The time interval starts on September, 23rd 2014 and ends on October, 24th 2014. The frequency of the navigation slots is of on 2x2 raster with 4 images every 4 hours. Onboard the Rosetta Orbiter (RO) there are two identical NavCams, providing complete redundancy, in the event of Single Point Failure (SPF). Each NavCam unit consits of a Camera Baffle (CAM-BAF), Camera Optical Head (CAM-OH) and a Camera Electronics Unit (CAM-EU) and is capable of providing multiple operating modes to fully satisfy the requirements of the Rosetta mission with respect to the autonomous tracking and attitude determination. ============================================================================== PRL-MTP008 NavCam Data Archive: ============================================================================== a) S/C Data ========================= CODMAC Level / Type Data Type Data Content 2 / EDITED Data Image RAW TM of IMAGE and HK Data The data can be found in the following directory: */DATA/ The data products are in the form of RAW images each with a detached label. b) Supporting Files ========================= Supporting files for the Archive end user include PDS: documentation, descriptions and searchable indices.
