GPS Enterprise Integrator
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 provides a worldwide capability that supports over a million warfighters and over a billion national security, civil, allied, and commercial GPS users. The GPS Enterprise consists of four segments: Space, Ground Control, Nuclear Detonation Detection System (NDS) and User Equipment Segments. Each segment has prime contracts to provide specific segment products (eg. spacecraft, master control system, receivers & antennas). The government, not a development contractor, is responsible for the integration of the GPS Segments and relies upon GPS Enterprise Integrator contracts to supply specific expertise and sufficient resources to successfully allocate the segment requirements, integrate the segment products, and verify that system requirements are met. The GPS Enterprise Integration project includes the efforts of the FFRDC and SE&I contract tasks necessary to accomplish this critical integrating function. The Enterprise Integration maintains the GPS current architecture and system definition, controls and validates interfaces, ensures compatibility of previous, current, and future GPS segment products (Generation II and III systems), and develops/manages plans for execution and fielding of the GPS Enterprise. Further, the Integrator provides modeling, simulation and technical analyses of impacts for 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 to build and ensure the integrity of the enterprise technical baseline. In addition, the GPS Enterprise Integration project funds the technical evolution, risk reduction, enterprise-level testing and 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, the GPS Enterprise Integrator delivers Test and Verification capabilities, Requirements and Interface Management, and Systems Integration support across the Space, Control and User Segments. In this capacity, the Enterprise Integrator is responsible for managing this cross-program work to provide these and other capabilities. GPS Enterprise Integrator's analyses guide government decisions to ensure efficient and effective synchronization and execution across all Generation II and III GPS programs. For Enterprise-wide integration to be successful, the Integrator: works with the GPS and NDS prime contractor teams to develop plans for early risk reduction System Integration Demonstrations to ensure system interfaces and functionality meet user and system requirements; ensures all equipment and documentation is ready when needed; integrates and analyzes enterprise schedules, 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 highly leverages the Enterprise Integrator team to eliminate the need to fund a development prime contractor to perform these functions. This enhances the government control, oversight and program accountability. This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to support operational systems.
