## Appendix A  
This appendix contains additional information about the processing options, kinematic positioning results of the North, East, and Up components, and diagrams of the semivariances and elevation-dependent patterns. The processing options to obtain the fixed phase residuals in RTKLIB are shown in Table 10. Tables 11-12 contain the Post Processed Kinematic Median Absolute Deviations (MADs) in North (A2), East (A3), and Up (A4) directions. Each contains results with no corrections applied and the reductions after applying the elevation-dependent calibrations using observations from both frequencies (\(L_{1}L_{2}\)) and using \(L_{1}\)-only observations. The semivariances of the fixed phase residuals on \(L_{1}\) and \(L_{2}\) of all antennas before and after removing the elevation-dependent antenna patterns are illustrated in Figure 10. The elevation-dependent antenna patterns are shown in Figure 10. PCOs of the RTKLIB PPK processing with and without applying PCVs can be found in Figure 11.  
Figure 11: Semivariogram maps of the residuals of all investigated antennas on \(L_{1}\) (**left**) and \(L_{2}\) (**right**). The figure on the right of each frequency illustrates the residuals after removing the elevation pattern (column elev. pattern removed) from the data. The abbreviations (c) and (r) in the antenna names correspond to the utilized mounting brackets (circular plane and rectangular bracket). Each pixel represents 4\({}^{\circ}\) in azimuth and elevation totaling a range of \(-\)30\({}^{\circ}\) to +30\({}^{\circ}\).  
**Figure A2.**_Cont._Figure 11: Elevation-dependent residuals on \(L_{1}\) (**top**) and \(L_{2}\) (**bottom**). The thin lines show the residuals obtained with a 0.1\({}^{\circ}\) averaging bin size, the thin dashed lines with 1\({}^{\circ}\) averaging bin size, and the thick lines the 5\({}^{\circ}\) averages. The terms (r) and (c) correspond to the utilized mounting brackets (circular plane and rectangular bracket).

Table 11: RTKLIB PPK East component MADs in mm using \(L_{1}\) and \(L_{2}\) data (\(L_{1}\)\(L_{2}\) column) and \(L_{1}\)-only observations (\(L_{1}\)-only column). The uncorrected results (no corr.) are shown on the left. The columns on the right (\(\Delta\) corrected) show the MAD decrease (indicated by a ‘-’ sign) after applying the elevation-only based calibrations with the averaging resolutions 0.1\({}^{\circ}\), 1\({}^{\circ}\), and 5\({}^{\circ}\).
