WA, Australia | so if there is little difference between the WGS84 and ITRF05 projection and the NMEA is raw un-projected co-ordinate's. Where does the difference come from when in a controlled traffic situation the JD and Trimble systems start on the same lines one end of the paddock but separate at the other.
I was told that one company use magnetic north and the other true but couldn't see how this would affect GPS co-ord's
Thinking out load is it created when the lines are transferred through a desktop program and then exported? | |

Map projections?
