Tactical Narrowband SATCOM -Geosynchronous Coverage

Project Type

Project Replace


The Tactical Narrowband SATCOM – Geosynchronous Coverage (TNS-GEO) will provide Ultra-High Frequency (UHF) narrowband SATCOM, essential for Beyond Line Of Sight communications for tactical operations and highly-mobile platforms. The project initially included Arctic SATCOM capability but this part of the project scope was moved to the Enhanced Satellite Communication Project – Polar (ESCP-P), resulting in the project being renamed to TNS-GEO.


TNS-GEO will provide guaranteed access to low-capacity UHF narrowband SATCOM globally between 65°N and 65°S latitudes. TNS-GEO will deliver both assured space and ground segment access to assure the required SATCOM capacity, the worldwide availability, and maximum flexibility to support CAF operations deployed domestically or internationally.
