A known way point is found and a correcting signal is broadcast to the mobile GPS unit to correct the error. If memeory serves the 1st generation system is good for +/- four inches. There was an article in the Deere publication "Furrow" this year that explained GPS rather well. Makes it tough to do surveys as maps often show a straight road while you are standing on the curve caused by a surveyors error 100-200+ years ago. The random error was cut from 100ft to I think 30 ft or so?
