Fiber Optic Reference Frequency Distribution to Remote Beam Waveguide Antennas (2004)
Calhoun, M., Kuhnle, P., Law, J.
In the NASA/JPL Deep Space Network (DSN), radio science experiments (probing outer planet atmospheres, rings, etc.) and very long-base interferometry (VLBI) require ultra-stable, low phase noise...
Fiber Optic Reference Frequency Distribution to Remote Beam Waveguide Antennas (2004)
DSN radio science experiments and VLBI require ultra-stable, low-noise reference frequency signals. Because of their low attenuation, immunity to EMI/RFI, and temperature stability, fiber optic...
