This is an application-level protocol streaming Global Navigation Satellite System (GNSS) data over the Internet. Ntrip is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are enhanced to GNSS data streams.Ntrip is designed for disseminating differential correction data (e.g in the RTCM-104 format) or other kinds of GNSS streaming data tostationary or mobile users over the Internet, allowing simultaneous PC,Laptop, PDA, or receiver connections to a broadcasting host. Ntrip supports Wireless Internet access through Mobile IP Networks like GSM, GPRS, EDGE, or UMTS.Ntrip is implemented in three system software components: NtripClients, NtripServers and NtripCasters. The NtripCaster is the actual HTTP server program whereas NtripClient and NtripServer are acting as HTTP clients.NtripLinuxClient----------------This Linux/UNIX NtripClient program is written under GNU General Public License in C programming language. The program reads data from an Ntrip Broadcaster and writes on standard output for further redirection of data to a file or COM-port. PLEASE NOTE THAT THIS PROGRAM VERSIONDOES NOT HANDLE POTENTIALLY OCCURRING INTERRUPTIONS OF COMMUNICATIONOR NETWORK CONGESTION SITUATIONS. Its distribution may stimulatethose intending to write their own client program.Call the program with following arguments:NtripLinuxClient -d mountpoint                 -s Ntrip Broadcaster IP adress                          -p password                 -r Ntrip Broadcaster Port number                 -u username		 -n NMEA string for sending to server		 -b output bitrateor using an URL:./NtripLinuxClient ntrip:mountpoint[/username[:password]][@server[:port]][;nmea]		 The argument '-h' will cause a HELP on the screen.Without any argument NtripLinuxClient will provide the a table ofavailable resources (source table).Compilation/Installation------------------------Please unzip the archive and copy its contents into an appropriatedirectory. Compile the source code under Linux through entering e.g.the command 'cc -o NtripLinuxClient NtripLinuxClient.c'.Registration------------Some of the data streams (mountpoints) from an NtripCaster may beavailable for test, demonstration, and evaluation purposes andaccessible without authentication/authorization. For accessing otherdata streams (mountpoints) the user needs a user-ID and auser password. Authorization can be provided for a single stream,for a group of streams (network) or for all available streams.Currently, registration can be requested via the registration formon http://igs.ifag.de/ntrip/ntrip_register.htm.Ntrip Broadaster Address and Port---------------------------------The current Internet address of the Ntrip Broadcaster iswww.euref-ip.net. The port number is 80.Disclaimer----------Note that this NtripLinuxClient program is for experimental useonly. 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 and application of the Ntrip technology.Further Information-------------------http://igs.ifag.de/index_ntrip.htmeuref-ip@bkg.bund.de
