NIST s role in providing the optical radiation measurement science and standards to ensure the quality, accuracy, and comparability of our Nation s remote

Effects of the Rooftop Environment on GPS Time Transfer

Author(s)
Michael A. Lombardi, Andrew N. Novick
We examine the effects of the rooftop environment on GPS time transfer, in particular the effects of multipath reflections from nearby metallic objects. Three

Long-term Stability of NIST Chip-Scale Atomic Clock Physics Packages

Author(s)
Svenja A. Knappe, V Shah, Vladislav Gerginov, Alan Brannon, Leo W. Hollberg, John E. Kitching
We present measurements regarding the long-term frequency instability of NIST CSAC physics packages. Changes of the clock frequency are caused mainly through
