Abstract :
Round Trip Timing (RTT) and PPLI message are two ways of time synchronization in the Joint Tactical Information Distribution System (JTIDS) network. The former is a kind of active time synchronization, which could make the user have high timing level directly. The latter is completely passive and could provide low level time synchronization as a byproduct of navigation. This paper begins with the introduction of the two timing mechanisms of JTIDS network. Models of passive and active time synchronization are built up respectively. Two filters, one is navigation filter and the other is RTT filter, are designed based on the models. Simulation validates the design of the two filters, and effects of major error sources and model uncertainty are analyzed
