Abstract

The processing of Global Navigation Satellite System (GNSS) data by scientific software is a growing need in Space Geodesy studies. However, deal with these, in general, is not always an easy task. Thereby, a system that helps in processing is important for researches efficiency of the entire user community. This paper discusses the implementation and validation of an online system for GNSS data processing and analysis, which enables sharing the use of Bernese GNSS software at UFV. The GNSS-UFV system is available at http://gnss.ufv.br. This system is prepared to receive, assist and manage requests for GNSS data processing with Precise Point Position (PPP) and Relative methods by Bernese GNSS software, and then forward and store processing results. The GNSS-UFV PPP was tested and compared with IBGE-PPP service. The average planimetrics resultants accuracy was the same for both systems, 0.013m, while the average altimetrics components accuracy was 0.020m for the IBGE-PPP and 0.018m for the GNSS-UFV. The GNSS-UFV Relative method was compared with AUSPOS service, where the average planimetrics resultants accuracy was 0.009m and 0.010m and the average altimetrics components accuracy was 0.021m and 0.026m for AUSPOS and GNSS-UFV, respectively.
