Third-party Interfaces to SPICE


Some work was done long ago on a NAIF instance of Python wrappers for CSPICE, but there has been no advancement since then. Some SPICE users have made their own, partial versions of a Python-­‐CSPICE interface that they seem willing to freely share. Two of these are as follows.

  • Andrew Annex authored and maintains the Python interface SpiceyPy. SpiceyPy provides a pure idiomatic Python interface for nearly all CSPICE functions and it integrates fully with NumPy. SpiceyPy has been repeatedly vetted and tested both by users and extensive unit test run in a continuous integration service. Precompiled Python wheels and Anaconda packages are available for Linux, MacOS, and Windows platforms for both Python 2.7.x and Python 3.5.x. Installation is as easy as "pip install spiceypy".

  • The PDS' Ring Moons System node managed by Mark Showalter maintains a Python interface to the most widely used CSPICE functions. It also employs standard Python mechanisms for handling CSPICE exceptions. Installation instructions are provided for Mac OS, Windows and Ubuntu Linux.
Probably there are still others: one could inquire about such using the "spice_discussion" Mailman list.


Astrodynamicist Daniel Adamo, using the Swift programming language, has successfully invoked CSPICE functions to obtain state vectors from planetary ephemerides under the MacOS operating system. He has carefully documented his steps in doing this and has graciously provided that information in a white paper. This paper provides techniques and coding examples.
