ELP/MPP02 Lunar Ephemeris (JavaScript Version)


ELP/MPP02 is a semi-analytic solution for the lunar motion developed by J. Chapront and G. Francou in 2002. It is an improvement of the ELP2000-82B lunar theory.

Source paper: The lunar theory ELP revisited. Introduction of new planetary perturbations by J. Chapront and G. Francou, Astronomy and Astrophysics, v.404, p.735-742 (2003).

This page provides a JavaScript version of the code. It is generated by my C++ code ElpMpp_JavaScript.h, available on my GitHub page. My C++ code is based on the authors' FORTRAN source code and data files on ftp://cyrano-se.obspm.fr/pub/2_lunar_solutions/2_elpmpp02/.

This page provides a simple platform to calculate the ELP/MPP02 series. It is intended for code test.
