% Computes the geocentric magnetic field based on a tilted dipole model. The output is in geocentric inertial coordinates (ECI). This function includes the effect of dipole motion on the earth. Type BDipole for a demonstration of a satellite in a low earth inclined orbit. -------------------------------------------------------------------------- Form: [b, bDot] = BDipole( r, jD, v ) -------------------------------------------------------------------------- ------ Inputs ------ r (3,:) Position vector in the ECI frame (km) jD (1,:) Julian days v (3,:) Velocity (km/s) ------- Outputs ------- b (3,:) Magnetic field in the ECI frame (T) bDot (3,:) Derivative of b in the ECI frame (T/s) -------------------------------------------------------------------------- Reference: Wertz, J., ed. "Spacecraft Attitude Determination and Control," Kluwer, 1976, 783-784. Includes 1995 IGRF coefficients as of Jan. 1999 --------------------------------------------------------------------------
