9. Combination of Solutions The point code is incremented from A to B or C for station specific parameters related to stations with the same 4-character abbreviation but different DOMES code. If 4-character abbreviation and DOMES code are equal the solution ID is incremented. Option “Truncate all NEQ station names after position 14” in panel “ADDNEQ2 3.3: Options 3” (see Figure 9.11) allows it to disregard characters in the station names after position 14 in order to eliminate characters B, C, etc., following the DOMES code and indicating different coordinate solutions. Instead of NO and YES a number may be specified giving the position after which the station names shall be truncated. Truncated station names are used for all output files, not only for SINEX. The a priori constraint matrix in the SINEX file (“SOLUTION/MATRIX APRIORI” block) needs to be regular. This is not the case if the datum is defined using a free network constraint or if not all stations are constrained. If YES is selected for option “Regularize a priori constraint matrix” (Figure 9.11), an additional weight of 1e-7 is put to the diagonal of the matrix (as well as to the solution matrix). Alternatively you may specify another value as regularization constraint in the same field. Option “Include ADDNEQ1-style statistics block” allows to include a comment block containing statistical information in the SINEX output file as it was generated by the old ADDNEQ program and is available only for backwards compatibility. 9.4.9.2 Import of SINEX Files The program SNX2NQ0 (”Menu>Conversion>SINEX to normal equations”) allows it to convert a list of SINEX files to binary normal equation files. The program supports SINEX versions 0.05 to 2.00. See also Section 4.6. The program inverts the (constrained) correlation or covariance matrix (block “SOLUTION/MATRIX ESTIMATE”) as well as the constraint matrix (block “SOLUTION/MATRIX APRIORI”) before subtracting the second from the first matrix to obtain the unconstrained normal equation matrix. Alternatively the program may read normal equations directly from SINEX if the corresponding block “SOLUTION/NORMAL EQUATION MATRIX” is available. In option “SOLUTION block for generating normal equation system” in panel “SNX2NQ0 2: Options” the requested SINEX source block can be selected. Option “Reconstruct original NEQ info from Bernese SINEX data” makes it possible to reconstruct the original normal equation information from SINEX files written by the Bernese GPS Software. The “SOLUTION/STATISTICS” block is used for Bernese SINEX files written by the program ADDNEQ2, and the SINEX header information is used for Bernese SINEX files written by the old program version ADDNEQ. If the SINEX files are not Bernese SINEX files the statistical information might be not extracted correctly. The unit weight specified in option “A priori sigma of unit weight” usually corresponds to the weight of the zero-difference L1 phase observable (at zenith). If you reconstruct the original normal equation information from Bernese SINEX files, this a priori sigma is not used but extracted from the SINEX data. With option “Generate CRD and VEL” in panel “SNX2NQ0 2: Options” enabled station coordinates and (if available) velocities are extracted from the SINEX “SOLUTION/ESTIMATE” block and written to file in Bernese format. For each input SINEX file a Bernese coordinate and velocity file is written with the same name but different extension. Page 206 AIUB
9.4 The Program ADDNEQ2 With program SNX2STA (”Menu>Conversion>SINEX to station information” station information may be extracted from a SINEX file and written to a station information file. The information extracted includes station name and description (from “SITE/ID” block), receiver name and unit number (from “SITE/RECEIVER” block), antenna name and serial number (from “SITE/ANTENNA” block), as well as antenna eccentricity (from “SITE/ECCENTRICITY” block). All four blocks have to be present in the SINEX file. You may specify a station selection file containing a list of station names. Only stations specified in this input file will be included in the output station information file. Note that only the first 14 characters of the station names are used to identify the stations. In any case it is important to check the content of the output file and, if necessary, to adapt or complement its content. 9.4.10 Conversion of Normal Equation Files 9.4.10.1 Conversion from and to ASCII In order to allow the transfer of binary normal equation files between platforms that are binary incompatible (or for the rare cases where a user likes to check the content of a normal equation file with an ASCII editor) the program NEQ2ASC (”Menu>Conversion>Normal equations (binary/ASCII)”) is available. The program allows it to convert normal equation files in both directions. A list of files (binary or ASCII) may be selected for conversion in a single run. 9.4.10.2 Old Normal Equation Files from ADDNEQ The main difference between the normal equation files written by ADDNEQ2 and by its predecessor ADDNEQ consists in the fact that the old normal equation files were written including the constraints while the new normal equation files are stored without any constraints. Numerical problems when changing constraints in a later run are thus avoided. Because users may have archived normal equation files written by earlier versions of the Bernese GPS Software, Version 5.0 contains a converter, program NEQ2NQ0 (”Menu >Conversion>Version 4.2 to 5.0>Normal equations (old to new format)”), allowing to convert a list of old binary normal equation files (default extension NEQ) to the new binary format (default extension NQ0). The use of the program is straightforward. The phase center eccentricity name is included for information in the new normal equation file but not in the old file and has thus to be specified in the input panel. Before converting old normal equation files to the new format users may have to transfer the files to a new platform that may be binary incompatible. It may, e.g., happen, that a user generated an archive of old normal equation files with Version 4.2 on a PC and wants now to access these files with Version 5.0 on a Linux system or with the software compiled with a new compiler. In order to make the necessary conversions possible, the old normal equation ASCII-to-binary converter NEQFMT is available in Version 5.0 (”Menu>Conversion >Version 4.2 to 5.0>Old normal equations (binary/ASCII)”. A conversion procedure may then look like: (1) Convert old normal equations from binary to ASCII on the old system using NEQFMT from Version 4.2 . Bernese GPS Software Version 5.0 Page 207
