Web1 mrt. 2010 · 2.1.2. Mapping Function. Precision monitoring of ionosphere will have profound implications in almost all areas of GPS user communities. The ionospheric mapping function is one of the first assumptions to consider typically when ionospheric corrections are estimated or applied from Global Navigation Satellite System (GNSS) data. WebCharacteristic concentrations of dust particles in the meteoroid tails during flashes as a function of altitude are estimated. Using the example of modulational instability of electromagnetic waves related to the dust-acoustic mode, we demonstrate how increased concentration of dust particles during flashes influences the growth rate of the instability … gary lineker david attenborough
