Development and Validation of a Limb-to-Disk Algorithm for Mapping Radio Occultation Measurements of Scintillation to the Vertical Propagation Geometry

Charles S. Carrano, K. M. Groves, William J. McNeil, E. Yizengaw et autres

Modern radio occultation (RO) receivers can routinely provide high-rate observations during ionospheric scintillation events. The high-rate data enables direct measurement of the amplitude and phase scintillation indices (S4 and sigma-phi) as well as indirect (model-inferred) estimation of turbulence strength integrated along horizontal …

Processing and Validation of FORMOSAT‐7/COSMIC‐2 GLONASS Total Electron Content Observations

N. M. Pedatella, Irina Zakharenkova, John Braun, Iurii Cherniak et autres

Abstract The Formosa Satellite‐7/Constellation Observing System for Meteorology, Ionosphere, and Climate‐2 (FORMOSAT‐7/COSMIC‐2, F7/C2) Tri‐GNSS Radio Occultation System observes both Global Positioning System (GPS) and GLObalnaya NAvigazionnaya Sputnikovaya Sistema (GLONASS) slant total electron content (TEC). Space‐based TEC observations have historically relied on GPS …

Processing and Validation of FORMOSAT‐7/COSMIC‐2 GPS Total Electron Content Observations

N. M. Pedatella, Irina Zakharenkova, John Braun, Iurii Cherniak et autres

Abstract Slant absolute total electron content (TEC) is observed by the Formosa Satellite‐7/Constellation Observing System for Meteorology, Ionosphere, and Climate‐2 (FORMOSAT‐7/COSMIC‐2, F7/C2) Tri‐GNSS Radio Occultation System (TGRS) instrument. We present details of the data processing algorithms, validation, and error assessment for the …

Detection and Localization of Terrestrial L Band RFI with GNSS Receivers

Max Roberts, T. K. Meehan, P. R. Straus, Jeffery Y. Tien et autres

GNSS signals are critically important for a wide range of commercial, military, and science applications. Recent studies have identified threats to the performance of GNSS from both intended and unintended sources of radio frequency interference (RFI). Understanding the distribution of the sources …
