% Magnetic field based on the Mead-Fairfield Model. Computes the field as a dipole with deviations. Has a built-in demo for geo orbit. -------------------------------------------------------------------------- Form: [bT, dB] = BMF( r, jD, kP ) -------------------------------------------------------------------------- ------ Inputs ------ r (3,n) Location in ECI Frame. jD (1,n) Julian dates kP (1,1) Solar activity index ( Typically 0 to 3 ) ------- Outputs ------- bT (3,n) Magnetic field ECI (T) dB (3,n) Delta magnetic field ECI (T) -------------------------------------------------------------------------- Reference: Mead, G.D., Fairfield, D.H.
