Besides the inspection sensors, the vehicle guidance system has
one of the most important roles for a successful mission. It guides
the vehicle and is responsible for autonomous actions.
A mission can be divided into three main stages: planning, execution
and evaluation of the gained data. The autonomous vehicle
guidance and control takes place during the mission execution
stage. During the planning stage all known information have to
be prepared to describe the mission in detail: what has to be inspected,
where is the inspection track, what is the inspection distance
and speed, where the vehicle can be deployed and recovered,
where are dangerous areas for the vehicle, etc. All these points
must be compiled together to make the inspection successful.
Besides the known issues, there are many unknown parts in the
mission execution. There can be obstacles which are not mapped
in the harbor maps. Usually, the desired tracks in the mission plan
are inexact.
Therefore, the VGS must handle the unknown parts on the basis
of the known information and fuse it together to guide the vehicle
safely through its mission.
