Influence of different types of ionospheric disturbances on GPS signals at polar latitudes [PDF]
Annales Geophysicae, 2021 The comparative research of the influence of different types of auroral particle precipitation and polar cap patches (PCPs) on the global positioning system (GPS) signals disturbances in the polar ionosphere was done.

Polar cap patch transportation beyond the classic scenario [PDF]
Journal of Geophysical Research: Space Physics, 2016 AbstractWe report the continuous monitoring of a polar cap patch, encompassing its creation, and a subsequent evolution that differs from the classic behavior. The patch was formed from the storm‐enhanced density plume, by segmentation associated with a subauroral polarization stream generated by a substorm.

Two‐Dimensional Reconstruction of Ionospheric Plasma Density Variations Using Swarm
Space Weather, 2020 Space weather phenomena such as scintillations of Global Navigation Satellite Systems (GNSS) signals are of increasing importance for aviation, the maritime, and civil engineering industries.

Journal of Space Weather and Space Climate, 2014 We directly compare the relative GPS scintillation levels associated with regions of enhanced plasma irregularities called auroral arcs, polar cap patches, and auroral blobs that frequently occur in the polar ionosphere.

Polar cap patches, GPS TEC variations, and atmospheric gravity waves [PDF]
, 2021 <p>The southward pointing field of view of the Canadian component of the Resolute Bay Incoherent Scatter Radar (RISR-C) is well suited for observing the ionospheric signatures of flux transfer events and subsequent polar patch formation in the cusp.

ESR mapping of polar‐cap patches in the dark cusp [PDF]
Geophysical Research Letters, 2002 We present the first ever measurement of the full thermal plasma properties, of an ionospheric patch in full darkness in the noon region where patches are believed to form. Further these data present the first experimental evidence for the Lockwood and Carlson class of mechanisms for forming patches by plasma injection.

Relationship of theoretical patch climatology to polar cap patch observations
Radio Science, 1996 During a southward orientation of the interplanetary magnetic field (IMF), patches are often observed moving antisunward across the polar cap. In saying “patches” we refer to structures in which the F region electron densities are enhanced relative to lower background levels; we do not in this paper consider patches which are observed optically (see J.

Direct observations of the full Dungey convection cycle in the polar ionosphere for southward interplanetary magnetic field conditions [PDF]
, 2015 Tracking the formation and full evolution of polar cap ionization patches in the polar ionosphere, we directly observe the full Dungey convection cycle for southward interplanetary magnetic field (IMF) conditions.

GPS TEC, scintillation and cycle slips observed at high latitudes during solar minimum [PDF]
Annales Geophysicae, 2010 High-latitude irregularities can impair the operation of GPS-based devices by causing fluctuations of GPS signal amplitude and phase, also known as scintillation.
