Roketsan Star Tracking Navigation System Studies
Roketsan Advanced Technology and Systems (ITS) Assistant General Manager Advanced Technologies Directorate has produced the only system among the star-following navigation systems developed in Turkey, which can operate in dynamic conditions such as vibration and high rotational speed, as a result of the star-following navigation system development studies started in 2017.
Star Tracking Navigation Systems (YTNS)
Star Tracking Navigation Systems (YTNS) are navigation systems that generate highly accurate orientation information. With the optical components and detectors they have, YTNS detects the stars in the images they take, compares the positions of the stars with respect to each other with the positions on the known star maps, and creates sensitive orientation information with sub-degree accuracy.

Details about the project were shared in the article, Star Tracking Navigation Systems, written by Roketsan engineers Selva Sargın Güçlü, Aslı Doğan and Mehmet Akif Koca in the January 2020 issue of Roketsan Magazine.
Roketsan continues the verification studies of the system, for which optical, mechanical and algorithm design has been made within the scope of the project. With the completion of the verification work, a precision orientation system with <60 arc seconds angle accuracy, <6 kg in weight, and generating the first orientation information in less than 10 seconds will be included in the navigation system.
Roketsan supplied and tested more than one detector within the scope of the study. Alternative algorithm design studies were carried out in the phases of star center determination, star matching and orientation determination in order to develop YTNS suitable for use in dynamic platforms simultaneously with optical design studies.
After the design studies, the optical elements that were produced were assembled, the software containing the algorithm and star maps were embedded in the electronic card and night tests were started.
While the specified YTNS design and testing processes were continuing, integration studies were carried out with the ANS and KKS receiver as a component of the navigation system of the targeted product. With this study, it was possible to observe the effect of the platform on which YTNS will be installed, in the modeling simulation environment.
Roketsan's Star Tracking Navigation System solution; It is the only system among star-following navigation systems developed in Turkey that can operate in dynamic conditions such as vibration and high rotation speed. YTNS is planned to be used in various projects in the future.
Roketsan, 2017’de başladığı yıldız takipli navigasyon sistemi geliştirme çalışmaları sonucunda çok önemli ilerlemeler kaydetti.
