Abstract: An autonomous navigation system and method for a maneuverable platform are provided herein. The method may include: obtaining a plurality of objectives relating to a maneuverable platform; determining a plurality of options of direction and speed for the platform; autonomously selecting, one option of the plurality of options, in order to achieve said objectives, by calculating a weighted grade of each option based on the weights of the objectives and said grading scheme; and periodically repeating: the receiving with updated platform and obstacles data and the autonomously selecting with the updated platform and obstacles data, wherein the autonomously selecting is executed by a computer processor and includes, for each obstacle, calculating projected positions of the platform and of that obstacle to determine the distance between the platform and the obstacle at the closest point of approach and estimated time to arrive to the closest point of approach.
