Steps 3, 4 and 5 are iterative. 6 - Determination of scaling factors 7 - Loosely constrained weekly solution (a priori position for all station are constrained to 1 meters): IBG1671S.SNX 8 - Determination of the solution aligned with the IGS Reference Frame. The Datum realization is obtained through of definition of the stations listed in (3) as constraint (1E-04 m). Are used as reference the IGS weekly coordinates (IGS12P1671.SNX). This is solutions (IBG12P1671.SNX) represent the SIRGAS-CON positions for practical applications. --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- Software: --------------------------------------------------------------------------------------------- Bernese V. 5.0, UNIX platform. --------------------------------------------------------------------------------------------- RESULTS ----------------------------------------------------------------------------- 1)RESULT FILES ----------------------------------------------------------------------------- IBG1671S.SNX covariance matrix loosely constrained weekly combination IBG12P1671.SNX covariance matrix constrained weekly combination IBG1671S.SUM this text file ----------------------------------------------------------------------------- 2)EQUIPMENT INCONSISTENCIES -------------------------------------------------------------------------------------- Station PC Comments -------------------------------------------------------------------------------------- SL01 41543M001 : GNA Antenna TRM57971.00 NONE -> TRM57971.00 TZGD ----------------------------------------------------------------------------- 3)MISSING STATIONS --------------------------------------------------------------------------- Station PC Comments ----------------------------------------------------------------------------- IQQE 41708S002 CIM Missing station in CIM solution IQQE 41708S002 DGF Missing station in DGF solution SCRZ 41801M001 DGF Missing station in DGF solution IQQE 41708S002 ECU Missing station in ECU solution IQQE 41708S002 GNA Missing station in GNA solution IQQE 41708S002 IBG Missing station in IBG solution ----------------------------------------------------------------------------- 4)EXCLUDED STATIONS ---------------------------------------------------------------------------------------- Station PC Comments ---------------------------------------------------------------------------------------- CHIH 40525M001 : INE Renamed station CHI3 40525M001 -> CHIH 40525M001 ----------------------------------------------------------------------------- 5)STATISTICS OF COMBINATION Sol No. STATIONS Rms (mm)* Chi**2/DOF 1/(Chi**2/DOF) ----------------------------------------------------------------------------- CIM 93 1.64 0.67 1.493 DGF 85 1.61 0.65 1.538 ECU 58 1.62 0.65 1.538 GNA 53 2.00 1.00 1.000 IBG 119 1.88 0.88 1.136 IGA 78 1.58 0.62 1.613 INE 32 2.00 1.00 1.000 LUZ 78 1.57 0.61 1.639 URY 65 1.60 0.64 1.562 ---------------------------------------------------------------------------- COMBINATION 184 1.67 0.70 ----- * A posteriori RMS of unit weight 6)RMS WITH RESPECT TO IGS12P1671 SOLUTION in mm ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- Solution.
