## Why It Matters
Türksat 4B is part of Turkey’s fleet of communications satellites, representing a national asset for telecommunications and broadcasting services from geostationary orbit. Built by Mitsubishi Electric and operated by Türksat, the satellite reflects an international collaboration combining Turkish operational management with Japanese manufacturing and a Russian launch service. Its placement in geostationary orbit enables continuous, fixed-position service coverage relative to the Earth's surface, a critical capability for reliable satellite-based communications. The 2015 launch by a Proton-M with a Briz-M upper stage from Baikonur Cosmodrome underscores the multi-national logistics often needed to place modern geostationary communications satellites on station. As a member of the Türksat constellation, Türksat 4B contributes to Turkey’s infrastructure for telecommunications, broadcasting, and related satellite services, supporting national and regional connectivity needs.
