Check that Location.SpeedValid is True. If it is then Location.Speed should give your speed in metres/second. Your reading of 10 m/s is 36 km/hr.
link: If there is an app on the same tablet that shows the right speed, then the problem is unlikely to be with the tablet. Is your B4A app always showing

link: 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 h

Locations that are (nearly) antipodal may produce meaningless results. DistanceTo (Dest As LocationF) As Float Returns the approximate distance in meters between this location and the given location. Distance is defined using the WGS84 ellipsoid. HasAccuracy As Boolean Returns true if this location

Check the GPS example As you can see, you can save it instead of assigning to lalLat and lblLon. Public Sub LocationChanged(Location1 As Location) lblLat.Text = "Lat = " & Location1.ConvertToMinutes(Location1.Latitude) lblLon.Text = "Lon = " & Location1.ConvertToMinutes(Location1.Longitude)

You can forget trying to calculate the speed using the accelerometer. The result will be much too unaccurate. Use the GPS you get the speed with Location.Speed. The unit is meters/second. To get km/h multiply by 3.6.

Ok, here is the new dialog text I would suggest: Location Authorization This app needs to obtain information about your location so that it can: 1) Use GPS satellite data to make sure all location and trip times are accurate in this app 2) Continuously monitor and record your vehicle's speed, dire

NO_ACTION - No further action will be taken on completion of mission. GO_HOME - The aircraft will go home and land. AUTO_LAND - The aircraft will land at the last waypoint. GO_FIRST_WAYPOINT - The aircraft will go to the first waypoint. CONTINUE_UNTIL_END - Mission will not end until StopMission is
