- Summary
- Information wanted on three-body solvers, and on high inclination coorbitals

I was working on a proposal for a spacecraft, and suddenly realised that the ideal orbit may be a high inclination type of near-Earth coorbital called a "retrograde satellite" or RS orbit. Do you know of:

* A person who can compute 100 years of coorbital stability using three body (sun, earth, satellite) or four body (with moon) kinematics?

* A simple-to-use approximate 3-D calculator for the three body problem, simplified so the third body has negligible mass.

* Where I can find as much information as possible on RS orbits in general. eg. ellipticity vs inclination.

* Any information at all on periodic RS orbits with 1:1 resonance.

So far, all I know about RS orbits comes from "Coorbital Dynamics at Large Eccentricity and Inclination ", https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.83.2506

The inclination range I'm most interested in is 15 to 45 degrees.
