Introduction to dynamical systems: orbits and phase portraits, invariant manifolds, center manifold in finite dimension. Example of a dynamical system which has an $\omega$-limit which is a cylinder of closed orbits. For orbits with very low inclination where the location of the ascending node is difficult to determine (since it's the intersection between two almost parallel planes), we instead use the longitude of periapsis $\varpi = \Omega + \omega$. Leapfrog integrator By alternating kick and drift steps in more elab-orate sequences, we can construct higher-order integrators (Yoshida 1993); these are automatically symplectic since they are the composition of maps (the kick and drift steps) that are symplectic. Gravity keeps the planets in their orbitsD. Build your own system of heavenly bodies and watch the gravitational ballet. The online version of Numerical Recipes in c is here. Also in Python, names in UPPER_SNAKE_CASE denote that they refer to a constant value, so instead of g_const, GRAVITY denoting a constant value seems clearer to me. Orbits in 2D. It has its perihelion at the lift-off point L and its aphelion at the rendezvous point R. We expect numerical integration algorithms to be reliable and their output to be consistent with other means of analyzing the properties of vector elds. On the other hand, high-inclination satellites don't receive much benefit from equatorial launch sites. All the hard work is done by Brandon Rhodes implementation of SGP4.
