O posicionamento relativo estático é uma das práticas oferecidas pelo sistema
global de navegação por satélite e permite determinar qualquer posição no globo
terrestre. Este trabalho tem como objetivo determinar coordenadas elipsoidais
de marcos geodésicos no município de Dois Vizinhos – Paraná, Brasil, para
serem disponibilizados como marcos de apoio a trabalhos científicos e
profissionais na região. Para isto, foi definido como marco de referência para os
demais pontos determinados o marco homologado pelo IBGE, denominado
estação 96153. Além deste, foram utilizadas as estações de referência da Rede
Brasileira do Monitoramento Contínuo (RBMC). Os marcos dos quais se
determinaram as coordenadas estão localizados na Universidade Tecnológica
Federal do Paraná (UTFPR), sendo eles UTFPR 01 e UTFPR 02. Outro marco
está localizado na área urbana do município, na Unidade de Pronto Atendimento
(UPA), no bairro Sagrada Família. Conforme os critérios estabelecidos pelo
IBGE, utilizou-se a técnica de posicionamento relativo estático, onde o receptor
de referência e o ponto de interesse permaneceram parados rastreando
simultaneamente por no mínimo 6 horas, em quatro sessões. Os
processamentos dos dados foram realizados em relação às estações
pertencendo à RBMC de Guarapuava (PRGU), Foz do Iguaçu (ITAI), Maringá
(PRMA) e Chapecó (SCCH). Não se utilizou a estação 96153 para o
processamento dos marcos, UTFPR01 e UTFPR02 por apresentar-se como uma
estação de referência muito comprometida devido a suas obstruções ao redor
do marco, indicando um erro superior quando comparado aos resultados obtidos
pela RBMC. Para o processamento e ajustamento dos dados de campo utilizou-
se o software Trimble Business Center. O resultado comparativo do marco UPA
quando processado em relação às bases RBMC e à estação 96153, resultou em
uma discrepância de posicionamento de ΔN= ± 0,075 m, ΔE = ± 0,242 m e ΔH =
± 0,857 m. Considerando que a linha de base entre a estação 96153 e o marco
UPA apresenta uma linha de base curta, cerca de 1,5 km. No entanto, a situação
de obstrução do marco de referência 96153resultou em erros superiores ao
desvio-padrão permitido pela norma. Enquanto a linha de base entre o marco UPA e as estações RBMC consideradas longas, ou seja, superior a 100km,
resultou em erros mínimos comparados ao padrão normatizado pela legislação
brasileira para este tipo de posicionamento. Conclui-se, que as coordenadas
plano-cartesianas sistema UTM, fuso 22 S, SIRGAS 2000 de cada marco,
são:UTFPR01 N 7155400,163m E 289451,357m e H 554,600m; UTFPR02 N
7155427,670m E 289435,482m e H 556,526m; UPA N 7149515,330m E
292797,631m e H 489,073m e a estação 96153 N 7150414,756m E
294021,679m e H 511,542m. Foi realizado uma comparação entre os resultados
da estação 96153 do trabalho com o relatório da estação geodésica do IBGE,
onde observou-se uma discrepância alta, principalmente no valor da altitude (ΔH
= ± 2,758 m).
The static relative positioning is one of the practices offered by the global navigation satellite system and allows to determine any position on the terrestrial globe. This work aims to determine ellipsoidal coordinates of geodetic landmarks in the municipality of Dois Vizinhos – Paraná, Brazil, to be made available as support landmarks for scientific and professional work in the region. For this, the landmark approved by the IBGE, called station 96153 was defined as a reference mark for the other points determined. In addition, reference stations of the Brazilian Network for Continuous Monitoring (RBMC) were used. The landmarks from which the coordinates were determined are located at the Federal Technological University of Paraná (UTFPR), which are UTFPR 01 and UTFPR 02. Another landmark is located in the urban area of the municipality, in the Emergency Care Unit (UPA), in the Sagrada neighborhood Family. According to the criteria established by the IBGE, the static relative positioning technique was used, where the reference receiver and the point of interest remained stationary tracking simultaneously for at least 6 hours, in four sessions. Data processing was carried out in relation to the stations belonging to the RBMC of Guarapuava (PRGU), Foz do Iguaçu (ITAI), Maringá (PRMA) and Chapecó (SCCH). Station 96153 was not used for processing the landmarks, UTFPR01 and UTFPR02 because it is a very compromised reference station due to its obstructions around the landmark, indicating a higher error when compared to the results obtained by the RBMC. For the processing and adjustment of field data, the Trimble Business Center software was used. The comparative result of the UPA landmark when processed in relation to the RBMC bases and station 96153, resulted in a positioning discrepancy of ΔN= ± 0.075 m, ΔE = ± 0.242 m and ΔH = ± 0.857 m. Whereas the baseline between station 96153 and the UPA landmark has a short baseline, about 1.5 km. However, the obstruction situation of benchmark 96153 resulted in errors greater than the standard deviation allowed by the norm. While the baseline between the UPA landmark and the RBMC stations considered long, that is, greater than 100km, resulted in minimal errors compared to the standard established by Brazilian legislation for this type of positioning. It is concluded that the UTM plane-Cartesian coordinates, spindle 22 S, SIRGAS 2000 of each landmark are: UTFPR01 N 7155400.163m E 289451.357m and H 554.600m; UTFPR02 N 7155427.670m E 289435,482m and H 556.526m; UPA N 7149515.330m E 292797.631m and H 489.073m and station 96153 N 7150414.756m E 294021.679m and H 511.542m. A comparison was made between the results of the 96153 work station with the IBGE geodetic station report, where a high discrepancy was observed, mainly in the altitude value (ΔH = ± 2.758 m).
