GPS

Post 1

Just thought I'd mention that GPS is now accurate to about +/- 10 metres.

This is only since 01 May 2000, when the US DoD switched off SA (the 'noise' that is added to the civilian version of the signal).

So the civilian GPS is now identical in accuracy to the military one.

Unless you happen to be using it in an area which is at war with the USA!
