This data set contains instrument raw data from the Navigation Camera         
(NavCam) onboard the ROSETTA spacecraft (S/C) from the Prelanding Phase.      
The time interval starts on Aug, 1st 2014 and ends on Sep, 2nd 2014.          
From May 2014, NAVCAM has begun to take regular images, starting with 5 per   
day and with an increasing rate. From July 30th, the Navcam images were taken 
one image every 30 minutes, during the comet approach sequence. From Aug 1st  
to Aug 22nd, the frequency of the navigation slots was of once per hour. Then,
until Sep 2nd, one 2x2 raster with four images was taken every four 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.

files for each file conform to the PDS / PSA guidelines.
