OKIS was developed and tested for the first time in the Bayraktar TB2 UAV System which was developed and manufactured uniquely by Baykar.  The Bayraktar TB2 UAV System has been utilized operationally for 3 years by the Turkish Armed Forces.  The automatic take-off and landing system provides precise positioning data to the landing and take-off systems of unmanned air vehicles, by using radar technology.  During the execution of the tests, communication between the OKIS Air Unit integrated to Bayraktar TB2 and the OKIS Ground Unit positioned at the side of the runway was achieved from a distance of 12 km. It was observed throughout the ground and air tests conducted with Bayraktar TB2 and OKIS that the position data generated was highly precise and this would enable automatic landing and take-off capacities to the platform independent from the global positioning system (GPS, Glonass, etc.)

OKIS is used for the redundant and secure take-off and landing for UAVs and is composed of two main units: the OKIS Air Unit containing the transponder and antenna over the UAVs and the OKIS Ground Unit including the mono-pulse radar positioned on the runway. Due to its small size and light weight, OKIS Air Unit can be utilized by almost all types of UAV systems without any significant impact on disposable load capacity.
