Satellite-based system with better coverage than SPOT, with no annual fee or subscription. Most are good for 4-5 years then must be returned to mfg for battery servicing. They are designed to only be activated in an emergency situation and any activation beyond the built-in test routines requires that the unit be mfgr-serviced.
There are quite a number of people who carry SPOT or InReach for normal tracking and a PLB for when things really go pie-shaped.
Best,
