ABSTRACT: The primary objective of this proposal is to demonstrate the feasibility of producing a sub-millisecond internal LAN time synchronization (SILTS) capability which does not require the use of external time references. It is also highly desired that the SILTS not require custom components such as hardware and drivers. The proposed SILTS solution will provide a reliable non-intrusive time synchronization system at the application program interface by employing a customized precision time protocol over a LAN. A secondary objective of this proposal is to demonstrate the feasibility of producing a network node capable of producing IRIG B (Inter Range Instrumentation Group) synchronization signals for distribution to legacy components. BENEFIT: There is a critical need for the ability to precisely synchronize data acquisition computers on a LAN for time stamping and controlling events. Typically computers are synchronized using external hardware such as GPS and IRIG B cards. These implantations are undesirable since they require long cables and external hardware which increases complexity and implementation/maintenance costs. A stand alone solution that doesn"t required the use of such hardware would be invaluable to the Air Forces data acquisition and test groups. There are many applications for such a system in commercial sectors such as industrial automation and control systems requiring precise control of timing and data acquisition.
