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.
DoD invests heavily in space assets to provide the warfighter with intelligence, navigation, and other info. critical to conducting military operations. Despite a substantial investment, senior military commanders have reported shortfalls in tactical space capabilities in each recent major conflict over the past decade. To provide short-term tactical capabilities as well as identify and implement long-term solutions to developing low cost satellites, DoD initiated operationally responsive space (ORS). Following a 2006 review of ORS, the Congress directed DoD to submit a report that sets forth a plan for providing quick acquisition of low cost space capabilities. This report focuses on the status of DoD¿s progress in responding to the Congress. Illustrations.
This is a print on demand edition of a hard to find publication. The DoD provides medical care to 9.6 million active duty service members, their families, and others. DoD's Military Health System has wanted to acquire and deploy an electronic health record system for some time. The latest version of this initiative -- the Armed Forces Health Longitudinal Technol. Application (AHLTA) -- was expected to provide real-time access to individual and military population health info. and facilitate clinical support. However, the system's early performance was problematic, and DoD has said that it intended to acquire a new electronic health record system. This report: (1) determines the status of AHLTA; (2) determines DoD's plans for acquiring its new system; and (3) evaluates DoD's acquisition management of the initiative. Illus.
The majority of large-scale acquisition programs in the DoD space portfolio have experienced problems during the past two decades that have driven up cost and schedules and increased technical risks. The cost resulting from acquisition problems has resulted in cancellations of programs that were expected to require investments of tens of billions of dollars. Many programs are experiencing significant schedule delays resulting in potential capability gaps in areas such as positioning, navigation, and timing; missile warning; and weather monitoring. This testimony focuses on: (1) the condition of space acquisitions; (2) causal factors; and (3) recommend. for better positioning programs and industry for success. Charts and tables.
