I was wondering how accurate and reliable is the property speed of a single sample of GeolocationCoordinates API.
I want to take few samples of the current speed of an object (with GPS) and I am not sure if I should calculate the velocity myself (by the distance traveled between two time samples using altitude, longitude and altitude), or just use the property speed of a simple GeolocationCoordinates sample.
How does the speed property is being measured? Which approach should I take?
from How accurate and reliable is GeolocationCoordinates.speed API?
