I looked at the Wiki, I still have some questions still.
Can my Uniden BCD436HP monitor SATCOM out of the box or do I need additional software?
What voice format is used on this band?
Is there digital voice, or all analog?
What is the range on the SATCOM, or is this a global coverage with no defined limits?
Lastly, do I need to monitor both the up and down frequencies to follow the conversations?

Any other pertinent information I need that I haven't asked yet?

Don't want to get to plugging these frequencies in and miss out on most of what's going on.
