sorry if i'm being missing the point and being pedantic, but i'm sure
latitude measures angle north/south of the equator.

longitude measures the angle east/west of the greenwich meridian

are you at a point where the two have similar values, and getting them
the wrong way round?

alternatively, how precise is the lat/lon reading? tangogps provides
an hdop value - realistically, this should be as low as possible.
maybe you can't get a good fix, because of trees/buildings/old kernel
with microsd interference?
