– Compare your MATLAB outputs against the official CIRA-2012 reference tables. Off-by errors in the exospheric temperature equation are common in amateur translations. Beyond JB2008: What Comes Next? JB2008 remains the gold standard for operational drag modeling, but it is empirical—it fits historical data rather than simulating physics. Newer models like HASDM (High Accuracy Satellite Drag Model) and TIEGCM (thermosphere-ionosphere GCM) offer higher fidelity, but they require supercomputing resources. jb2008 matlab
