摘要

U.S. GPS managers attending the Munich Satellite Navigation Summit had advice for their Russian, European and Chinese counterparts, who are all planning GPS-sim-ilar global constellations: Be patient. "The first GPS satellite was launched 30 years ago, in February 1978," said Richard W. McKinney, director of the European Space Liaison at the Office of the Under Secretary of the U.S. Air Force, which runs the GPS system.
