% Computes patched conic elements. Calculates the planet centric hyperbolic elements. a is in consistent units with mu and vInf. Given any vInf, you can find the elements that pass through rP. Type PatchedConicElements for a demo. -------------------------------------------------------------------------- Form: [a, e, phiL] = PatchedConicElements( vInf, rP, mu ) -------------------------------------------------------------------------- ------ Inputs ------ vInf (1,1) Velocity at the sphere of influence rP (1,1) Periapsis mu (1,1) Planet gravitational parameter ------- Outputs ------- a (1,1) Semi-major axis e (1,1) Eccentricity phiL (1,1) Limiting true anomaly (rad) -------------------------------------------------------------------------- Reference: Allman, M. C. and V. R. Bond, "Modern Astrodynamics," Princeton University Press, 1996,p. 94. --------------------------------------------------------------------------
