Package org.orekit.gnss.attitude

Class BeidouIGSO

java.lang.Object

org.orekit.gnss.attitude.BeidouMeo

org.orekit.gnss.attitude.BeidouIGSO

All Implemented Interfaces:

AttitudeProvider, GNSSAttitudeProvider

public class BeidouIGSO
extends BeidouMeo

Attitude providers for Beidou inclined geosynchronous orbit navigation satellites.

This mode is in fact similar to Beidou MEO, hence the class simply inherit for BeidouMeo without any change.

Since:

9.2

Constructor Detail

BeidouIGSO

public BeidouIGSO(AbsoluteDate validityStart,
                  AbsoluteDate validityEnd,
                  ExtendedPVCoordinatesProvider sun,
                  Frame inertialFrame)

Simple constructor.

Parameters:

validityStart - start of validity for this provider
