The "niek-ephem" tool is a C++ front end to JPL"s DE405 ephemeris.
It includes:
(1) A conversion utility to change JPL"s ASCII interpolation coefficient files to a single binary file.
(2) An interactive text-based interface to the ephemeris information.
(3) A library interface to the ephemeris information.
(4) A unit testing framework.
The correctness of the implementation has been verified using the JPL Horizons web-based ephemeris system.
