Refinement Filter Analysis & Design Report: Application of Differential GPS Processing to Precision Link-16 Navigation and Synchronization

Abstract

An innovative algorithm has been developed and evaluated which utilizes Differential GPS techniques to enhance Link 16 navigation and time synchronization performance. Relative positioning accuracies within a mobile airborne community on the order of one foot, and time synchronization to less then one nanosecond have been demonstrated. The algorithm is structured as an Extended Kalman Filter mostly these position errors, clock bias, and frequency drift. Plans are described for laboratory demonstration using Link-l6 terminals by Spring 2004.
