Posicionamento multi-GNSS

Abstract: Os GNSS (Global Navigation Satellite Systems) têm ganhado bastante visibilidade nas últimas duas décadas, sendo atualmente aplicados em diversas atividades, as quais vão muito além do posicionamento e navegação; algumas delas requerem alta acurácia (centimétrica a milimétrica), como o monitoramento de estruturas e a agricultura de precisão. Para atender a estas necessidades, diferentes métodos de posicionamento foram desenvolvidos, como o posicionamento por ponto (simples e preciso) e o posicionamento relativo… Show more

“…Other GNSS processing parameters can be neglected or estimated depending on the PPP variant used. Among these noteworthy parameters, it is essential to highlight tropospheric delays which can be estimated along with horizontal tropospheric gradients (Morel et al 2021), slant ionospheric delays (STEC) (Oliveira Jr 2017), clock biases or even inter-system biases when processing multiple GNSS (multi-GNSS) constellations data (Setti Jr et al 2020;Li et al 2022). Precise ephemerides and clocks have to be obtained from external founts, like IGS.…”

“…As the multi-frequency and multi-constellation (MFMC) positioning offers a range of advantages compared to the GPS positioning (Kouba, Lahaye & Tétreault 2017;Montenbruck et al 2017;Setti Júnior et al 2020), the Brazilian Network for Continuous Monitoring of the GNSS Systems (RBMC -Rede Brasileira de Monitoramento Contínuo dos Sistemas GNSS), has been updating itself for a MCMF network. Currently, 48 stations track and record measurements from three or four of the global constellations.…”
