[edit] what are lines of latitude called?

Anyone ever think of including the term for a line of latitude here? —Preceding unsigned comment added by 69.159.219.48 (talk) 15:28, 20 September 2007 (UTC)

[edit] What does your GPS navigator say?

During my visit to Greenwich on the 3rd of May 2008 I took my GPS navigator (MIO 268, SW 3.2) and hoped to see the coordinate being exactly zero for longitude. I was surprised to see around 0.00147 degrees West, which I roughly calculated into approximately 150m (!) offset. The navigator had a good satellite reception and indicated a 1.6m accuracy. Also the altitude had quite an offset compared to the plaque on the observatory, but I did not make a note of that unfortunately.

How is it possible that the navigator has this enourmous offset and how is it possible that it works fine on the road, on which I believe it is closer to the 1.6m offset than the 150m offset. Does anyone have the same or other experiences? (Marc van Beek, The Netherlands) —Preceding unsigned comment added by 193.173.39.45 (talk) 09:42, 5 May 2008 (UTC)
