What's the future for Sat Coms


I'm new to all of this,and that's why I ask? I see yawl are using HT and manually pointing antennas to the Sat, after locating them by soft ware,and working Dx.If I have the above right? Can you use the Sat for emergencies, ( I'm at sea and my boat is sinking, Help!! )?, can you Receive info from other SAT using FM or SSB, like WX? what would a table top rig like The ten-tec 526 work?
