6 Terminal Session: ThursdayThe program computes the arithmetic mean for all station coordinates. The difference ofeach individual coordinate set to this mean value and the overall RMS are reported in thefollowing section of the program output:NUM STATION #FIL C RMS 1 2 3 4------------------------------------------------------------71 GANP 11515M001 4 N 8.47 -6.77 -7.87 6.95 7.69E 11.51 -9.89-10.03 10.55 9.37U 2.45 1.20 1.99 0.35 -3.5489 HERT 13212M010 4 N 8.73 -7.34 -7.77 7.50 7.61E 9.47 -8.70 -7.67 8.05 8.33U 3.30 -2.59 -0.45 -1.73 4.77106 JOZ2 12204M002 4 N 8.08 -6.81 -7.17 7.09 6.90E 12.48 -10.36-11.25 11.03 10.58U 3.77 2.46 3.94 -2.67 -3.74123 LAMA 12209M001 4 N 8.38 -7.25 -7.22 6.44 8.02E 11.80 -10.32-10.11 10.20 10.23U 2.61 2.91 0.71 -0.22 -3.39136 MATE 12734M008 4 N 11.67 -10.26 -9.91 10.88 9.29E 13.91 -11.89-12.19 11.80 12.29U 1.76 -0.32 -0.28 2.41 -1.81174 ONSA 10402M004 4 N 8.18 -7.03 -7.10 6.31 7.82E 10.30 -8.67 -9.15 8.52 9.30U 4.37 -2.75 -4.30 5.30 1.74193 PTBB 14234M001 4 N 9.07 -6.96 -8.70 8.03 7.63E 11.35 -9.75 -9.91 9.52 10.14U 1.55 -1.83 0.36 -0.40 1.88236 TLSE 10003M009 4 N 9.21 -8.58 -7.34 7.65 8.27E 11.39 -10.13 -9.58 9.63 10.09U 2.18 -0.65 -2.70 0.98 2.37258 WSRT 13506M005 4 N 9.76 -8.36 -8.54 8.87 8.03E 10.30 -8.69 -9.15 8.85 8.98U 2.14 0.68 -1.48 -1.91 2.72259 WTZR 14201M010 4 N 8.99 -7.84 -7.73 7.52 8.05E 11.43 -10.13 -9.66 9.58 10.21U 2.22 0.31 2.55 -0.02 -2.85260 WTZZ 14201M014 4 N 8.91 -7.69 -7.73 7.34 8.08E 13.18 -11.43-11.39 11.00 11.82U 2.35 -2.97 -0.07 2.78 0.26270 ZIM2 14001M008 4 N 9.40 -7.99 -8.27 7.63 8.63E 11.46 -9.86 -9.99 9.86 9.99U 1.05 -1.36 -0.29 0.73 0.92272 ZIMM 14001M004 4 N 9.46 -8.20 -8.18 8.31 8.08E 10.97 -9.55 -9.44 9.68 9.31U 0.36 0.38 -0.27 0.23 -0.35------------------------------------------------------------While interpreting this output, keep in mind that the first two columns and the last twocolumns refer to different epochs (see warning message). The difference between theseepochs is about one year. Obviously, station velocities need to be estimated (this will bedone in the next step described in Section 6.5).Page 88AIUB
6.4 Compute the Reduced Solution of the SessionsIf reliable velocities for all stations are available they can be introduced:You may check the influence on the repeatability by your own.This output may be used for quality assessment. Stations with a problem in oneor more sessions can be identified and excluded from the final ADDNEQ2 solution byadding them to section TYPE 003: STATION PROBLEMS in the station information file(${P}/INTRO/STA/EXAMPLE.STA). All parameters of these stations will be pre–eliminatedbefore the normal equations are stacked and, therefore, also before the solution is computed.6.4 Compute the Reduced Solution of the SessionsIf one or more stations have to be excluded from the session solution or if the datumdefinition of the solution is still not acceptable, the final solution of the session has to bere–computed by repeating the ADDNEQ2 in Section 6.2. Finally, the result files for thefinal solution of the session are:${P}/INTRO/SOL/FIN$YD+0.NQ0,${P}/INTRO/STA/FIN$YD+0.CRD, and${P}/INTRO/ATM/FIN$YD+0.TRP.It is preferable for the velocity estimation to have smaller normal equation files containingonly the coordinate parameters for each session. In addition, we generate a coordinateSolution INdependent EXchange format (SINEX) file (in NEQ representation) as the finalsolution of the day, so the troposphere parameters have to be pre–eliminated before thesolution is computed. We introduce the station coordinates (${P}/INTRO/STA/FIN$YD+0.CRD) obtained with the minimum constraint solution in the previous run of ADDNEQ2and constrain the solution to these coordinates.To generate these reduced NQ0 files and the SINEX file, the execution of ADDNEQ2 hasto be repeated with the following changes in the input options:Bernese GNSS Software, Version 5.2 Page 89
