CTech

C Tech Bilişim Teknolojileri A.Ş. (CTech) develops satellite and line-of-sight communication technologies for defense and aerospace. Founded in Istanbul in 2005, it has been a subsidiary of Turkish Aerospace (TUSAŞ) since 2018. Its headquarters and production are at Teknopark İstanbul in Pendik, with an office at Bilkent Cyberpark in Ankara; it reports more than 250 employees and 4,500 m² of production and engineering space.

CTech builds communication systems for air, land, sea and space platforms. Its products have passed 500,000 flight hours on the ANKA and AKSUNGUR unmanned aircraft and flew in space on Türksat 6A. In 2020 it began delivering SATCOM on-the-move terminals for drones under a programme of Turkey's Defence Industries Presidency. Recent work includes a hybrid communication concept for swarms of unmanned surface vessels and secure communications tested at NATO's CWIX 2026 exercise.

CTech sells to defense ministries, armed forces and platform manufacturers rather than to businesses looking for an internet subscription.
