Real-Time Two-Way Time Transfer to Aircraft

Abstract : Two-way time transfer (TWTT) has proven itself as an accurate and reliable method for synchronization over large static baselines. While previous demonstrations have shown the merit of extending TWTT to dynamic platforms, the technology has always been dogged by the fact that it requires specialized equipment and post-processing of the data. If TWTT is to establish itself as a viable means of synchronization between dynamic platforms, it must first demonstrate the ability to operate in real-time with COTS hardware. The most recent airborne test set out to demonstrate this capability and the results of that test are presented herein.
