Abstract: A mathematical model for the rendezvous launch window based on the rendezvous multi\|constraints including orbit sunlight constraint, sunlight incidence constraint for optics navigation measurement devices and coplanar constraint is established in this paper. The method and the scheme of the rendezvous launch window were presented and the effects of every constraint on the rendezvous launch window
are analyzed. The sets of annual rendezvous launch windows of both target and chaser under sunlight constraint are constructed. According to two mission programming modes, methods for determining the annual coplanar launch time sets for both target and chaser are also proposed. The day window and the time window of the annual rendezvous launch window sets with multi\|constraints are plainly presented for analysis and programming of the rendezvous launch windows. Simulation computations indicate
that the set of annual rendezvous launch windows is correct and valid. The model, the method and the result for the rendezvous launch window are benefit to analysis and programming of the rendezvous mission.
