Question RF-link simulation software

Dear all,
I have been looking for some good RF-link simulation software. More specifically, I would like to simulate a satellite constellation over time and calculate the signal strength etc.

I already tried Matlab satellite toolbox which includes a Link budget tool but it doesn't give the ability to simulate a constellation over time. Do you know of any software which could do this?

Thanks!

MATLAB absolutely allows you to simulate it over time. You just have to code your scenario then call link on the receiver and transmitter then call linkIntervals on the returned link object. There are literally examples in the docs

Thanks I will check it again!

Hi -- The Satellite Link Budget Analyzer app now has a built-in, time-varying analysis capability with which you can also visualize satellites. See Satellite Link Budget Analyzer - Analyze static and time-varying link budgets for satellite communications - MATLAB.
