WASHINGTON - Global-positioning devices used to steer cars, fly planes =
or find skiers and hikers will be given pinpoint accuracy previously =
available only to the military under an order President Clinton signed =
yesterday.=20

Until now, civilians using a U.S.-built network of satellites for =
navigation got a less accurate reading than the military out of fear =
that potential enemies could use the system to target missiles.=20


Under the order, which took effect at 5 p.m. PDT yesterday, the U.S. =
military no longer is scrambling the Global Positioning System (GPS) =
satellite signals used by civilians. However, it still can block the =
signal over any given region.=20

The decision, based on four years of deliberations, is likely to be a =
boon to the GPS industry, which already is expected to double in the =
next three years, from $8 billion to more than $16 billion.=20

The possibilities for increased commercial use are wide: air, road, rail =
and marine navigation, precision agriculture and mining, oil =
exploration, telecommunications, electronic-data transfer, recreation =
and emergency response.=20

The change will make satellite-navigation devices that people already =
own 10 times more accurate, said White House science adviser Neal Lane, =
and will not require the purchase of new machines.=20

The difference will mean that satellite navigation can be used to track =
a missing person to an area about the size of a tennis court. Until now, =
the area of intense search would have been more like a football field.=20

That level of imprecision was problematic in emergencies and in efforts =
to pinpoint such things as a stranded motorist's exact location. With =
the less accurate system, a reading for the motorist might include both =
sides of a busy highway or even several different roads.=20

The GPS system is a product of super-reliable atomic clocks that emerged =
from Nobel-Prize-winning physics. It can calculate position, velocity =
and time anywhere on the globe, any time of the day or night, in any =
kind of weather.=20
