Any software to measure 0-60mph time?

Is it possible or is GPS too inaccurate for this application?

The speed is very accurate (0.1 MPH in good conditions) but there are a number of problems.

To do it with a consumer grade GPS is difficult, the obvious problem is that most units only output position information every second. Mathmatically, you could have an educated guess at where the 60 point was (ie, if you were doign 55 MPH one second and 65 the next then it probably was .5 seconds ago). I don't know what sort of accuracy you would get though.

The other more serious problem is that it's not always easy to accurately detect when the vehicle starts moving using a GPS unit. If you had some other hardware (ie accelerometers) then you might be able to cook something up to accurately detect your start time.

Also, the position/speed output by your GPS may lag behind reality by a second or two.

So, it's not as trivial as plugging a laptop into a GPS unit and logging the data for processing later. Confused

There was a commercial company that claimed to have a GPS based unit that could measure 0-60 times but I can't recall the name of them. I have also heard of "10Hz" GPS which output updates at 10 times per second which could do the trick, but I don't know who makes them or cost/availability.
