Legend:

• RMS: r.m.s. of N,E,U standard positioning (shifted by 10m) repeated at 15 min interval in a single-epoch stand-alone solution by GPS, GLONASS using concantenated navigation messages (yellow: problematic epochs)
• CRD: coordinate time-series from GPS, GLONASS daily mean positions (shifted by 10m for constellations) during a year (yellow: problematic epochs, black: too large outliers)
• MPT: assessments of code multipath detection for all constellations, signals and frequencies
• PRE: number of identified cycle-slips, clock-jumps, data gaps or small data pieces (y log-scale)
• STT: number of satellites provided by system, number of RINEX present vs. header observation types
• SUM: number of existing/usable epochs and excluded code/phase observations (due to a single freq, a few satellites etc.)
