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.

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.
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.
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.
