Abstract
To address the demand for temporal coordination of exoatmospheric vehicles,this paper investigates time-of-flight(TOF)constraint methods and proposes a calculation method for required velocity under trajectory TOF constraints.Firstly,based on the analytical solutions of free-flight trajectories and principles of orbital dynamics,elliptical orbits constrained by TOF are derived.Building on this foundation,a computational approach for the required velocity vector in the launch inertial coordinate system is developed.Furthermore,by considering J2 perturbation effects,a correction method for orbital parameters and velocity vectors is presented.Numerical simulations demonstrate that the proposed velocity vector calculation method achieves high temporal control accuracy,effectively satisfying exoatmospheric coordination requirements for vehicles under both co-located and geographically dispersed launch conditions.关键词
