The study on helicopter route planning

Route planning is a very important part in simulation system. Under a simulated circumstance, the simulation can be improved if we can plan a reasonable flight path. This paper studies the helicopter route planning in hilly terrain. The whole route planning is divided into two levels. Firstly, the reference trajectory was planned, then replan parts of them, according to the changes in the environment (such as the emergence of new threats), and the others still in their track. Finally, on the platform of MATLAB, simulated the algorithm and the algorithm validity can be verified.
