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
