Using the NAIF/SPICE System to Generate Navigation Files

Kurzfassung

SPICE is a NASA information system for assembling, archiving, distributing and accessing geometric and related ancillary information used to interpret space science data. A short overview is given over the installation on the Alpha VAX of DLR/GSOC and the general usage of the routines is described as far as they are of interest of the generation of navigation interface files for photogrammetric restitution of HRSC and the WAOSS images taken in the framework of the MARS 96 mission. More specifically the interface of orbit & attitude information and photogrammetric restitution is realized by ORBINPBA and ATTINPBA files that are generated out of SPICE kernels making use of the programs HWSK2ORB and HWCK2ATT. Furthermore the results of photogrammmatic restitution as far as the exterior orientation is concerned is provided by ORBOUTBA and ATTOUTBA files, that may be reconverted to SPICE kernels using the programs HWORB2SK and HWATT2CK. This document describes the concept, usage and formats of the relevant programs and therefore serves as a users guide.
