As I understand it, the COSPAS-SARSAT MEOSAR packages are only going on Galileo[*] satellites. There were supposed to be thirty Galileo satellites for a full constellation, but Wikipedia tells me there are 22 satellites in orbit and fully operational.

The European Space Agency (ESA) doesn't appear to have any Galileo launches on their calendar. I wasn't able to find any public documents explaining that right away.
