O GLONASS (GLObal NAvigation Satellite System) e o GPS (Global Positioning System) são os sistemas pioneiros de navegação global por satélite. A utilização combinada de dados GPS e GLONASS despertou interesse inicialmente, mas as pesquisas com

Quando se almeja maior acurácia no posicionamento GNSS, é imprescindível a correção dos efeitos de ordem superior da refração ionosférica. O erro associado à ionosfera é diretamente proporcional ao conteúdo total de elétrons (Total Electr

Existing climatological ionosphere models, for example, GISM, SCIONAV, WBMOD, and STIPEE, have known limitations that prevent their wide use. In the framework of ESA study “Radio Climatology Models of the Ionosphere: Status and Way Forward” their

Atualmente, a interferência da camada ionosférica nos sinais da banda L, transmitidos pelos satélites GNSS (Sistema Global de Posicionamento por Satélite), é a maior fonte de erro na utilização deste sistema. Durante a sua propagação entre a

Značajan korak u povijesti pozicioniranja i navigacije započeo je s razvojem globalnih navigacijskih satelitskih sustava. Od prvobitne ideje o isključivo vojnoj primjeni do današnje dominantno civilne upotrebe. Implementacijom ovog sustava na bro

Signal koji je odaslan s GPS satelita ka njegovom korisniku, podložan je utjecaju ionosfere stvarajući tako njegovo kašnjenje. To kašnjenje signala naziva se ionosfersko kašnjenje te kao rezultat daje odstupanje položaja korisnika. Ionosfersko

Sunce konstantno emitira radijaciju i ionizirane čestice putem solarnog vjetra, a može doći i do naglog povećanja emisije tijekom fenomena kao što su solarna baklja i koronalni izbačaji mase. Sunčeva aktivnost prati 11-godišnji ciklus te je u
