description The positioning in topographic and geodetic surveying with GNSS (Global Navigation Satellite System) receivers could be performed using commercial and free on-line service available on the internet. These determine the coordinates of the point of interest at epoch and geodetic reference frame of precise orbits, which in the post-processing GNSS data collected, are used and differ from the reference frame adopted for the Brazilian Geodetic System (SGB). In Brazil, only the frame SIRGAS2000 (epoch 2000.4) is applied to the coordinate determination. Therefore, it is necessary to change the reference frame and reduction of coordinate obtained from those services to the official geodetic frame adopted in the country. Thus, the computational tools to automation of procedures and report supply of the calculations, performed internally, contributes to students and users of the on-line service for post-processing GNSS data for positioning. The purpose of this study was to develop a software, named of MRefGeo, to make the change of geodetic reference frame and coordinate reduction as well as to validate the results of its use. In the MRefGeo, it is possible to choose the parameter available between the IBGE-PPP (Brazilian Institute of Geography and Statistics – Precise Point Positioning) or IERS/IGN (International Earth rotation and Reference systems Service/ Institut National de l'Information Géographique et Forestière) to change the referential and velocity models for the SIRGAS – VEMOS2009 and VEMOS2017. The experiments realized with use of MRefGeo showed that results are in agreement, at the millimeter level, with those provide by the ETRF/ITRF coordinate transformation on-line tool used in these operations.

Estes, determinam as coordenadas dos pontos de interesse na época e referencial geodésico das efemérides precisas, às quais são usadas no pós-processamento das observáveis GNSS coletadas em campo e difere do sistema geodésico de referência adotado para o SGB (Sistema Geodésico Brasileiro). No Brasil, é empregado na determinação das coordenadas apenas a realização SIRGAS2000 (época 2000,4). É imprescindível a mudança de referencial e atualização das coordenadas para o referencial geodésico oficial no país. Assim, uma ferramenta computacional para automação dos procedimentos e fornecimento de relatório dos cálculos executados internamente, contribui para estudantes e usuários desses serviços de processamento de dados GNSS para posicionamento. O propósito deste trabalho foi desenvolver um software, nomeado de MRefGeo, para realizar a mudança de referencial geodésico e atualização das coordenadas e validar os resultados de sua utilização. No MRefGeo, é possível escolher parâmetros disponibilizados pelo IBGE-PPP (Instituto Brasileiro de Geografia e Estatística - Posicionamento por Ponto Preciso) ou pelo IERS/IGN (International Earth rotation and Reference systems Service/ Institut National de l'Information Géographique et Forestière) para mudança de referencial e modelos de velocidade para o SIRGAS - VEMOS2009 e VEMOS2017. Os resultados obtidos com MRefGeo são concordantes, a nível do milímetro, com os fornecidos pela ferramenta on-line ETRF/ITRF coordinate transformation utilizados na validação das transformações e atualizações.Universidade Federal de Uberlândia2022-02-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/5546410.14393/rbcv74n1-55464Brazilian Journal of Cartography; Vol. 74 No. 1 (2022): January/March; 84-99Revista Brasileira de Cartografia; v. 74 n. 1 (2022): Janeiro/Março; 84-991808-09360560-4613reponame:Revista brasileira de cartografia - RBC (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/55464/33296Copyright (c) 2022 Taynara Nascimento de Oliveira, Alessandro Salles Carvalhohttps://creativecommons.org/licenses/by/3.0/info:eu-repo/semantics/openAccessOliveira, Taynara Nascimento deCarvalho, Alessandro SallesOliveira, Taynara Nascimento deCarvalho, Alessandro Salles2022-06-01T13:40:05Zoai:ojs.www.seer.ufu.br:article/55464Revistahttps://seer.ufu.br/index.php/revistabrasileiracartografia/indexPUBhttps://seer.ufu.br/index.php/revistabrasileiracartografia/oairevbrcartografia@gmail.com1808-09360560-4613opendoar:2022-06-01T13:40:05Revista brasileira de cartografia - RBC (Online) - Universidade Federal de Uberlândia (UFU)false
