Quick question. Is the groundcourse angle from sirf moduals tangent to the current path or is it the angle between the current location and the last location reported 1 second earlier?I assume of it were tangent - and more accurate- it would be doing more internal calculations than I think it does, so I'm skeptical. This is a little hard to test so if someone has the answer it would save me a ton of time.Thanks.Jason

Hi Jason,
Not sure, but they probably are just giving you the arctan of their velocity vectors, since that it needed for the calc anyway. Take a stream of data and compare the two (atan2 of velocity and their reported heading) in a walking test down the street...
