= GBGP software =

This is the feature request, issue and bug tracking wiki website for the '''Ground-Based GNSS Package''' (GBGP).

It comprises software (as source code) and supporting build and test scripts, data files and documentation to assist data suppliers to convert their native file formats to the so-called '''COST-format''' and COST-format files to WMO '''BUFR''' for dissemination via the GTS. The tools include comprehensive data checking, optionally enhanced with checks against a dynamic meta-data database. 

The ROM SAF project wiki page for team members is located [https://trac.romsaf.org/wiki here].

GBGP basic code is heavily based on the Met Office's ''GWVBUFR'' package originally developed for the EUMETNET ''E-GVAP'' project, but with the build system, testing and formal release procedures and user support (Help Desk) following those of the ROPP ROM SAF deliverable. The first public version of GBGP, GBGP-1.0, was released in June 2019.  No further development is planned.  GBGP support is available through the ROM SAF helpdesk.

The GBGP deliverable source code is provided in a single module (''tarball''), consisting of:
 * '''utils'''      : generic low-level utility routines
 * '''lib'''        : GB-GNSS data-specific interfaces
 * '''tools'''      : command-line conversion and encoder tools
 * '''scripts'''    : supporting shell scripts
 * '''data'''       : run-time data files
 * '''tests'''      : user-level tests
 * '''docs'''       : user documentation

Supporting modules for the source code, documentation and testing are:
 * '''gbgp_src'''   : source code, build and configure scripts for GBGP and dependency packages
 * '''gbgp_doc'''   : user and project documentation for GBGP
 * '''gbgp_test'''  : GBGP 'Test Folder' system
 
Further information on GBGP, including the Release Notes, Overview and User Guide, is available from the [http://www.romsaf.org/gbgp/ GBGP page of the ROM SAF website].
