Autor: Walter Gekelman, Bertrand Lefebvre, Li-Jen Chen, Jolene S. Pickett, Stephen Vincena, Paul M. Kintner, Patrick Pribyl

Publikováno v: Nonlinear Processes in Geophysics, Vol 18, Iss 1, Pp 41-47 (2011)

Solitary electrostatic pulses have been observed in numerous places of the magnetosphere such as the vicinity of reconnection current sheets, shocks or auroral current systems, and are often thought to be generated by energetic electron beams. We pre

Data-Driven Testbed for Evaluating GPS Carrier Tracking Loops in Ionospheric Scintillation

Autor: Paul M. Kintner, Mark L. Psiaki, Todd E. Humphreys, Alessandro P. Cerruti, Brent M. Ledvina

Publikováno v: IEEE Transactions on Aerospace and Electronic Systems. 46:1609-1623

A large set of equatorial ionospheric scintillation data has been compiled, used to characterize features of severe scintillation that impact Global Positioning System phase tracking, and used to develop a scintillation testbed for evaluating trackin

Modeling the Effects of Ionospheric Scintillation on GPS Carrier Phase Tracking

Autor: Todd E. Humphreys, Paul M. Kintner, Mark L. Psiaki

Publikováno v: IEEE Transactions on Aerospace and Electronic Systems. 46:1624-1637

A characterization is given for the behavior of Global Positioning System phase tracking loops in the presence of severe equatorial ionospheric scintillation. The purpose of this work is to develop a simple, general, and realistic scintillation effec

Simulating Ionosphere-Induced Scintillation for Testing GPS Receiver Phase Tracking Loops

Autor: Todd E. Humphreys, Paul M. Kintner, Joanna C. Hinks, Brady W. O'Hanlon, Mark L. Psiaki

Publikováno v: IEEE Journal of Selected Topics in Signal Processing. 3:707-715

A simple model is proposed for simulating equatorial transionospheric radio wave scintillation. The model can be used to test Global Positioning System phase tracking loops for scintillation robustness because it captures the scintillation properties

PFISR and ROPA observations of pulsating aurora

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 71(6-7):708-716

Previous observations have shown that pulsating aurora sometimes occurs with patches of a vertical extent that is thinner than would be expected for aurora caused by collisional processes, implying that local ionospheric processes are important in ca

GPS L-band scintillations and ionospheric irregularity zonal drifts inferred at equatorial and low-latitude regions

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 70:1261-1272

The main scientific objective of this research is to study the spatial variability and dynamics of the F-region irregularities. To achieve this, amplitude scintillations at the L-band, total electron content (TEC) and irregularity drifts were measure

The SIERRA nightside auroral sounding rocket made observations of the origins of ion upflow, at topside F-region altitudes (below 700 km), comparatively large topside plasma densities (above 20 000/cc), and low energies (10 eV). Upflowing ions with b

Mapping and Survey of Plasma Bubbles over Brazilian Territory

Autor: E. R. de Paula, L. F. C. de Rezende, I. J. Kantor, Paul M. Kintner

Publikováno v: Journal of Navigation. 60:69-81

Ionospheric plasma irregularities or bubbles, that are regions with depleted density, are generated at the magnetic equator after sunset due to plasma instabilities, and as they move upward they map along the magnetic field lines to low latitudes. To

An all-sky imager was installed in Asmara, Eritrea (15.4° N, 38.9° E, 7° N dip) and used to monitor the OI 630-nm nightglow. Nine months of data were studied between September 2001 and May 2002, a time including the recent maximum in the solar act
