Table 3: Shapiro-Wilk normality test results for GNSS positioning bias. Positioning bias from the repetitions of particular GNSS corrections resulted in a high correlation for all four varieties, constantly producing values higher than 92% (Table 5). The strongest mutual relationship was observed between CROPOS and Base station observations, with a mean [PERSON]'s correlation coefficient of 0.948. SBAS also produced a relatively high correlation with both high-precision GNSS RTK corrections, while the mobile device produced a wide range of lower correlation values, indicating low repeatability of the positioning accuracy results. \begin{table}
