integrated System Tests. In addition, GPS EI validates the system performance in various mission threat scenarios during its development. GPS EI provides in-depth technical expertise to enhance government control, oversight and program accountability.
