Using Cell phone GPS System as Speedometer. Dangerous?

[Sinbad]

An undercalibrated speedo? A bit harsh, given that quite a number of factors play into the accuracy of a speedometer...

Nope. the SANS standard is as quoted. If it doesn't meet standards, it's not approved.

The data doesnt bother me. I have tons of it. Just sometimes the lack of access to data bothers me.

Move from CellC

Drive & walk is also free on my S2. And works well offline.

Ok, so this is on the basis of a vehicle coming as-is from the factory... Fair enough.

If speed is all you're after on Android, use something like GPS Test. For me it was worth paying for the (ad free) Plus version, besides GPS sat info, gives speed, accurate time, direction (compass), height etc.

I have been pushing the speed to the limits (like driving at 130km/hr as per speed indicated by Nokia Drive on my Lumia in the face of a speed camera - I saw two) so I will give you feed back within this month to let you know if I have fines or not as a result.

For me, the fines would be a litmus test of how accurate the Lumia's GPS is (assuming that JMPD's trapping devices are accurate).

Your phone's GPS is definitely more accurate, probably even more than the JMPD's cameras. Anyone who is serious about measuring speed data uses a GPS based system. IMo if you are driving 130km according to the phone, then you are too fast.

Can you elaborate on the anyone part. Do you mean companies or simply individuals.

Are GPS based speed measuring systems the trusted/prefered speed measurement system, professionally?
