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

Latest stable version
- Version 3.4.0 (August 2019)
Octave package calcephoct-3.4.0.tar.gz
- Add the function calceph_isthreadsafe.
- Multiple threads can now access the same ephemeris descriptor if the function calceph_isthreadsafe returns 1. Fortran and C examples (f2003parallel.f, cparallel.c), written using OpenMP, are available in the folder examples.
- Fix an error if multiple SPICE kernels are loaded for the same objects over different time-span.
- Fix the MinGW Makefiles if the variable MAKE contains spaces.
- Support the segment 5 and 18 in the SPICE kernel file.
- Support the euler angles for the orientation stored in a text PCK files (BODY..._POLE_RA, BODY..._POLE_DE, BODY..._POLE_PM, BODY..._NUT_PREC_...).
- Support the frame 17 (ECLIPJ2000) in the SPICE kernel file.
- Add the utilities calceph_queryposition and calceph_queryorientation.
