C-3 System
Globalstar's planned third-generation network of more than 50 MDA-built satellites to support services over an expanded mobile satellite spectrum network.
Why it matters
C-3 is the planned successor to Globalstar's current network, and Amazon's obligation to close its acquisition of Globalstar depends in part on government approvals tied to it.
How the technology works
Globalstar contracted MDA in February 2025 for more than 50 third-generation satellites at a total price of $775 million. It has acquired operational rights to the related AST-NG-C-3 ITU filing made by France.
