SATURN Project - Phase 1

CHALLENGES

Main challenges of the project are related to the management of:

• Sea states and induced mobility to the ship
• Marine environment
• Satellite link budget

The sea state causes a complex ship motion on the three axes roll, pitch and yaw. The motion depends on the ship tonnage, length, specific design of the skull and overboard structures.
Motions around the roll axis are mostly caused by the sea waves, followed by the pitch motions and by the yaw motion.

The marine environment is characterized by salinity, rain, high air moisture content and strong winds, which are all causes of potential damages to the externally exposed hardware.

The link budget of the S-band satellite channel on the sea requires an antenna with higher gain than on terrestrial, with a robust pointing system and S-MIM standard compliancy.
