This library is designed to access the binary planetary ephemeris files, such INPOPxx, JPL DExxx and SPICE ephemeris files.
This library provides a C Application Programming Interface (API) and, optionally, Fortran 77/2003, Python 2/3 and octave/Matlab interfaces to be called by the application.
This software is an open-source product distributed under three distinct licenses giving you the choice of one of the three following sets of free software/open source licensing terms. This allows the use of our code in as wide a variety of software projects as possible.
This software is governed by the CECILL-C, CECILL-B or CECILL version 2.1 license under French law and abiding by the rules of distribution of free software. You can use, modify and/or redistribute the software under the terms of the CeCILL-C, CeCILL-B or CeCILL license as circulated by CEA, CNRS and INRIA at the following URL https://cecill.info/.
