ASELSAN Details GÖKBAĞI: A Sovereign LEO-Satellite and Military 5G/6G Network

ASELSAN has disclosed details of GÖKBAĞI, a system that fuses a low-Earth-orbit satellite constellation with a military 5G/6G core to deliver secure, uninterrupted battlefield connectivity without dependence on foreign suppliers.

Turkish defence electronics house ASELSAN on 7 July released fresh detail on GÖKBAĞI, a programme that ties a national low-Earth-orbit (LEO) satellite constellation to a military 5G and 6G communications core. The company frames the effort as a way to keep forces connected anywhere on Earth, including areas where terrestrial networks are degraded or absent.

First surfaced at a strategy conference earlier this year, GÖKBAĞI is now presented not as a stand-alone satellite link but as an integrated combat-communications architecture spanning space, ground and network layers under a single prime contractor.

Three layers, one integrator

According to ASELSAN, GÖKBAĞI rests on three pillars: a national LEO constellation whose size has not been disclosed; advanced satellite control centres on the ground; and a military 5G/6G core enabling tactical data sharing. ASELSAN manages all three segments as prime contractor and integrator.

The system promises encrypted communications, high data capacity, on-the-move connectivity and high resilience in electronic-warfare conditions. Because LEO satellites orbit relatively close to the surface, they cut latency, an advantage for real-time command-and-control.

No foreign ‘off-switch’

The core rationale is reduced dependence on external communications infrastructure. In a high-intensity conflict, commercial or allied satellite links may be throttled or cut, making a sovereign orbital backbone a strategic requirement. GÖKBAĞI is designed so that a third party cannot disconnect the armed forces’ network at will.

The concern has sharpened as many militaries recognise the exposure created by reliance on commercial constellations, where an outside actor could decide when and where connectivity ends.

Part of a wider space push

GÖKBAĞI does not stand alone. It sits alongside Türkiye’s GÖKTÜRK observation satellites, the TÜRKSAT-6A communications satellite and several private-sector constellation ventures, reflecting a broader drive to deepen orbital capability.

The programme remains in its contractual and planning phase; constellation size, orbital altitude, budget and deployment timeline have not been released. Even so, GÖKBAĞI aligns closely with the electronic-warfare resilience and sovereign-communications themes now central to Turkey’s defence industry, and could eventually integrate with ASELSAN’s existing family of tactical radios and command systems.
