Introduction
Communication links between space crafts.
Reduce
the number of earth stations.
The
inter orbit link- microwave or optical
technology.
Optical
technology offers a number of
advantages.

3. Advantages Over Microwaves
The
antenna can be much smaller
Optical
beam widths are less.
Very
high antenna gains on both transmit and
receive.
Low
mass, low power terminal.

4. Sout & EDRS- Programs of The European SpaceAgency (SOUT) .
ARTEMIS
& EDRS- Programs of The European
SpaceAgency
SMALL OPTICAL USER TERMINALS
(SOUT) .
has
the features of low mass, small size and
compatibility with SILEX.

5. Design of Sout Two Phases Produce a terminal flight configuration,
perform detailed subsystem design and
modeling.
Build an elegant bread board
