(after a quiet period from me)
Global Positioning by satelite, accurate to a couple of meters - great. Simple, cheap, perfect for a duffer like me. BUT
, notice on chart tells me...Satelite-Derived Positions are normally referred to WGS Datum. such positions should be moved 0.02 minutes Northward and 0.09 minutes Eastwards to agree with this chart.
Why are they trying to confuse me? And just who are THEY anyway?
Does this mean that if I am stuck out at sea and am calling for help that I have to read my gps (which SANTA has promised me for Christmas) and then SUBTRACT the above to give my correct position?
