How to create NTN Ray Tracing Simulation?

[aaronbuck02]

Is there any way to only compute the CIR with certain AOA values, either through controllable AOA or filtering of path AOAs? We are trying to simulate fast fading of satellite to ground communication link since putting the transmitter far away(at LEO) doesn't produce sufficient path density resulting in an inauthentic CIR. Therefore, we want to move the transmitter closer, while replicating AOA distribution for the LEO case.

have you checked OpenNTN library?

Hello, Im trying to do coverage extension for RIS in NTN communications and was wondering how to put a RIS (I can do that in Sionna RT 0.19.2) with a satellite. I know you can do that as a transmitter placing it very far away but that won't be exactly accurate so was wondering if there was any way to actually integrate both Sionna RT with the RIS and the satellite model from OpenNTN or if you had any insight to how I could do both. Thanks in advance!
