    BROYE-LES-PESMES, France - A French space-surveillance radar has detected 20-30 satellites in low Earth orbit that do not figure in the U.S. Defense Department's published catalogue, a discovery that French officials say they will use to pressure U.S. authorities to stop publishing the whereabouts of French reconnaissance and military communications satellites.
    After 16 months of operations of their Graves radar system, which can locate satellites in orbits up to 1,000 kilometers in altitude and even higher in certain cases, the French Defense Ministry says it has gathered just about enough information to negotiate an agreement with the United States.
