As I understand it, Signal is software. It requires an Operating System capable of running it to use it such as IOS, Android, Windows, Linux.
A "Sat Phone" could be describing any device that can communicte to satellites directly. I haven't kept up on tech in this realm as much as others but I don't think there are any satellite phones that have the required specifications to run Signal. They will allow the user to only send and recieve voice and texts and send SOS signals for emergencies.
Now, much like the mobile world there are "hot spots terminals" that a user can purchase for the satellite connectivity which would enable the user to use their normal cell phone or any internet device for that matter and esentially use the internet at a fairly low bit rate.
Lastly, I'm not sure if the Signal App needs to connect to a home service or a cloud service in order to funcion. If it does and the internet is out globally then the Signal App service might not work even if you can utilize a direct satellite connection to whatever state the "internet" is in at that point.
TL;DR In a round about way yes a user can use the Signal App over a satellite connection. The caveat is at a large expense for the equipment and subsequent service fees.
