In this paper, design measure were proposed for the construction of terminal systems for airborne platforms, which are key element in the Joint Tactical Data Link System (JTDLS) complete system. The Korean perfect tactical data link (JTDLS) is a communication system to establish an independent tactical data link network and needs to develop a MIDS-LVT (Link-16) communication terminal for datalink. Once a Ground/Navy JTDLS terminal system is established around airborne platform, it will be possible to break away from reliance on NATO-based tactical data link joint operations and establish independent Korean surveillance reconnaissance real-time data sharing and tactical data link operations concepts. in this paper, the essential development elements of airborne platform mounting and operable JTDLS terminals are presented, and the concept of system design is proposed to embody them. Further, improved system performance was analyzed by applying the concepts of complex relative navigation system and Advanced TDMA protocol for the deployment of airborne tactical datalink networks.

Korea Department of Defense has been developing Link-K, Korean Joint Tactical Datalink, to support their independent joint operations and trying to enlarge the scope of Link-K tactical message delivery to nodes in IP based tactical networks for sharing situation awareness more broadly. A Link-K tactical message size is too small to fit into an IP packet, inefficiently wasting most of the IP packet space of the low bandwidth IP-based tactical networks. This paper proposes a new Link-K tactical message aggregation and delivery method when tactical messages need to be sent to some nodes located at IP-based tactical networks. With numerical analysis and OPNET simulation studies, we prove the effectiveness and efficiency of the proposed method.

In this paper, we propose how to efficiently apply IP and TDL(Tactical Datalink) protocol to the Link-K network for using their applications on the host system. We classify 3 kinds of communication method between IP network and TDL network. We explain the concepts of Like-to-Like communication (Link-K over IP, IP over Link-K) and Any-to-Any communication. We describe the characteristics and the implementation range of tactical datalink processor for each communication method.

In modern warfare, the main factor of triumph is superior situation awareness which leads rapid command decision and precisely guided munition, and TDL(Tactical Data Link) is the main communicational enabler. ROK forces currently operate Link-16 with allied forces and are also developing Korean national data link, Link-K which is also planned to be cooperated with Link-16. Assigning participant and track numbers needs agreement between ROK and allied forces, but ROK forces have exclusive authority in assigning numbers in Link-K. This paper proposes the effective method of exchange participant and track numbers between Link-16 and Link-K, and applicability verification in operational test and evaluation will be also presented.

In this paper, an extend kalman filter based relative navigation algorithm is proposed for Link-K based relative navigation. Link-K is a tactical data link system for joint operation capability upgrade of ROK forces. Link-K is inter-operable with Link-16 and transmit and received information of operations and target. In Link-K communication channel, PPLI message including transmitter position and TOA measurement can be used for relative navigation. Therefore Link-K based relative navigation system can be operated. In this paper, software based simulations were carried out for operational feasibility test and performance verification as error factors of proposed Link-K based relative navigation system.
