Hi! When I was on holiday, I ended up to write a gps app, and I wondered how to measure speed exactly. My first attempt was, that I take the gps coordinates every second, and I calculate how many meters I walked/biked. Then I discovered, that fso reports speed too (although in knot units),

I think the chip accuracy has nothing to do with it. As I can see from the picture, right now you just have reported speed at time points connected with straight lines. This is why it's so hairy - because it's a raw speed at 1 second rate. What you want to do is to use some kind of filter, for
