  • 方法详细资料

    • getCorrectedCourse

      double getCorrectedCourse()
      Get the corrected course over ground. Correction is done by subtracting or adding the magnetic variation from true course (easterly variation subtracted and westerly added).
      返回:
      Corrected true course
      抛出:
      DataNotAvailableException - If course or variation data is not available.
      ParseException - If course or variation field contains unexpected or illegal value.
      另请参阅:

    • getCourse

      double getCourse()
      Get true course over ground (COG).
      返回:
      True course in degrees
      抛出:
      DataNotAvailableException - If the data is not available.
      ParseException - If the field contains unexpected or illegal value.

    • getDirectionOfVariation

      CompassPoint getDirectionOfVariation()
      Get the direction of magnetic variation; east or west.
      返回:
      Direction.EAST or Direction.WEST
      抛出:
      DataNotAvailableException - If the data is not available.
      ParseException - If the field contains unexpected or illegal value.

    • getMode

      FaaMode getMode()
      Get the FAA operating mode for GPS.
      返回:
      FaaMode enum
      抛出:
      DataNotAvailableException - If the data is not available.
      ParseException - If the field contains unexpected or illegal value.

    • getNavStatus

      NavStatus getNavStatus()
      Get the Navigation Status.
      返回:
      NavStatus enum

    • getSpeed

      double getSpeed()
      Get current speed over ground (SOG).
      返回:
      Speed in knots (nautical miles per hour).
      抛出:
      DataNotAvailableException - If the data is not available.
      ParseException - If the field contains unexpected or illegal value.

    • getStatus

      DataStatus getStatus()
      Gets the data status, valid or invalid.
      返回:
      DataStatus.ACTIVE or DataStatus.VOID
      抛出:
      DataNotAvailableException - If the data is not available.
      ParseException - If the field contains unexpected or illegal value.

    • getVariation

      double getVariation()
      Get the magnetic variation. Easterly variation subtracts from true course, and is thus returned as negative value. Otherwise, the value is positive.
      返回:
      Magnetic variation in degrees
      抛出:
      DataNotAvailableException - If the data is not available.
      ParseException - If the field contains unexpected or illegal value.

      cog - True course in degrees

    • setDirectionOfVariation

      void setDirectionOfVariation(CompassPoint dir)
      Set the direction of magnetic variation, east or west.
