I'm switched to using this model now instead: https://www.grc.nasa.gov/www/k-12/VirtualAero/BottleRocket/airplane/atmosmet.html. But it only measures atmospheric density in the lower altitudes i.e. stratosphere and troposphere. So I set a cutoff to neglected atmospheric effects when altitude > 50000m |

If it just reports 0 when >50km that's useless to us. We're interested primarily in 100-600 km, where density is on the order of 10^-6 to 10^-14 kg/m3. I know that might seem pointless to model but it's a constant energy dissipation so over long periods we need to account for it. Check out NRLMSIS or USSA76. Both should have packages already made in Python so you don't have to hand-code the whole model. |
