Class H0MinusNFrame

java.lang.Object
  org.orekit.frames.Frame
      org.orekit.frames.H0MinusNFrame

All Implemented Interfaces:

Serializable

public class H0MinusNFrame
extends Frame

"H0 - n" reference frame.

The "H0 - n" frame is a pseudo-inertial frame, built from the GCRF-ITRF transformation at the date H0 - n; this transformation is "frozen" in time, and it is combined to a rotation of an angle "longitude" around the Z axis of the ITRF frame.

Its parent frame is the GCRF frame.

Since:

3.4
