Interface PositionService

public interface PositionService

This interface provides methods getting a geographic position. The OSGI Position class represents a geographic location, based on the WGS84 System (World Geodetic System 1984).

Position(Measurement lat, Measurement lon, Measurement alt, Measurement speed, Measurement track)

The interface also return a NmeaPosition, subclass of Position

NmeaPosition, Position, Measurement

Method Summary

String	getLastSentence() Returns the last sentence received from the gps.
String	getNmeaDate() Returns the current NMEA date from ZDA sentence
NmeaPosition	getNmeaPosition() Returns the current NMEA geographic position.
String	getNmeaTime() Returns the current NMEA time from GGA or ZDA sentence
org.osgi.util.position.Position	getPosition() 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.
boolean	isLocked() Returns true if a valid geographic position has been received.

Method Detail

getPosition

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

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.

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

getSpeedKmh() : returns the ground speed of this position in km/h.

getSpeedMph() : returns the ground speed of this position in mph.

getTrack() : Returns the track of this position in degrees as a compass heading.
