… ECLIPJ2k, but I can't seem to convert it correctly to what I need.
…t know how I can solve data generated via Meeus
… ephemerides... Not reassuring in the least bit.
…ous set and this, but now I cannot invert R after 10 predictions. Same issue happens with a local copy of the code and binary. I can only suspect it's an ephemeride issue, but I really don't know WTF is going on.
…e RMS are still horribly large (6 million km in position). I'll try to switch to a CKF but I don't expect this to be any better, the issue must lie in my dynamics
… to Prof. McMahon, the issue may very well be a case of garbage in and garbage out: StatOD is very sensitive to small changes (e.g. going from the de431 to de430 SPICE kernel would break things). Therefore trying to re-fit Meeus into my code designed around and for the SPICE frames is problematic at best.

WARNING: Meeus does not seem to be in the same frame as what SPICE returns. The Meeus results were compared with those emanating from a Matlab script, and they match (I should probably add those to the tests actually).
However, one should not use this implementation of the Meeus algorithms for perturbation: I surely have a frame issue somewhere which leads to the propagated state being very different from the truth.
