Resumo: The error due to the ionosphere in the GPS observables is directly proportonal to the Total Electron Content (TEC) in the ionospheric layer. The TEC varies regularly in time and space in relation to the sunspot number, the season, the local time, the geographic position, and others. However, the TEC can suffer abruptmodifications in its behavior due to the occurrence of intense solar flares. During a solar flare event a fast increase of the solar electromagnetic radiation occurs, especially in the rays X and extreme ultraviolet wavelengths that can provoke a series of phenomena in the ionosphere that are generically called SuddenIonospheric Disturbances (SID). In this paper, GPS data from RBMC and IGS network were used, to analyze the influence of the intense solar flare, occurred on October 28, 2003 on the behavior of TEC and in the performance of the point positioning in the Brazilian region.

O TEC varia regularmente no tempo e no espaço com relação: ao ciclo de manchas solares (variação de longo período), à época do ano (variação sazonal), à hora do dia (variação diurna), à  localização geográfica, entre outros parâmetros. No entanto, o TEC pode sofrer abruptas modificações em seu comportamento devido, por exemplo, à ocorrência de intensas explosões solares (solar flares). Na ocorrência deste evento solar ocorre um rápido aumento do fluxo solar de radiação eletromagnética,  especialmente na faixa dos raios X e extremo ultravioleta, que, se direcionado para a Terra, pode provocar uma série de fenômenos na ionosfera, genericamente chamados de Distúrbios Ionosféricos Súbitos (DIS). Neste artigo foram utilizados dados das estações GPS da RBMC e da rede IGS para analisar a influência da intensa explosão solar, ocorrida em 28 de outubro de 2003, no  comportamento do TEC e na performance do posicionamento por ponto na região brasileira.Boletim de Ciências GeodésicasBulletin of Geodetic Sciences2006-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/bcg/article/view/7234Boletim de Ciências Geodésicas; Vol 12, No 2 (2006)Bulletin of Geodetic Sciences; Vol 12, No 2 (2006)1982-21701413-4853reponame:Boletim de Ciências Geodésicasinstname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/bcg/article/view/7234/5184Matsuoka, Marcelo TomioCamargo, Paulo de OliveiraBatista, Inez Staciariniinfo:eu-repo/semantics/openAccess2007-01-17T16:31:54Zoai:revistas.ufpr.br:article/7234Revistahttps://revistas.ufpr.br/bcgPUBhttps://revistas.ufpr.br/bcg/oaiqdalmolin@ufpr.br|| danielsantos@ufpr.br||qdalmolin@ufpr.br|| danielsantos@ufpr.br1982-21701413-4853opendoar:2007-01-17T16:31:54Boletim de Ciências Geodésicas - Universidade Federal do Paraná (UFPR)false
