Class ReentryParameters

java.lang.Object
  org.orekit.orbits.orbitalparameters.AbstractOrbitalParameters
      org.orekit.orbits.orbitalparameters.ReentryParameters

All Implemented Interfaces:

Serializable, IOrbitalParameters

public class ReentryParameters
extends AbstractOrbitalParameters

This class handles reentry parameters.

The parameters used internally are the following elements:

     altitude (m)
     latitude (m)
     longitude (m)
     velocity (m/s)
     slope of velocity (rad)
     azimuth of velocity (rad)
   

2 more parameters defining the central body are added:

      equatorial radius (m)
      flattening
  

Since:

3.0
