Atmosphere model prediction

[SimSim11]

Hi everyone!

I am trying the study the different models of Earth's atmosphere in order to calculate the drag force a spacecraft encounters in LEO.

I came across a number of these models, some of which are empirical ones such as Jacchia series, MSIS series and DTM series models.

Each of these models are based on space weather data which is available online up to a certain date in the past; say 30th January 2018. 

I am having trouble figuring out how to use this date to predict the satellite drag in future dates.  Any suggestions/directions?

Many thanks in advance

Hi,

nice task :-)

I am not a crack for space weather. Example implementations for your models are online, you probably know them:

I can't help you directly with variations derived from momentary space weather https://www.swpc.noaa.gov/models. With the Jacchia model, you'd be fine with temp., density, season, height.

It sounds like you want to go more into detail than the pure atmosphere models compute ...

You probably know this as well: https://omniweb.gsfc.nasa.gov/vitmo/msis_vitmo.html

The model description link seems to be broken ...

 

Not much of a help i fear.
