Abstract: The space defence three-player problem with impulsive thrust is studied in this work. Interceptor spacecraft and anti-interceptor spacecraft have only one chance to manoeuvre while target spacecraft just keeps running in the target orbit without the ability to manoeuvre. Based on Lambert theorem, space defence three-player problem is modelled and divided into two layers. The internal layer is interception problem that interceptor spacecraft tries to intercept target spacecraft. The external layer is anti-interception problem that anti-interceptor spacecraft tries to defend against interceptor spacecraft. Because it can get the global solution and does not need the gradient information which is required in traditional optimisation methods, the genetic algorithm is employed to solve the resulting parameter optimisation problem in interception/anti-interception problem. Numerical simulation is provided to verify the availability of the obtained solution, and the results show that this work is useful to some practical applications.
