************************ * Standard NtripCaster * ************************ Introduction ~~~~~~~~~~~~ The Standard NtripCaster is a software written in C Programming Language for disseminating GNSS real-time data streams via Internet. For details of Ntrip (Networked Transport of RTCM via Internet Protocol) see its documentation available from http://igs.ifag.de/index_ntrip.htm. You should understand the Ntrip data dissemination technique when considering an installation of the software. The Standard NtripCaster software has been developed within the framework of the EUREF-IP project, see http://www.epncb.oma.be/euref_IP. It is derived from the ICECAST Internet Radio as written for Linux platforms under GNU General Public License (GPL). Please note that whenever you make software available that contains or is based on your copy of the Standard NtripCaster, you must also make your source code available - at least on request. The Standard NtripCaster software has been tested so far on various Suse, Debian, Gentoo, and Redhat (up to Enterprise 5) Linux distributions. Note that the software may not run today on some other Linux distributions of recent date. Version 0.1.5 of the Standard NtripCaster supports a maximum of 50 NtripServers and 100 NtripClients simultaneously, see http://igs.ifag.de/pdf/NtripImplementation.pdf for technical details. Ntrip Version 1.0 is an RTCM standard for streaming GNSS data over the Internet. Offering the Standard NtripCaster Version 0.1.5 is part of BKG’s policy to help distributing this standard. RTCM may decide to issue further Ntrip versions as the need arises. Thus, it might be necessary to modify the Standard NtripCaster Version 0.1.5 in the future. Ntrip is already part of some GNSS equipment available today. You may like to ask your vendor about the Ntrip capability of your GNSS hardware or software. Although Standard NtripCaster Version 0.1.5 should satisfy most needs, we continue to work on a high-performance version with enhanced functionality. This Professional NtripCaster Version is meant for professional/commercial service providers. Following your installation, we would appreciate if you could inform us about the IP address of your Standard NtripCaster. We intend to keep track of the upcoming global NtripCaster network, which allows linking them through appropriate entries in the corresponding configuration files. Note that the BKG does not give any warranty regarding the function of the Standard NtripCaster Version 0.1.5. Moreover, the BKG disclaims any liability nor responsibility to any person or entity with respect to any loss or damage caused, or alleged to be caused, directly or indirectly by the use of Standard NtripCaster Version 0.1.5. Please note that due to limited resource we are not able to give any support concerning installation and maintanance of the software. Installation ~~~~~~~~~~~~ To install the NtripCaster do the following: - unzip the software in a separate directory - run "./configure" (if you do not want the server to be installed in "/usr/local/ntripcaster" specify the desired path with "./configure --prefix=") - run "make" - run "make install" After that, the server files will be in "/usr/local/ntripcaster", binaries will be in "/usr/local/ntripcaster/bin", configuration files in "/usr/local/ntripcaster/conf", logs in "/usr/local/ntripcaster/logs" and templates in "/usr/local/ntripcaster/templates" (or in your desired path correspondingly). Go to the configuration directory and rename "sourcetable.dat.dist" and "ntripcaster.conf.dist" to "sourcetable.dat" and "ntripcaster.conf". Edit both files according to your needs. For details about "sourcetable.dat" see file "NtripSourcetable.doc". In the configuration file "ntripcaster.conf" you have to specify the name of the machine the server is running on (no IP adress!!) and you can adapt other settings, like the listening ports, the server limits and the access control. Now the server is ready to be run with "./ntripcaster" in the binary directory. The NtripCaster has been tested on various RedHat and Suse Linux distributions. Whatever the content of your "sourcetable.dat" finally might be, it is recommended to include the following line in that configuration file: CAS;rtcm-ntrip.org;2101;NtripInfoCaster;BKG;0;DEU;50.12;8.69;http://www.rtcm-ntrip.org/home License ~~~~~~~ NtripCaster, a GNSS real-time data server Copyright (C) 2004-2008 This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
