The time interval starts on June, 28th 2016 and ends on July, 26th 2016. The frequency of the navigation slots is of one 2x2 raster with four images every five hours. This nominal frequency can be interrupted by manoeuvres. 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. ============================================================================== EXT3-MTP031 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.
