Data for manuscript entitled "Compact dual comb time-transfer and ranging for future space-based distributed sensing"

Metadata Updated: July 9, 2025

Data for the figures in the manuscript entitled "Compact dual comb time-transfer and ranging for future space-based distributed sensing" published in Applied Optics. Abstract: We describe a general design for a compact frequency comb-based optical time transfer and ranging node with volume of 14 L, mass of 10 kg, and power consumption of 46 W. We assess the residual noise from the comb-based system by making both ranging and time transfer measurements using these compact nodes over a 4.4 km free-space testbed. We demonstrate that this node design has the potential to support sub-femtosecond clock comparisons and sub-micron range measurements at averaging intervals of one second with a mean received power of 20 nW. This is more than sufficient to support future space-based distributed coherent sensing at observing frequencies beyond 1 THz. Fig4a: Time-of-flight measurements from node 1 and node 2. Fig 4b: The difference in measured time of flight between nodes.Fig5: Clock offset measurements between node 1 and 2 based on the 1 m fiber reference arm and 4.4 km link time offset data. Fig6: Timing jitter PSD for one-way time-of-flight, clock offsets, and time-of-flight difference measurements. Fig7: Time deviation for time-of-flight difference and clock offset measurements.
