GPS vs. Compass Module for direction
Hello,
If someone could help me with this one that would be great.· Does anyone know how any of the GPS modules compare with the compass module that I have been using as far as accuracy goes?· It is http://www.parallax.com/Store/Sensors/CompassGPS/tabid/173/ProductID/98/List/1/Default.aspx?SortField=ProductName,ProductName
At first glance, the compass is better for indoors but it's only as good as your calibration.· But, in an outdoor setting, I would assume the GPS is more accurate for direction.· Can anyone verify this?
Thanks ahead!

There is one other question I still have about the GPS module. Is there any recommendations for mounting? I had assumed that that antenna should be up but wasn't sure if there was a "front" of the sensor that should be facing forward (the normal direction of travel) which I would be concerned about using a compass. Since there isn't a compass module I suppose mounting isn't a issue.
