By now most of those who care probably know - but just in case.
Effective Monday, May 1, 2000, the scrambling effect that the U.S.
Government previously introduced into the satellites has been
removed. This means there should be a greatly improved accuracy
possible with all GPS units and the purchase of a new GPS receiver
will NOT be required.
The quoted improvement in accuracy is that before you could
guarantee yourself to be somewhere on a football field and now you
will be able to guarantee yourself to be somewhere on a tennis
court.
The numbers I have been able to locate show a football field to be
approximately 50 x 100 meters and a tennis court to be approximately
12 x 25 meters. (Very, very roughly 160 x 360 feet and 36 x 80 feet
respectively.)
If true this should turn the standard GPS from a relatively useless
device for our purposes into a very useful device.
If anyone has more accurate figures OR some real life accuracy
checks it would be useful for myself and others if you would share
with us.
