Abstract

GNSS (Global Navigation Satellite System) has being widely employed in several applications, both scientific and commercial. Its use has become popular and the trend is to be used by a large number of users. Something that has been widely explored is the GNSS ability of providing highly accurate coordinates, depending on the positioning method and software employed. In this context, a very used software is called Bernese. Bernese is a high performance scientific software used to process GNSS data and developed at AIUB (Astronomical Institute of the University of Bern). It is, e.g., used by (Center for Orbit Determination in Europe) for its activities related to IGS (International GNSS Service). Nationally, he is employed by IBGE (Brazilian Institute of Geography and Statistics - Instituto Brasileiro de Geografia e Estatística) to estimate coordinates in order to homologate reference stations from RBMC (Brazilian Network for Continuous Monitoring). In this research, the main goal is to study, manipulate and use the software to realize high precision GNSS positioning. Thus, the Bernese software will be employed in GNSS network data processing, using different processing strategies provided by the software. In addition, it is intended to start the software automation, which would bring great collaboration with Space Geodesy research area.
