% Atmospheric velocity from position and planetary rate. This routine assumes the Earth rotates perfectly around its z axis. For a higher fidelity result you must compute the Earth-fixed tranformation for a particular date. Has a built-in demo. -------------------------------------------------------------------------- Form: [v, vMag] = VAtm( r, wP ) -------------------------------------------------------------------------- ------ Inputs ------ r (3,:) r in the ECI frame wP (1,1) Planetary rotation rate (rad/sec), default is Earth ------- Outputs ------- v (3,:) v in the ECI frame vMag (1,:) Magnitude -------------------------------------------------------------------------- References: Escobal, P.R., Methods of Orbit Determination, 1976, p. 60. --------------------------------------------------------------------------
