The Pirinçlik sensor system consisted of two radio frequency (RF) mechanical radar systems providing radar intelligence, space surveillance, and missile warning data to multiple users. Observations from Diyarbakır were normally the first radar reports of new Russian satellite launches from Kapustin Yar in the early days of satellite tracking; see Project Space Track. The site operated both a detection radar (AN/FPS-17) and a mechanical tracking radar (AN/FPS-79). Although limited by their mechanical technology, Pirinçlik's two radars gave the advantage of tracking two objects simultaneously in real time. Its location close to the southern Soviet Union made it the only ground sensor capable of tracking actual deorbits of Soviet space hardware. In addition, the Pirinçlik radar was the only 24-hour-per-day eastern hemisphere deep-space sensor.
