Table 1. MOSAM-SYSTEM PARAMETERS 
Block 5 is the Management Interface of the system realised on 
IEEE-1394 with 200/400 Mbit/s transfer rate. 
Block 6 is based on Silicon Graphics platfonn. 
Block 7 - Mission Control is the interface to Block 8 - Service 
Navigation systems for receiving online the GPS and the 
navigation control data. 
The modular organization of the system architecture allows 
independent tests, calibration and performance of the different 
sensors and gives full flexibility for different modes of operation 
of the system according to the different applications. 
4. PRELIMINARY STUDIES AND EXPERIMENTS, 
PROCESSING AND ANALYSIS OF RESULTS 
In order to specify and optimise the parameters and the 
characteristics of the system a plan was worked out for 
preliminary activities and experiments, which have to confirm 
the justification of the selected architecture of the system and to 
provide preliminary estimates on the possibility of solving the 
defined tasks. 
The main parameters of this programme are: 
- selection of typical areas for study of performance: 
- preliminary preparation and collection of additional 
information; 
- tests on board of an AN-30 aircraft of the panchromatic CCD 
camera TC217 prototype; 
- tests on board of an AN-30 aircraft of the video-spectrometer 
prototype for the visible range (VS-Vis512); 
- Ground-based tests with FPA (Focal Plane Array) camera for 
VS-MIR spectrometer (range 3-5 pm); 
4.1 Selection of geographical areas 
In agreement with the tasks mentioned in section 2.1 and after 
detailed preliminary analysis and discussions with colleagues 
from the Environmental protection chair of the Biological 
Faculty of the Sofia University and from the Laboratory on 
remote sensing applications in geology' of the Geology and Ore 
Exploration chair of the Mining Geological University of Sofia, 
two geographical sites were defined on the Bulgarian territory,
