The time interval starts on July, 28th 2015 and ends on August, 25th 2015. 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. ============================================================================== ESC2-MTP015 NavCam Data Archive: ============================================================================== a) S/C Data ========================= CODMAC Level / Type Data Type Data Content 2 / EDITED Data Image RAW TM of HK and IMAGE 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 file that contains a cropped version of the Housekeeping (HK) - Telemetry (TM) information. b) Supporting Files ========================= Supporting files for the Archive end user include PDS: documentation, descriptions and searchable indices. These are organised into three sub- directories immediately below the root directory: - CATALOG - DOCUMENT - INDEX ============================================================================== Structure of the Volume: ============================================================================== Root Directory | |--- AAREADME.TXT (PDS required introduction to the data set ) | |../BROWSE/ | | | |--- BROWINFO.TXT (List of the BROWSE folder contents) | | | |../CAM1/ | | | | | |--- *.JPG Files (Thumbnail of each data product: JPEG format) | | |--- *.LBL Files (Detached label file for each browse product) | | = | | | |../CAM2/ | | | | = |--- *.JPG Files (Thumbnail of each data product: JPEG format) | |--- *.LBL Files (Detached label file for each browse product) | = | |../CATALOG/ | | | |--- CATINFO.TXT (List of the CATALOG folder contents) | |--- *.CAT Files | = | |../DATA/ | | | |../CAM1/ | | | | | |--- *.IMG Files (Data products in IMAGE format) | | |--- *.LBL Files (Detached label files for each data product) | | |---*F.FIT Files (FITS format files) | | |-- *F.LBL Files (Label of the FIT files) | | = | | | |../CAM2/ | | |--- *.IMG Files (Data products in IMAGE format) | | |--- *.LBL Files (Detached label files for each data product) | | |---*F.FIT Files (FITS format files) | | |-- *F.LBL Files (Label of the FIT files) | = | |../DOCUMENT/ | | | |--- DOCINFO.TXT (List of the DOCUMENT folder contents) | |--- RO-SGS-IF-0001.TXT Files (ASCII version of EAICD) | |--- RO-SGS-IF-0001.PDF Files (PDF version of EAICD) | |--- RO-SGS-IF-0001.LBL Files (EAICD label) | |--- ERRATA.TXT (List of known errors and extra notes on the volume) | |../INDEX | | | |--- INDXINFO.TXT (List of the INDEX folder contents) | |--- INDEX.LBL (Detached label file for INDEX.TAB) | |--- INDEX.TAB (Index of the data set in tabular format) | |--- BROWSE_INDEX.TAB (Index of the browse products) | |--- BROWSE_INDEX.LBL (Detached label for the browse index) | = The ROSETTA project decided that the data would be archived in the PDS Version 3 format and, consequently, the layout of this volume and all associated label files for each file conform to the PDS / PSA guidelines. ============================================================================== Contact Information: ============================================================================== Data generated by: Bernhard Geiger SRE-OO ESAC, P.O.
