Method Summary

Orbit	osc2mean(Orbit orbit) Convert provided osculating orbit into mean elements.
Orbit	propagateMeanOrbit(AbsoluteDate date) Propagate mean orbit until provided date.

Method Detail

osc2mean

Orbit osc2mean(Orbit orbit)
               throws OrekitException

Convert provided osculating orbit into mean elements.

Warning: Used algorithm often consists in an iterative algorithm with a convergence criterion. As a result convergence is not always ensured, depending on the underlying theory.

Parameters:

orbit - an orbit (osculating elements)

Returns:

mean elements of provided orbit

Throws:

OrekitException - if conversion fails

mean2osc

Orbit mean2osc(Orbit orbit)
               throws OrekitException

Convert provided mean orbit into osculating elements.

Parameters:

orbit - an orbit (mean elements)

Returns:

osculating elements of provided orbit

Throws:

OrekitException - if conversion fails

propagateMeanOrbit

Orbit propagateMeanOrbit(AbsoluteDate date)
                         throws OrekitException

Propagate mean orbit until provided date.

Parameters:

date - a date

Returns:

mean orbit at provided date

Throws:

OrekitException - thrown if computation failed
