What is CTech? Turkish Aerospace’s satellite comms arm
Quick answer: C Tech Bilisim Teknolojileri Sanayi ve Ticaret A.S. (CTech) is a Turkish defence communications company founded in Istanbul in 2005 and a subsidiary of Turkish Aerospace (TUSAS) since 2018. The company develops satellite communication (SATCOM) terminals, jam-resistant modems, line-of-sight (LOS) data links, aviation flight recorders and space-qualified satellite equipment. Dr. Cuneyd Firat serves as General Manager and Dr. Ozkan Altay chairs the Board of Directors. CTech products have logged more than 500,000 flight hours on the ANKA and AKSUNGUR unmanned aircraft, and the company built core elements of the telemetry and telecommand subsystem of the TURKSAT 6A communications satellite.
When and how was CTech founded?
According to the company’s official history page, CTech was established in Istanbul in 2005. Development of the SecureARX EPM modem began in 2006, and a cooperation with Mitsubishi Electric opened the door to space projects in 2008. An Ankara office followed in 2012. The year 2014 proved a turning point: CTech was selected as the Turkish Armed Forces’ EPM modem supplier with SecureARX and joined the TURKSAT 6A programme. The company became a Turkish Aerospace subsidiary in 2018 and marked its 20th anniversary in February 2025.
Which product areas does CTech cover?
The official catalogue is organised around four main axes: satellite communications, line-of-sight communications, aviation equipment and space systems. The SkyARX satellite communication terminal gives airborne platforms broadband connectivity, the SecureARX EPM modem is being supplied to NATO’s protected satellite communication infrastructure, and the UfukLink data links carry real-time mission data between air and ground.
