Does anybody in the community have examples of atmosphere error models that they can share? Can Orolia provide any templates or examples of this directly in Skydel?

Hi @G-Man,

We already have a few models built-in Skydel and we just released NeQuick model.  
Here is a list of the atmosphere models we now have in Slydel:

**Tropospheric model** :  
Stanag, Saastamoinen, DO-229

**Ionospheric model:**  
Klobuchar, Spacecraft, NeQuick

Are you looking for a specific model?

Best regards,  
Grace
