Path: SpacecraftEstimation/OpticalNavigation
% Generate a trajectory for optical navigation in the Earth-Moon system The spacecraft is an elliptical Earth orbit that passes behind the moon. The timing is set so that the spacecraft should be behind the moon in time for an orbit entry burn. At that point the simulation switches times scales and puts the spacecraft in a lunar orbit. You will notice that the moon fills the entire camera field of view at that point. You use the magnifying tool to look at the lunar orbit. This can be hard to do until the sim stops. This simulation creates 1000 points. The time scale in the lunar transfer orbit is the orbit period divided by n. The lunar time scale is dTL seconds. This simulation is slow but you can save the position vectors for use in optical navigation studies. The simulation is in the ECI frame. Saves a results file called EarthMoonTraj. ------------------------------------------------------------------------- See also: Constant, TwoObjectTrajectoryViewer, RPRA2AE, Period, Date2JD, MoonECIElements, RVOrbGen, NavigationCamera, StarCameraViewer, DispWithTitle, LunarOrbitInsertion, RV2El, Mag, Unit, U2Q, TimeLabl, Plot2D, PlotPlanetaryOrbit -------------------------------------------------------------------------
