From the Associated Press: WASHINGTON (Mar 29, 1996 12:21 p.m. EST) -- The Clinton administration announced today it will loosen military security restrictions and allow greater commercial use of a global navigation system. In a move that Vice President Al Gore said could turn a $1 billion industry into an $8 billion industry in four years and create 100,000 jobs -- mostly in California -- the administration said it can protect military security while expanding access to the system. "We are harnessing power in the sky to chart a prosperous new course on the ground," Gore said at a White House news conference. Under a newly approved White House policy, the Pentagon will end in four to 10 years its practice of degrading the quality of the Global Positioning System signal available for commercial use. That practice had been designed to ensure a technological edge for U.S. military forces. But technologies being developed will be able to secure the military GPS system. As a result, a far more accurate GPS system will be available for cars, airplanes, trains, trucks, ambulances, oil tankers, even hikers. Using small, portable receivers to pick up satellite signals, GPS users can pinpoint their locations anywhere in the world, even at sea, under any weather conditions. "Before long it's going to be very difficult to get lost," said Charles R. Trimble, president of Trimble Navigation Ltd. of Sunnyvale, Calif. Trimble's company is one of several high-tech firms in California that stands to benefit from the new policy. Trimble, whose company built the equipment used last year to recover downed fighter pilot Scott O'Grady in Bosnia, said the White House move would open up overseas markets to manufacturers of GPS equipment. And Transportation Secretary Federico Pena said that while the policy change won't take place immediately, the announcement gives the private sector a clear statement of where administration policy is going and clears the way for development of new commercial GPS systems. An official at Rockwell International Corp., which manufactures GPS receivers, said Thursday his company could do more business with airlines interested in using it as a landing aid and in planning flight routes. It also is used in car navigation. The news conference was the latest in a series of White House press events designed to highlight the degree to which the administration is on the cutting edge of high-tech commercial communications developments. It included a slide show, film clips of GPS users, and an outdoor demonstration of a car fitted with GPS equipment. Gore said that under the new policy, the government will collect no fees from commercial users of the constellation of 24 satellites that produce the signals. The Pentagon has invested $5 billion in the satellite network and expects to spend another $5 billion by the end of the decade. Commercial use has been limited by the Defense Department, which developed the system and operates it, out of national security concerns. The U.S. military views the GPS technology as an important battlefield advantage. In the 1991 Persian Gulf War, for example, GPS receivers mounted on U.S. tanks and other combat vehicles enabled the Army to navigate the Iraqi desert with precision. Among other things, the military uses GPS to provide more precise guidance to missiles and shells.
