The Research Of Timer Simulation System Of Tactical Data Link

Information is the key factor of the modern warfare. The data link is vital equipment, which can gain the information superiority, raise the reaction ability of the units in the war, and realize the automation of fighting command. The data link exchanges and distributes the data information among units in the war through wireless channel, and deals with the various information using the amalgamation technology.In this paper, firstly the development of internal and abroad data link is followed, and its huge effect in the modern wars is analyzed. It can provide the various operation information of real time and near real time for the commander on the basis of enjoying the information resource altogether. Secondly, expounds Link-16 system. JTIDS is a synthetic tactic communication system which integrates communication, navigation, identification, introduces its basic working mode, communication technique, terminal device, system features.JTIDS timer system; mainly discuss the network time delaying effection of JTIDS simulation system.The major research content of this paper is introducing the simulation of JTIDS terminal take responsibility for sending and receiving information in real time, that the timer system is the foundation, and then discusses the measurement of simulative system's network delay, propose a terminal timer adjust algorithm based on VxWorks RTOS, then analyzing of error.
