Variables
Returns a double representing the accuracy of the latitude and longitude properties, expressed in meters.
Returns a double representing the position's altitude in metres, relative to sea level. This value can be null if the implementation cannot provide the data.
read onlyaltitudeAccuracy:Float
Returns a double representing the accuracy of the altitude expressed in meters. This value can be null.
Returns a double representing the direction in which the device is traveling. This value, specified in degrees, indicates how far off from heading true north the device is. 0 degrees represents true north, and the direction is determined clockwise (which means that east is 90 degrees and west is 270 degrees). If speed is 0, heading is NaN. If the device is unable to provide heading information, this value is null.
