A variety of economic sectors rely upon the use Global Navigation Satellite Systems (GNSS) in areas such as autonomous navigation, timing, land management, oil exploration, precision agriculture, civil aviation. Spatial and temporal gradients (or irregularities) ionospheric plasma density distribution introduce disturbances on propagation GNSS radio signals. These originate additional errors outages that degrade positioning quality, thus producing an impact GNSS-based applications. The...
Abstract A limitation to the use of Global Navigation Satellite System (GNSS) for precise and real‐time services is introduced by irregularities in ionospheric plasma density. An EISCAT UHF/ESR experiment was conducted characterize effect electron density on temporal fluctuations TEC along directions transverse GPS ray paths high latitudes ionosphere. Two representative case studies are described: Enhancements originating (a) auroral ionosphere following particle precipitation (b) polar...
Irregularities in the spatial distribution of ionospheric electron density introduce temporal fluctuations intensity and phase radio signals received from Global Navigation Satellite Systems (GNSS). The impact originating irregularities auroral polar ionospheres on GPS positioning was investigated three days March 2018 presence quiet-to-moderately disturbed magnetic conditions by combining measurements EISCAT UHF/ESR incoherent scatter radars. Two different solutions were analysed: broadcast...
