Observation Geometry System for Space Science Missions

SPICE is an information system the purpose of which is to provide scientist the observation geometry needed to plan scientific observations and to analyze the data returned from those observations. SPICE is comprised of a suite of data files, often called kernels, and software -mostly subroutines. A customer incorporates a few of the subroutines into his/her own program that is built to read SPICE data and compute the needed geometric parameters for whatever task is at hand. Examples of the geometry parameters typically computed are range or altitude, latitude and logitude, phase, incidence and emission angles, instrument pointing calculations, and reference frame conversions. SPICE is also very adept at time conversions.

SPICE was developed and is maintained by the Navigation and Ancillary Information Facility (NAIF) team of the Jet Propulsion Laboratory, California Institude of Technology, under contract with the U.S National Aeronautics and Space Administration (NASA).

You will find in this registry a collection of respositories to host mainly metakernels required for some space mission. They are intented to be used by the planetary-coverage to simplify kernels management for the mission that don't natively provided metakernels.
