Hi,
I use the GPS library for my app.
My app is for car tablets to check speed and period service.
There is a problem.
I try show car speed on the label, but that is wrong value why?
My car is moving 40km per hour but my the app show 10 km per hour

The speed of the car cannot be the same as the speed on the GPS satellite..

How do you know it is not the right value?

Car speedometers usually err on side of caution ie read higher than actual speed.

So if your speedometer is showing 40 km/h then it is entirely plausible that your actual speed is 36 km/h.

Because max speed is 10 km while I'm running a car with 100km or 50km
There is an app in the tablet monitor that show right speed
I guess tablet GPS has a problem
