Bernese GNSS Software Version 5.2 Tutorial

1.2 Directory StructureSTAT_LOG :This directory contains the station information files (e.g., from ftp://igscb.igs.org/pub/station/general). This information may be completed by the originaryinformation on the reference frame (e.g., the IGb08.snx from ftp://igscb.igs.org/pub/station/coord).It also contains (apart from the coordinates and velocities of selected IGS sites)the history of the used equipment as it has been assumed for the reference framegeneration. A comparison with the igs.snx file constructed at the IGS CentralBureau (IGSCB) from the site information files may be useful for a verification ofthe history records.COD/IGS :Orbits, Earth orientation parmeters (EOP), and satellite clock corrections are basicexternal information for a GNSS analysis. The source of the files may be theFTP server from CODE (ftp://ftp.unibe.ch/aiub/CODE or http://www.aiub.unibe.ch/download/CODE/), or the Crustal Dynamics Data Information SystemFTP server (e.g., for downloading GPS–related IGS products ftp://cddis.gsfc.nasa.gov/gnss/products and in ftp://cddis.gsfc.nasa.gov/glonass/productsfor GLONASS–related IGS products). The files are named with the GPS week andthe day of the week (apart from files containing information for the entire week, e.g.,EOP, or the processing summaries).The IGS provides GPS and GLONASS orbits only in separate files (IGS/IGL–seriesfrom the final product line) stemming from independent combination procedureswith different contributing analysis center (AC). Nevertheless, they are consistentenough to merge both files together as the first step of the processing. CODEcontributes fully combined multi–GNSS solutions to the IGS final (and ultra–rapid)product line.BSW52 :In this directory we have placed files containing external input information inBernese–specific formats. The files are neutral with respect to the data you aregoing to process. Typical examples are ionosphere maps or differential code biases(DCB) files. These files can be downloaded from http://www.aiub.unibe.ch/download/CODE/ or http://www.aiub.unibe.ch/download/BSWUSER52/ areas.REF52 :Here we propose to collect files in Bernese format which are useful for severalcampaigns (e.g., reference frame files: IGB08_R.CRD, IGB08_R.VEL). Typical examplesare station coordinate, velocity, and information files (e.g., EXAMPLE.CRD,EXAMPLE.VEL, EXAMPLE.STA, . . . , EPN.CRD). All stations of a project are containedin one file but the processing of the project’s data may be performed in differentcampaigns.MSC :This directory contains example files for the automated processing with the BPE.VMF1 :The grids for the Vienna Mapping Function (VMF1) are located in a separate directory.The files can be downloaded from http://ggosatm.hg.tuwien.ac.at/DELAY/GRID/VMFG/. They are not used for the examples but it shall indicate that for othertypes of files other directories may be created.Bernese GNSS Software, Version 5.2 Page 5
