% Load a set of historical NORAD elements and convert to Cartesian states. Calls NORAD. May take a few minutes for very long files. See http://celestrak.com/NORAD/archives/ for historical data sets. This function has a built-in demo using historical data for Mir. -------------------------------------------------------------------------- Form: [r, v, jD, s, x] = LoadNORAD( fName, model, kMax ) -------------------------------------------------------------------------- ------ Inputs ------ fName (:) File name model (:) Propagation model, SGP, SGP4, etc. kMax (1,1) Maximum number of points to get ------- Outputs ------- r (3,:) Position vectors v (3,:) Velocity vectors jD (1,:) Epoch, in Julian date s {:} Cell array of element set strings x (:) Data structure of NORAD info --------------------------------------------------------------------------
