The GPS provides positioning, navigation, and timing (PNT) data to users worldwide. The U.S. Air Force (AF) is in the process of modernizing the system. But, it is uncertain whether the AF could acquire new satellites in time to maintain GPS service without interruption. This report assesses: (1) the status of AF efforts to deliver new GPS satellites, the avail. of the GPS constellation, and the potential impacts on users if the constellation avail. diminishes below its committed level of performance; (2) efforts to acquire the GPS ground control and user equipment necessary to leverage GPS satellite capabilities; (3) the GPS interagency requirements process; and (4) coord. of GPS efforts with the internat. PNT community. Illus. This is a print on demand report.
The Global Positioning System (GPS), which provides position, navigation, and timing data to users worldwide, has become essential to U.S. national security and a key tool in an expanding array of public service and commercial applications. The Air Force is in the process of modernizing GPS. In light of the importance of GPS, the modernization effort, and international efforts to develop new systems, the auditor undertook a broad review of GPS. Specifically, she assessed progress in: (1) acquiring GPS satellites; (2) acquiring the ground control and user equipment necessary to leverage GPS satellite capabilities; and (3) evaluated coordination among fed. agencies and other org. to ensure GPS missions can be accomplished.

The majority of large-scale acquisition programs in the DoD space portfolio have experienced problems during the past two decades that have driven up costs by billions of dollars, stretched schedules by years, and increased technical risks. To address the cost increases, DoD altered its acquisitions by reducing the number of satellites it intended to buy, reducing the capabilities of the satellites, or terminating major space systems acquisitions. Many space acquisitions are experiencing significant schedule delays resulting in potential capability gaps in areas such as missile warning, military commun., and weather monitoring. This testimony focuses on: the status of space acquisitions; factors of acquisition problems; and efforts to improve acquisitions. Illus.
The DoD has had long-standing difficulties developing and delivering space systems on time and within budget. Attempts to reform DoD space acquisitions in the past have sought to leverage commercial approaches or rely more on the commercial sector to meet DoD needs. This report examined the following questions: (1) What are the differences between commercial and national security space system missions, requirements, and technology development? (2) What acquisition practices adopted by commercial co¿s. could be used for national security space system acquisitions? (3) Which acquisition practices adopted by commercial co¿s. may not be readily adaptable for national security space system acquisitions? Charts and tables.
In May 2009, Congress passed the Weapon Systems Acquisition Reform Act of 2009 (Reform Act). The Reform Act contains a number of systems engineering and developmental testing requirements that are aimed at helping weapon programs establish a solid foundation from the start of development. This report examined: (1) DoD's progress in implementing the systems engineering and developmental testing requirements; (2) views on the alignment of the offices of the Directors of Systems Engineering and Developmental Test and Evaluation; and (3) challenges in strengthening systems engineering and developmental testing activities. Includes recommendations. Charts and tables.
Compares quality mgmt. practices used by the DoD & its contractors to those used by leading commercial co¿s. & made suggestions for improvement. The report: determined the impact of quality problems on selected weapon systems & prime contractor practices that contributed to the problems; identified commercial practices that can be used to improve DoD weapon systems; identified problems that DoD must overcome; & identified recent DoD initiatives that could improve quality. The author examined 11 DoD weapon systems with known quality problems & met with quality officials from DoD, defense prime contractors, & 5 leading commercial co¿s. that produce complex products &/or are recognized for quality products.
