Abstract

There is a strong desire to improve the ability to determine the relative position of a network of vehicles (such as aircraft, tanks, troops, etc). This research uses two-way time-transfer (TWTT) measurements, which are already being used for precise relative time measurements, to improve relative positioning of a vehicle network. This research characterizes the impact of using TWTT measurements to improve positioning of vehicle networks. The results show that including TWTT measurements in particular scenarios can reduce the 3-dimensional positioning errors by 11-42% and reduce the relative clock errors from 15% to over 99%
