You better read up on how GPS's work.
The GPS will show where YOU are when detecting the AP's, not where the AP's are.

The only way to locate the AP's with use of a GPS, is by taking multiple readings from different locations, and then do triangulation.
And even in that case the triangulated location will be unprecise due to such things as multipath reflections, skewed amount of readings from different positions, etc, etc..
