Class GPSScale

java.lang.Object
  org.orekit.time.GPSScale

All Implemented Interfaces:

java.io.Serializable, TimeScale

public class GPSScale
extends java.lang.Object
implements TimeScale

GPS time scale.

By convention, TGPS = TAI - 19 s.

This is intended to be accessed thanks to the TimeScalesFactory class, so there is no public constructor.
