Avaliação Do Desempenho Dos Sistemas GPS E Glonass No Posicionamento Por Ponto Preciso, Combinados E Individualmente.

Abstract: Resumo:Este trabalho visa avaliar o desempenho dos sistemas GLONASS (Global'naya Navigatsionnay Sputnikovaya Sistema), GPS (Global Positioning System) e o uso combinado de ambos sistemas em diferentes latitudes, utilizando o serviço de Posicionamento por Ponto Preciso CSRS-PPP. Para isso foram selecionadas 16 estações da rede IGS (International GNSS Service), das quais foram utilizados os dados GNSS no formato RINEX do mês de agosto de 2014 e editados no TEQC (Translation, Editing, and Quality Check), obtendo … Show more

“…It is important to highlight that the collection time used in the first data set of the present paper was 30 minutes, and that the region considered in the paper quoted presents lower ionospheric impact. Ventorim and Dal Poz (2016) also used CSRS-PPP for positioning, using IGS (International GNSS Service) stations, with 30-minute and 45-minute dual-frequency data. Accuracy obtained reached, in most part of the experiment, a decimeter to centimeter level, with some cases (with GPS-only or GLONASS-only processing) presenting metric discrepancies.…”

“…After GLONASS constellation reestablishment, more recent papers have shown the improvements that can be achieved with the use of GPS/GLONASS combined data, for instance Pan et. al (2014) and Ventorim and Dal Poz (2016).…”

“…Localization within buildings has become an urgent topic due to development of moving object navigation in production, defense industry, trade, health care, monitoring of emergency states, etc. It should be noted that obstacles and noise sources within buildings affect the GPS accuracy [1]. This is caused by ever increasing density, height and area of buildings.…”
