Communication satellite payload architecture simulation tool - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts. Here is the full original RF Cafe Forums on Archive.org

Dear All;

If there exists any tool that will simulate the end-to-end payload achitecture starting with the receiver antenna upto the TX antenna, I would like to know.

Thanks for the info in advance,

Mehmet

I would start with a spreadsheet and work up from there.

Every time I have incorporated a VSAT system into an overall network, the supplier, back in the day it would be Marconi, BTI or Ferranti, had their own software model developed just as rfdave advises: from the block schematic of the satellite transponder transferred to a spreadsheet using the published parameters for each block. For example Rx G/T, min and max drive levels, Tx power output, Tx G/T and so on.

The power of this approach is that you need to study the transponder structure as well as the physical significance of the parameters. That way you get to understand how the system works, and what the answers from the model really mean.

If you go for a quick fix of applying someone else's software without studying what these blocks of the model do, then you can be easily misled.

To understand the answer it is best first to understand the question.
