Terrestar Solutions joins with Equatys, expanding shared satellite infrastructure for global direct-to-device and advanced MSS connectivity while preserving national sovereignty

Viasat, Space42, and Terrestar Solutions signed a memorandum of understanding to build an open, standards-based interoperability framework between Terrestar's planned Canadian LEO constellation CaStar and Equatys, the shared direct-to-device infrastructure platform Viasat co-founded with up to $1 billion in combined equity commitments. This is the first application of Equatys' "sovereign shell" model, in which nationally controlled constellations interwork with the global shared platform while operators retain ownership of their assets and customers.
