Communication satellite payload architecture simulation tool - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.
