getPosition

public org.osgi.util.position.Position getPosition()

Description copied from interface: PositionService

Returns the current geographic position.
The org.osgi.util.measurement.Measurement class is used to represent the values that make up a position :

getLongitude() : returns the longitude of this position in radians.

getLatitude() : returns the latitude of this position in radians.

getSpeed() : returns the ground speed of this position in meters per second.

getTrack() : Returns the track of this position in radians as a compass heading. The track is the extrapolation of previous previously measured positions to a future position.

Specified by:
