A decade of improvements and new development of tools for observation statistics, standard point positioning, clock-jumps and cycle-slip detection and other interruptions over all constellations, frequencies and signals, satellite elevations and azimuths, elevation-specific histograms, satellite ascending/descending times for horizon and user elevation cut-off, pseudo-range multipath and noise, carrier-phase signal-to-noise ratio, data gaps and small data pieces and other useful lists and statistics allow us to analyze in detail the GNSS data collected for one of the main research subjects resulted from the September 2013 unique seismic swarm event that occurred in Romania. Open-source software such as: G-Nut/Anubis (Geodetic Observatory Pecný), RTKLIB, gLAB (European Space Agency) and commercial software like: Leica Spider QC, Leica Geo Office are used for quality control over all available data of the Ph.D. thesis called “An integrated GNSS and seismotectonic study of the NW Galati seismogenic area”. The main purpose of the paper is currently the quantity and quality monitoring of all available GNSS data achieved in 4 years of continuous monitoring along with the solutions obtained from the 4 GPS measuring campaigns (2013-2016), i.e. signals, frequencies and satellite constellations.
