Path: Interplanetary/InterplanetaryOrbit
% Initialize a heliocentric orbit from a planet centered orbit. xP is in the ECI planet centered frame. Type HelioFromPlanetInit for a demo of an equatorial 7000 km circular earth orbit. This only works with the planets (including Pluto). It uses the low-fidelity almanac functions. -------------------------------------------------------------------------- Forms: xH = HelioFromPlanetInit( planet, xP, jD ) -------------------------------------------------------------------------- ------ Inputs ------ name (1,1) Planet name xP (6,1) State in the planet centered ECI frame jD (1,1) Julian date ------- Outputs ------- xH (6,1) State in the heliocentric frame --------------------------------------------------------------------------
