The high-fidelity drag coefficient response surface models were finally approved for public release by LANL. The models go with the article ”Mehta et al., Modeling satellite drag coefficients with response surfaces, Advances in Space Research 54 (2014) 1590-1607”. Attached zip file includes models for the CHAMP and GRACE satellite. The file can also be downloaded at If you have questions, please do not hesitate to contact me at You can also contact the author at the above email if you want models developed for your specific satellite or space object. Please share the link and code with any colleagues that maybe interested.
