Available in PDF, EPUB and Kindle. Book excerpt: The Global Positioning System (GPS) is a U.S. military space system operated by the U.S. Air Force. The space segment of GPS consists of a constellation of 24 satellites that broadcast precise time signals. When the satellites are in view of a suitable GPS receiver, these signals aid position-location, navigation, and precision timing. GPS was developed by the U.S. Department of Defense and deployed over two decades at a cost of over $10 billion. The U.S. armed forces are increasingly reliant on its signals for a variety of purposes from navigation to munitions guidance. However, over the past 10 years, GPS has evolved far beyond its military origins. It is now a worldwide information resource supporting a wide range of civil, scientific, and commercial functions, from air traffic control to the Internet. GPS has also spawned a substantial commercial industry in the United States and abroad with rapidly growing markets for related products and services.

Book excerpt: This book explores the significant challenges in sustaining and upgrading The Global Positioning System (GPS). The GPS provides positioning, navigation, and timing data to users world-wide, and has become essential to U.S. national security and a key tool in an expanding array of public service and commercial applications at home and abroad. GPS is integrated into nearly every facet of U.S. military operations, and the number of civil users is increasing. Other countries are now developing their own independent global navigation satellite systems that could offer capabilities that are comparable, if not superior to GPS. The U.S. government, which plans to invest more than $5.8 billion from 2009 through 2013 in the GPS space and ground control segments currently under development, provides GPS service free of charge. The Department of Defense (DoD) develops and operates GPS, and an interdepartmental committee manages the U.S. space-based positioning, navigation and timing infrastructure, which includes GPS. This book looks at the global economic and national security importance of GPS, the ongoing GPS modernisation effort and the international efforts to develop new systems.

Available in PDF, EPUB and Kindle. Book excerpt: On April 9, 2004, the acting USD (AT&L) and the ASD (NII) jointly requested that the Defense Science Board undertake a Task Force on the future of the Global Positioning System (GPS). The request focused on the implications for GPS from a civil-commercial Galileo, the European Union's proposed Global Navigation Satellite System (GNSS). The Terms of Reference also requested assessment of several other aspects of GPS military and commercial competitiveness and of upgrade strategies and technical alternatives. The DSB empanelled a Task Force comprised of GPS experts with extensive public and private sector experience. Deliberations on relevant GPS topics were conducted primarily among the Task Force members with outside briefings limited to current activities affecting the program itself and other directly relevant topics. During the course of the year several outside events significantly modified the issues of uncertainty that had existed when the Task Force was formed. Those events included the signing of a cooperative agreement on GPS and Galileo between the United States and the European Union in June 2004, a major study on GPS commercial viability as approved by the Deputy Secretary of Defense in October 2004 and signature by the President of an updated national policy on GPS and related systems in December 2004. While each of these events moderated specific areas of uncertainty that had been complicating GPS planning, each is still a work in progress that will require monitoring as leadership moves to address the still substantive issues facing GPS operation and evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Since World War II the United States has yielded many of its policy decisions to the desires of the United States military. These policy decisions reach from nylon and aluminum restrictions for the war efforts of World War II through the tough military build-up policies of the 1980s amidst fiscal constraints. In the aftermath of the conflict in Vietnam, President Ronald Reagan was determined to regain America's influence in the world by rebuilding the military and strengthening the economy. In 1989, the Berlin Wall came crashing down as the prelude to the fall of the Soviet Union and the Iron Curtain of communism. Without the apparent threat of war with the Soviet Union, the United States began to focus more on maintaining an economic and political leadership role around the world. No longer did the United States military hold a firm grip on the rudder of national policy. Instead, a balance between the amount of military power required to remain relevant in the world and economic and political influence was sought. One of the tools provided by the military to the civilian community is the Global Positioning System (GPS). This system, originally designed for the United States military, was released for public use in a degraded form after the tragic downing of a Korean airliner by Soviet fighter aircraft after the airliner unknowingly strayed into Soviet airspace in 1983. The GPS system's full accuracy capability was not released to the public out of fear by the Department of Defense (DOD) that potential adversaries might use the system for inertial guidance of smart munitions against the U.S.
