Path planning based on ant colony and genetic fusion algorithm for communication supporting spacecraft
To implement the orbit maneuvering of a communication supporting spacecraft in a large area
the path planning of the communication supporting spacecraft was proposed based on the fusion of ant colony and genetic algorithms. Firstly
the orbit dynamic model of spacecraft was established
and the fusion scheme of the genetic and ant colony algorithms was studied. On the basis of the fast convergence of genetic algorithm and the higher efficiency of colony algorithm
the genetic and ant colony algorithms were redesigned respectively under a fusion framework
and the operation process was presented. Finally
the path planning was simulated. The simulation results show that the fusion algorithm can reach the stabilization after 100 iterations
and the average safety path length is 4.055 3104 m. These results prove that the convergence speed of maneuvering orbit planning based on genetic and ant colony fusion is fast
and the flight path to a fault of spacecraft can be obtained in a shorter time
which raises the efficiency of orbit planning remarkably. Key words: path planning; genetic algorithm; ant colony algorithm; orbital maneuvering; communication supporting spacecraft
