How accurate is it, then?
Scatter plot: http://www.gral-gju.org/examples.php
“95% of GPS position measurements willlie within 5 metres of the true position”
provided … • GPS receiver operating OK• Installation OK• Has acquired satellites• Aerial can see sky• No blockages• No reflections• No interference
