Abstract:	The use of dual pseudo-random noise (DPN) signals for two-way satellite time and frequency transfer (TWSTFT) improves the time transfer precision such that it is approximately one order of magnitude better than that of conventional TWSTFT. The interference between the transmission signals must be considered to further improve the time transfer precision because the DPN signal uses very narrow-band pseudo-random noise (PRN) codes. We investigated the interference noise between the transmission signals, and propose an alternative signal scheme to reduce the interference noise.
