In order to performing the joint operation of Korean army efficiently, informations about surveillance, reconnaissance, and situation awareness need to be possessed jointly. In the first development phase (basis type) of the Korean joint tactical data link system (JTDLS-K), essential tactical information and recognized situation are owned among platforms in common by using existing wireless terminals. In the second development phase (completion type) of the JTDLS-K, a JTDLS which can perform network centric warfare (NCW) will be developed in due consideration of technology development of the basis type and common technology maturity degree. This is a joint battlefield system that can show fighting power simultaneous and polysynthetically through providing command and control messages effectively to each platform, which is participating in the joint and combined operations. In this paper, the development of JTDLS-K with a common data processor based on common link integration processing (CLIP) is described. From the test results of the system presented in this paper, it is demonstrated that quadrature phase shift keying (QPSK) signals can be applied to the system.

To prepare for the network centric warfare, Korea Joint Tactical Data Link System(KJTDLS) has been developed by the South Korean military recently and its development is divided into two phases: basic and complete ones. Due to the limited bandwidth and low transmission efficiency of the developing KJTDLS (basic), lots of problems could be occurred when the TDMA protocol in Link-16 is applied. In this paper, a new dynamic TDMA frame structure for KJTDLS(basic) is proposed and the performance of the proposed is evaluated through the implementation of simulation.

미래의 전장환경은 기존의 플랫폼 중심전(PCW: Platform Centric Warfare)에서 센서로부터 들어온 디지털 정보를 타격체계에 곧바로 전달하는 Sensor-to-Shooter 개념의 네트워크 중심전 (NCW: Network Centric Warfare)으로 기본 패러다임이 급속히 바뀌고 있으며 네트워크 중심전 수행 능력의 기반이 되는 전술데이터링크의 중요성이 크게 부각되고 있다. 전술데이터링크는 1960년대부터 개발되기 시작하였으며 정보통신의 발전과 함께 무기체계의 디지털화 및 작전개념의 발전 등으로 다양한 전술데이터링크가 개발되고 있다. 현재 미군은 최신의 전술데이터 링크인 LINK-16을 다양한 무기체계에 탑재하고 있으며 연합작전 및 합동작전을 위한 전술데이터링크를 구축하고 있는 반면 아직 우리군은 각 무기체계별로 일부 선진국의 전술데이터링크를 도입하여 적용하고 있을 뿐 모든 무기체계에 적용 할 수 있는 표준 전술데이터링크 및 한국군 단독으로 작전을 수행하기 위한 전술데이터링크가 학보 되지 않아 미래 네트워크 중심전 수행이 미흡한 실정이다. 본고에서는 네트워크 중심전의 핵심인 전술데이터링크에 대한 전반적인 개념과 선진국의 주요 전술데이터링크에 대해서 알아보고 현재 한국군의 전술데이터링크 구축 현황 및 미래 한국군 전장환경에서 적용할 수 있는 한국형 전술데이터링크에 대해서 알아본다.

The importance of networks is gradually expanding in the battlefield environment. As time goes by, the types of tactical data links used in the Korean JTDLS are increasing, and the military's weapon systems equipped with tactical data link systems are increasing. Thorough quality verification is required to provide stable software to the wider battlefield. This study examines how to prepare an environment in which various simulation tests to verify the stability of the Korean JTDLS project can be conducted as diverse as possible using minimal physical space and Hardware resources. Through this, it is possible to improve the completeness of the project and secure the stability of the program, and it is intended to contribute to securing higher stability and reliability by securing maximum test capabilities in a limited test environment even in Linux based system project of a similar environment.

Modern Warfare is transforming into a Network Centric Warfare(NCW) where surveillance systems, command control systems and strike systems are interconnected with advanced IT technologies to share battlefield situations. The South Korean military is using the various tactical data links(TDL) such as Link-K, Link-16, Link-11 and KVMF depending on each military's battlefield situation. Joint Tactical Data Link System(JTDLS) is a system thar shares tactical information in near-real time between army/navy/air joint forces and additionally establishes Link-22 in Link-K, Link-16 and KVMF. In this paper, we propose the Link-22 system structure, Link-22 message analysis and the interface structure between the tactical data link processor and Link-22 to apply Link-22 to the JTDLS.

The combat systems in Korea navy have been operating some kinds of tactical data link systems such as Link-11, ISDL and JTDLS. Each tactical data link system has the ability to transmit and receive tactical information like track, engagement, weapon information by using unique message of theirs. And each unique message has their own format. But a number of tactical data link system make combat effectiveness worse because their major functions are duplicated unnecessarily. So, many advanced countries are trying to make united data link system. Similarly, the combat systems in Korea navy will operate C4I data link system, and it is combined version current ISDL, KNCCS and JTDLS data link system. In this paper, we consider the development current tactical data link systems in Korea navy. Also, compare the characteristics between I-message used in ISDL and Host-Interface message used in C4I. From these results, we analyze advanced points about C4I data link system.

During the ground operation of Korean army, the voice message is mainly used for exchanging informations related to the surveillance and reconnaissance, command and control, and precision strike. However, in order to the battlefield visualization among fighting powers participating in the ground force operation, automatic situational awareness and variable message format (VMF) for command and control are required. For securing core technologies necessary for the battlefield visualization, message standard and message handler are established through several applied researches. Besides, the VMF for equipping a weapon system is in development. In this paper, a study on the Korean variable message format (KVMF), where interoperability of integrated battle management system (BMS) is guaranteed due to performing joint, ground, and combined operations so that the situation awareness and strike system can be automated in almost real time, is presented. From the modeling and simulation (M&S) results of the message processor, delay time is varied in accordance with the number of nodes in unit platoon network, message length, and generation interval of routine messages. Therefore, it is shown that the system performance can be optimized by establishing proper network protocol for each situation.
