====================================================================== Bernese GNSS Software, Version 5.2 Last mod.: 21-Jul-2017 ---------------------------------------------------------------------- Conversion from version 5.0 to 5.2 ====================================================================== ---------------------------------------------------------------------- Changed files ---------------------------------------------------------------------- Changed formats --------------- - Station information/problem file (extensions STA and CRX in the STA directory of the campaign) Use program STA2STA to convert these files from version 5.0 (format version "0.00") to the new format ("1.01" or higher). Menu >Service >Station information files >Convert station information files - Antenna phase center correction file Use the new program ATX2PCV to read the corrections from ANTEX for all the stations contained in the station information file. Menu >Conversion >ANTEX to Bernese format - Satellite information file The new formatted file is included in the distribution, but you can also download it from ftp://ftp.aiub.unibe.ch/BSWUSER52/GEN - Constant and datum information files Files extended with the additional records are included in the distribution, but you can also download them from ftp://ftp.aiub.unibe.ch/BSWUSER52/GEN - Program input files (extension INP in ${U}/PAN or %U%\PAN directory) Use the new input files distributed with the software. You may use Menu >Config >Update program input files to update your old input files to the new version. Attention: The new input files cannot be displayed with your menu from version 5.0 anymore. New formats without converters ------------------------------ There are several more file formats that have changed from version 5.0 to version 5.2. The old formats can still be read by the programs but files stored by the program from version 5.2 cannot be handled by the version 5.0 programs. These file types are: - Coordinate and velocity files (extensions CRD and VEL in the STA directory of the campaign) - Normal equation files (extension NQ0 in the SOL directory of the campaign) - Standard orbit files (extension STD in the ORB directory of the campaign) - Observation (header) files (extensions CZH, PZH, RZH, CSH, and PSH in the OBS directory of the campaign) - DCB files may contain new record types (extension DCB in the ORB directory of the campaign) New file types -------------- - Grid files (Extension GRD in the GRD directory of the campaign) VMF1 coefficients and geophysical models - Atmospheric tidal loading (Extension ATL in the STA directory of the campaign) Extraction (done by program GRDS1S2) from a global grid for the stations to be processed. Menu >Service >Coordinate tools >Extract atmospheric tidal loading coefficients - Gravitational effect of the solid Earth tides on orbits (Extension TPO in ${X}/GEN - or %X%\GEN% - directory) To be used by ORBGEN analogue to the corrections for the ocean tides - Satellite-/receiver-specific observation type selection (in ${X}/GEN - or %X%\GEN% - directory) To select the measurement types from a RINEX 2 or a RINEX 3 observation file to be transferred for the first and second frequency into the Bernese formatted observation file - Bias exchange file (extension BIA in the ORB directory of the campaign) International exchange format for receiver/satellite code and phase biases - Event list file and Earthquake file (extensions EVL and ERQ in STA directory of the campaign) To be used to define a priori events for FODITS and to report significant events from a FODITS analysis (EVL only) Menu >Coordinate tools >Analysis of time series - SLR corrections (extension SLR in the STA directory of the campaign) To provide biases and center of mass corrections for SLR processing File types not supported anymore -------------------------------- - All file types prior version 5.0 are not supported anymore, in particular old normal equation files (extension NEQ), station renaming tables (extension STN), receiver/antenna renaming tables (extension TRN), antenna height translation tables (HTR), old abbreviation tables, etc. - Orbital element files (extention ELE) generated with version 5.0 cannot be integrated by ORBGEN of version 5.2. ---------------------------------------------------------------------- Campaign directories ---------------------------------------------------------------------- To process an existing campaign created with Bernese GPS Software Version 5.0, the whole