9.2 Navigation
The second category for the 2024 competition is Navigation. The vessel will receive 2 GPS points which the vessel must safely navigate between. In the more complex challenges, the vessel must navigate the waters according to the sea markers. Different types of navigational sea markers will be utilized.
The task demonstrates the vessels' ability to navigate within any given pathway. Contact with the sea markers should be avoided, and the vessel should stay within the pathway throughout the entire course. Note that the vessel must be able to interpret cardinal markers and navigate accordingly.
Task 2
OBJECTIVE
The ASV will line up at GPS point 3 and face all different cardinal markers inside a straight channel of red and green gates. The cardinal markers provide information on what side to pass the buoy and avoid danger, while moving towards the end at GPS point 4.

TASK GUIDELINE
Step 1:
Once given the go-ahead from the chief marshall, you must again activate Autonomous Mode, and your ASV may start its attempt at task 4. Your turn starts when the ASV crosses the first gate.
Step 2:
Once you pass the final gate of task 4, your attempt finishes. Then your ASV shall stop at GPS-point 10 and stay stationary there. You may switch to Remote Control
Step 3:
When the Chief Marshall gives the go-ahead, you may steer the ASV safely back to the dock in Remote Control.
