In-line with the roadmap to autonomy in future, SHI has developed an autonomous navigation system, SAS, which integrates the current navigation system such as ECIDS, RADAR, autopilot w/TCS[Track Control System], and BMS with the additional our own developed 3D around-view vision system, SVISION®. It is hoped that SAS can be used a decision-making-supporting system to increase the safety and to reduce the human errors even before when the autonomy can be accepted.
