Background

The preliminary layout of the ES housing consist of a common electronics box both

for LEO and GEO sensor, in front of an interchangeable LEO and GEO optical head.

Since LEO optical assembly dimensions are quite larger than GEO ones, the preliminary

housing layout has been dimensioned upon LEO optical assembly. Traditional materials

and production technologies shall be privileged thought the use of composites, in

particular carbon-fiber, for the optical housing may grant better structural performances.

Carbon-fiber optical housing could be a valid alternative to standard aluminum and shall

be considered in case of high overall weight due to aluminum use.

The selected preliminary configuration provides a common electronics enclosure both

for LEO and GEO sensor, in front of an interchangeable optical head. Thanks to this

solution the electronic board is the same both for LEO (Figure 18) and GEO (Figure19)

optics ensuring modularity and reliability. The bottom of the sensor act as interface with

the spacecraft providing power and data connector(s) and an additional electronics bay for

additional plug-in boards integration. Thus it is possible to increase sensor capabilities

simply by adding compatible interface, data elaboration and data storage units inside the

electronics bay.
