Close, but not quite: S/A is an ADJUSTABLE variable, not on/off. it can reduce accuracy to 10 meters or 100 meters or whatever. It's a DoD term, not NWO term. The "this is where you really are" percision location (forgot the designation off hand) is ENCRYPTED (yes, there is crypto revelance here...) in the data stream from the satellites. The difference S/A makes is on the order of magnitude, therefore not "useless." It should be pointed out that different regions of the earth can have different degrees of accuracy based on the S/A system. I doubt S/A will ever be turned off, but this is my opinion. I know Jim's opinion. Discussion of this point is pointless. DGPS transmission are made from a multiple single points, which (to the best of my knowledge) are not networked. glenn
Does anyone else get a little upset at the thought of one Government agency (DoD) spending money to install the GPS system, then making it less accurate than it should be, and then a second Government agency (US Coast Guard) spending money to improve the system by installing DGPS stations. Plus, in order to get the real accuracy of GPS right now I have to spend more money on a much more expensive DGPS unit. Pisses me right the F### off.
