Is an SGP4 propagator provided with "Orbit Propagator" block in Simulink (Aerospace Blockset)

Hi All;

This question may be quite obvious (or perhaps trivial) but I am unable to find a standard SGP4 propagator offered by Orbit Propagator block in Aerospace Blockset. It seems there are commands that can be used in MATLAB, however I am trying to use the Simulink / Orbit Propagator. One would expect to see this option in the drop down menu "Main --> Propagation Methood" and then in the drop down (among "Numerical", "Kepler") select "SGP4" (which is not there) followed by a TLE entry box.

Can you let me know, if "SGP4" propagation is possible with this block?

Thanks

Gökhan

Hello, I understand you want to use the SGP4 propagator method in the “Orbit Propagation Block”.

The method does not seem to be directly supported in the block, however it is possible to implement it through writing the required function inside the “MATLAB Function Block”.

You can refer to the following file exchange for more information on how to do so-

Hope this helps!

Thank you @Jaskirat this is very useful. May I take this opportunity to request Mathworks Team to implement also SGP4 in the "Orbit Propagation Block" in the future releases of Simulink ?
