$P$	Orbit parameter, $p=a\cdot (1-\epsilon ^{2})$
$u$	corrected true anomaly, $u=\omega +\varphi$
$R_{E}$	mean planetary radius
$J_{2}$	non spherical gravity term
$i$	inclination
$\omega$	Argument of perigee
$\epsilon$	eccentricity

${\frac {d\Omega }{du}}=-3\cdot J_{2}\cdot ({\frac {R_{E}}{p}})\cdot \sin ^{2}{u}\cdot \cos {i}\cdot [1+\epsilon \cdot \cos {u-\omega }]$
