PROBA2 related ancillary data including orbit, attitude and instrument frames are available in SPICE format, as typically used for planetary missions and maintained by JPL’s NAIF team. Be aware that the PROBA2 related kernels are produced and maintained by the PROBA2 Science Centre. In case of questions, comments, improvements, etc, please contact the PROBA2 Science Center.
The set of kernels that are provided at http://proba2.sidc.be/aux/data/spic… are complete. This means that as a typical user of SPICE and working with PROBA2, you do not need any other kernels on top of the provided ones.
The kernels themselves contain a minimal set of information, but in case of questions, do not hesitate to contact the PROBA2 Science Center directly.
