Greenwich: Greenwich Park: The Millennium Sundial
Greenwich: Greenwich Park: The Millennium Sundial
This is on the north side of TQ3877 : Greenwich: Greenwich Park: The Boating Lake

The sundial is positioned such that the north-south line is intended to be on the Greenwich Prime Meridian. However this is astronomical longitude, and if one places a GPS receiver on the line it will be out by about 5.3 seconds of arc or about 102 metres westwards. This is because GPS uses geodetic longitude which equalizes the actual mass of the earth.
