speedAccuracy property

double get speedAccuracy

Accuracy estimate for the speed measurement in meters per second.

Indicates the precision of the speed data. Typical accuracy for consumer GPS devices is approximately 2 m/s under good conditions with steady speed and high position accuracy. Valid speed accuracy values are always positive.

Not available on web: the browser Geolocation API does not report a speed accuracy, so this always returns -1 there.

Returns

• double: Speed accuracy in m/s (positive, or -1 if unavailable)

Implementation
