Resumo: | Since the creation of the NAVSTAR/GPS several sources of observational errorshave been identified and studied. They include, among others, ionospheric delayand clock offsets. The error caused by multipath, however, persists as a challenge,especially for applications that demand high accuracy. In Brazil, with thepromulgation of Law 10267/2001 creating the National Cadastre of RuralProperties (CNIR), this challenge assumes a specific feature since it influences theapplicability of the new cadastral system. The GPS receiver manufacturingcompanies have been making large investments in research to deal with multipath,especially at receiver design level. This work performs an analysis of the appliedtechnologies involved in the Ashtech Promark 2 GPS receiver in field conditions asrealistic as possible similar to the ones encountered in geodetic surveys satisfyingCNIR’s specifications. The results show the potential of using such receivers tocertification works by the Instituto Nacional de Colonização e Reforma Agrária(INCRA). It also makes evident their limitations. |

O erro causado pelo multicaminho, no entanto, persistecomo um desafio, especialmente para aplicações que exigem maior acurácia. Nocaso do Brasil, com a promulgação da Lei 10267 que institui o Cadastro Nacionalde Imóveis Rurais (CNIR), este desafio passou a ter uma conotação específica, poisinfluencia a aplicabilidade do novo sistema cadastral. As empresas fabricantes dereceptores GPS tem feito grandes investimentos em pesquisa em nível de projetodos seus receptores. A presente pesquisa busca estudar as tecnologias aplicadas noreceptores GPS Ashtech Promark2, bem como analisar o desempenho dessastecnologias em condições de campo de extrema dificuldade para o rastreio do sinalprovocadas por cobertura vegetal, como é comum em georreferenciamento para oCNIR. Os resultados mostram grande potencial de uso desse receptor para trabalhosde certificação junto ao INCRA, bem como evidenciam situações limites em que oemprego do mesmo fica prejudicado.Boletim de Ciências GeodésicasBulletin of Geodetic Sciences2007-07-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/bcg/article/view/8253Boletim de Ciências Geodésicas; Vol 13, No 1 (2007)Bulletin of Geodetic Sciences; Vol 13, No 1 (2007)1982-21701413-4853reponame:Boletim de Ciências Geodésicasinstname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/bcg/article/view/8253/5772Farret, Julio Cesardos Santos, Marcelo CarvalhoSaatkamp, Eno DarciPalma, Evandroinfo:eu-repo/semantics/openAccess2007-07-03T21:08:57Zoai:revistas.ufpr.br:article/8253Revistahttps://revistas.ufpr.br/bcgPUBhttps://revistas.ufpr.br/bcg/oaiqdalmolin@ufpr.br|| danielsantos@ufpr.br||qdalmolin@ufpr.br|| danielsantos@ufpr.br1982-21701413-4853opendoar:2007-07-03T21:08:57Boletim de Ciências Geodésicas - Universidade Federal do Paraná (UFPR)false |
