public class JPLCelestialBodyLoader
extends AbstractJPLCelestialBodyLoader

Loader for JPL ephemerides binary files (DE 4xx and BSP) and similar formats (INPOP 06/08/10). It loads the whole CelestialPoint. For CelestialBodyEphemeris loader only, see dedicated class.

JPL ephemerides binary files contain ephemerides for all solar system planets.

The JPL ephemerides binary files are recognized thanks to their base names, which must match the pattern [lu]nx[mp]####.ddd (or [lu]nx[mp]####.ddd.gz for gzip-compressed files) where # stands for a digit character and where ddd is an ephemeris type (typically 405 or 406).

Currently accepted JPL formats are: DE200/DE 202/DE 403/DE 405/DE 406/DE 410/DE 413/DE 414/DE 418/DE 421/DE 422/DE 423/DE 430 and BSP.

The loader supports files encoded in big-endian as well as in little-endian notation. Usually, big-endian files are named unx[mp]####.ddd, while little-endian files are named lnx[mp]####.ddd.

The IMCCE ephemerides binary files are recognized thanks to their base names, which must match the pattern inpop*.dat (or inpop*.dat.gz for gzip-compressed files) where * stands for any string.

Currently accepted IMCCE formats are: INPOP 06b/06c/08a/10a/10b/10e/13c/17a/19a.

The loader supports files encoded in big-endian as well as in little-endian notation. Usually, big-endian files contain bigendian in their names, while little-endian files contain littleendian in their names.

The loader supports files in TDB or TCB time scales.

Note: the time scale isn't serialized.
