摘要

The U.S. federal budget has entered a period of painful contraction that will result in the termination of numerous technology programs. Casualties in the space community already include the Transformational Communications Satellite system, the Constellation civil spaceflight program, and a next-generation weather satellite that would have far surpassed the performance of existing systems. The loss of each of these programs was a setback to America's role as a global leader in space, foreclosing economic and military advances that one day soon might be accomplished by other powers. However, there is far worse damage to come if our political system cannot distinguish between investments that are merely desirable and those that are truly vital. A case in point is the next-generation refinement of the Global Positioning System, popularly known as GPS 3. GPS has become part of America's critical infrastructure, a utility that is essential to everything from cellular communications to smart bombs to air traffic control. Like the Internet, it is so ubiquitous in everyday commerce and culture that we seldom reflect on what life would be like without it.
