Path: Orbit/RHSOrbit
% High fidelity orbit model right-hand-side. Includes higher harmonics of the earth's gravitational field and sun and moon accelerations as options. - The drag option = drag coefficient * area / mass where the area is in m^2 - The sun option = area / mass - The moon option is 0 or 1 The gravity model should be unnormalized. -------------------------------------------------------------------------- Form: xDot = FOrbHF( x, t, options, jD, aExt, mu, s, c, j, a ) xDot = FOrbHF( x, t, options, jD, aExt, d ) xDot = FOrbHF( t, x, options, jD, aExt, mu, s, c, j, a ) (for ode113) -------------------------------------------------------------------------- ------ Inputs ------ x (6,1) The state vector [x;y;z;dx/dt;dy/dt;dz/dt] t (1,1) Time options (1,5) [Highest zonal harmonic,Highest tesseral harmonic, Sun,Moon,Drag] jD Julian date aExt (3,1) External acceleration vector [x;y;z] ECI d (.) Gravity model struct, unnormalized - or - mu Spherical gravitational potential s (36,36) S terms c (36,36) C terms j (36) m = 0 terms a Earth radius ------- Outputs ------- xDot (6,1) The derivative of the state state vector -------------------------------------------------------------------------- See also AGravity, APlanet, AtmDens2, SolarF, and FOrb. --------------------------------------------------------------------------
