This directory contains the following JWST SPK files: jwst_rec.bsp contains continuous JWST reconstructed trajectory based on definitive ephemerides delivered by the Flight Dynamic Facility (FDF) group, GSFC to the DSN SPS portal, from which they are retrieved and merged together to produce this file by Jon Giorgini, the Solar System Dynamics (SSD) group, JPL. This SPK covers from the separation epoch through the end of the latest definitive ephemeris file available in SPS. It contains data only for JWST. jwst_pred.bsp contains continuous JWST predicted trajectory based on predicted ephemerides delivered by the Flight Dynamic Facility (FDF) group, GSFC to the DSN SPS portal, from which they are retrieved and merged together to produce this file by Jon Giorgini, the Solar System Dynamics (SSD) group, JPL. This SPK covers from the separation epoch through the end of the latest predicted ephemeris file available in SPS, approximately 1 year forward from the current date. It contains data only for JWST. Please see internal SPK comments for more details about these files. The release of these JWST observatory ephemerides via the NAIF server to the science community to facilitate their proposal and observation planning has been authorized by the JWST Operations Project.
