Re: Re: [amsat-bb] Amateur radio module on commercial Geo Sat?

The ORBCOMM constellation of 35 LEOs uses DSP chips in the receivers, 
transmitters and modems.

Yes, there are radiation issues that one must be conscious of when 
designing, but that's the case with any components operating in 
space.  In the end, yes, DSP does work in space.

I suspect you would find similar usage in most all commercial 
communciaitons satellites these days.
