% Propagate a Sun-Earth-Moon 4BP with origin at the Earth-Moon barycenter. These are dimensional equations (mks) that use the JPL planetary ephemerides. PlanetPositionEMBarycenter must be initialized with the sun, planet, and moon, as in PlanetPositionEMBarycenter('initialize',[0 3 10]); -------------------------------------------------------------------------- Form: [yvec, tvec] = Propagate4BP(y,t0,tF,jDate,stmcalc,acc) -------------------------------------------------------------------------- ------ Inputs ------ y (6,1) Current state vector [r;v] t0 (1,1) Initial time tF (1,1) Final time jDate (1,1) Julian date stmcalc (1,1) 1 if propagating the STM, 0 otherwise acc (1,1) 1 if there is thrust, 0 if ballistic muMoonMultiplier (1,1) 0 to 1, for the purpose of easing between 3BP and 4BP ------- Outputs ------- yvec (6,:) State vector tvec (1,:) Time vector -------------------------------------------------------------------------- See also: PlanetPositionEMBarycenter, Propagate3BP --------------------------------------------------------------------------
