Abstract
A method is provided for planning a trajectory to be performed by a marine vessel between a first point and a second point, the trajectory having a first path and a second path. The method includes a first step (202) of computing a theoretical trajectory in a ground reference frame from the first point to the second point assuming an absence of water current, the theoretical trajectory comprising a first theoretical path and a second theoretical path. A second step (204) includes computing a second path in the ground reference frame, and a third step includes (206) computing a corrected first path in a water reference. A fourth step includes (208) computing the trajectory in the ground reference frame from the first point to the second point based on the corrected first path and the second path.