campaign directory has to be moved (or copied) to the new campaign area. Example (UNIX command line syntax): cp -pr ${P}(V5.0)/MY_CAMP ${P}(V5.2)/MY_CAMP with ${P}(V5.0): campaign area of version 5.0 (e.g., ~/GPSDATA) ${P}(V5.2): campaign area of version 5.2 (~/GPSDATA/CAMPAIGN52) Add the campaign to the new list of campaigns (version 5.2). Menu >Campaign >Edit list of campaigns : + ${P}/MY_CAMP Menu >Campaign >Select active campaign : ${P}/MY_CAMP After applying the conversions mentioned above, the campaign files can already be processed with the new software in interactive mode or by using the example BPEs from version 5.2. ---------------------------------------------------------------------- Transfer BPEs from V5.0 to V5.2 ---------------------------------------------------------------------- A general recommendation is to start developping BPEs for version 5.2 using the distributed examples as templates. This way you can be sure that the latest features are used. Nevertheles, there might be reasons why you want to transfer your existing BPEs from V5.0 to V5.2. In this case, the user files from the BSW 5.0 user environment have to be moved (or copied) to the new user environment of BSW 5.2. Example (UNIX command line syntax): cp -pi ${U}(V5.0)/PCF/* ${U}(V5.2)/PCF # Don't overwrite files cp -pi ${U}(V5.0)/SCRIPT/* ${U}(V5.2)/SCRIPT # Don't overwrite files cp -pri ${U}(V5.0)/OPT/* ${U}(V5.2)/OPT # Don't overwrite files with ${U}(V5.0): GPSUSER area of version 5.0 (e.g., ~/GPSUSER) ${U}(V5.2): GPSUSER area of version 5.2 (~/GPSUSER52) Remarks: - PCF files with the same name have to be renamed. - The user scripts (in $U/SCRIPT) which have the same name in version 5.0 and 5.2 used for the example campaign can be skipped from copying. I.e. the scripts from version 5.2 should be used. The only exeptions might be the ???_COP and the ???_SUM scripts. - If you overwrite existing program input files in option subdirectories, the behaviour of existing BPEs may change (even after updating program input files, see next section). If you want to avoid this, you may rename option subdirectories and adapt your PCF accordingly. ---------------------------------------------------------------------- Update of the program input files ---------------------------------------------------------------------- The program input files can be updated with the tool UPDPAN. Menu >Configure >Update program input files It is recommended to select all INP files from ${X}/PAN (using "*") and updating the existing files in OPT/* to be able to run the old BPEs with the new software version. The output file from UPDPAN as well as the updated program input panels which changed should be studied carefully. ---------------------------------------------------------------------- Example: RNX2SNX_V50.PCF with new software ---------------------------------------------------------------------- The next step is to update a few input options that have changed or new ones which are required in the new version. For this purpose use the program CHNGEN. Menu >Configure >Change general options Select the panel directories ${U}/OPT/* and set a new value for the two names Satellite info -> SATELLIT.I01 Phase center ecc. -> PCV.I01 Then, some other keywords have to be changed on the next panel. Keyword Old value New value ******* ********* ********* JPLEPH DE200 DE405 ABBREV ABBREV EXAMPLE LENINTER 1.0 01 00 00 VARLNINT 6.0 06 00 00 PRINT NO 0 PRINT YES 1 BLKRET 0 NO BLKRET 1 YES This is already enough for the RNX2SNX.PCF example of the old BSW. For other BPEs there might be additional keywords to be changed. One option has been added to the program input file of RESRMS ("Create residual statistics") that has to be set manually by opening the correspondig panels. Menu >BPE >Edit PCF program input files Select RNX2SNX_V50.PCF Select all RESRMS panels (e.g. in GPSEDT and RESCHK steps) Set sampling rate of residual files to "180" Note: in your own BPEs other keywords may be affected. ---------------------------------------------------------------------- Update the models ---------------------------------------------------------------------- After verification of the results, you can now update to the latest models, e.g., reference frame IGb08 and antenna model I08. For further instructions in this matter, see Sections 20.5.3 ("Change of Reference Frame") and 20.5.4 ("Change of the Antenna Models") in the Software Documentation. ======================================================================
