---------------------------------------------------------------------- ntripserver ---------------------------------------------------------------------- (c) German Federal Agency for Cartography and Geodesy (BKG), 2002-2021 Files in ntripserver.zip ------------------------ - makefile: preconfigured makefile for convenient installation - ntripserver.c: c source file - README: Readme file for the ntripserver program NTRIP ----- The ntripserver is a HTTP client based on "Networked Transport of RTCM via Internet Protocol" (NTRIP). This is an application-level protocol streaming Global Navigation Satellite System (GNSS) data over the Internet. NTRIP Version 1.0 is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are enhanced to GNSS data streams. The primary motivation for NTRIP Version 2.0 is to develop a fully HTTP-compatible Internet protocol standard that would work with proxy servers and to add an optional data transport via UDP. Hence, one NTRIP Version 2.0 transport approach is still based on HTTP1.1 on top of TCP. The second NTRIP Version 2.0 transport approach is based on both, the Internet Standard Protocol RTSP (Real Time Streaming Protocol) for stream control on top of TCP and the Internet Standard Protocol RTP (Real Time Transport Protocol) for data transport on top of connectionless UDP. NTRIP is designed for disseminating differential correction data (e.g in the RTCM-104 format) or other kinds of GNSS streaming data to stationary 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: NTRIP clients, NTRIP servers and NTRIP casters. The NTRIP caster is the actual HTTP server program whereas NTRIP client and NTRIP server are acting as HTTP clients. ntripserver ----------- The program ntripserver is designed to provide real-time data from a single NTRIP source running under a POSIX operating system. The purpose of this program is to pick up a GNSS data stream (Input, Source) from either 1. a Serial port, or 2. an IP server, or 3. a File, or 4. a SISNeT Data Server, or 5. a UDP server, or 6. an NTRIP Version 1.0 Caster 7. an NTRIP Version 2.0 Caster in HTTP mode and forward that incoming stream (Output, Destination) to either 1. an NTRIP Version 2.0 Caster via TCP/IP (Output, Destination), or 2. an NTRIP Version 2.0 Caster via RTSP/RTP (Output, Destination), or 3. an NTRIP Version 2.0 Caster via plain UDP (Output, Destination), or 4. an NTRIP Version 1.0 Caster, or 5. an IP server via TCP/IP Installation ------------ To install the program run - gunzip ntripserver.tgz - tar -xf ntripserver.tar - make, or - make debug (for debugging purposes). To compile the source code on a Windows system where a mingw gcc compiler is available, you may like to run the following command: - gcc -Wall -W -O3 -DWINDOWSVERSION ntripserver.c -DNDEBUG -o ntripserver -lwsock32, or - mingw32-make, or - mingw32-make debug The executable will show up as ntripserver on Linux or ntripserver.exe on a Windows system. Usage ----- The user may call the program with the following options: ./ntripserver [OPTIONS] -h|? print this help screen -E <ProxyHost> Proxy server host name or address, required i.e. when running the program in a proxy server protected LAN, optional -F <ProxyPort> Proxy server IP port, required i.e. when running the program in a proxy server protected LAN, optional -R <maxDelay> Reconnect mechanism with maximum delay between reconnect attemts in seconds, default: no reconnect activated, optional -M <InputMode> Sets the input mode (1 = Serial Port, 2 = IP server, 3 = File, 4 = SISNeT Data Server, 5 = UDP server, 6 = NTRIP1 Caster, 7 = NTRIP2 Caster in HTTP mode), mandatory <InputMode> = 1 (Serial Port): -i <Device> Serial input device, default: /dev/gps, mandatory if <InputMode>=1 -b <BaudRate> Serial input baud rate, default: 19200 bps, mandatory if <InputMode>=1 -f <InitFile> Name of initialization file to be send to input device, optional <InputMode> = 2|5 (IP port | UDP port): -H <ServerHost> Input host name or address, default: 127.0.0.1, mandatory if <InputMode> = 2|5 -P <ServerPort> Input port, default: 1025, mandatory if <InputMode>= 2|5 -f <ServerFile> Name of initialization file to be send to server, optional -x <ServerUser> User ID to access incoming stream, optional -y <ServerPass> Password, to access incoming stream, optional -B Bind to incoming UDP stream, optional for <InputMode> = 5 <InputMode> = 3 (File): -s <File> File name to simulate stream by reading data from (log) file, default is /dev/stdin, mandatory for <InputMode> = 3 <InputMode> = 4 (SISNeT Data Server): -H <SisnetHost> SISNeT Data Server name or address, default: 131.176.49.142, mandatory if <InputMode> = 4 -P <SisnetPort> SISNeT Data Server port, default: 7777, mandatory if <InputMode> = 4 -u <SisnetUser> SISNeT Data Server user ID, mandatory if <InputMode> = 4 -l <SisnetPass> SISNeT Data Server password, mandatory if <InputMode> = 4 -V <SisnetVers> SISNeT Data Server Version number, options are 2.1, 3.0 or 3.1, default: 3.1, mandatory if <InputMode> = 4 <InputMode> = 6|7 (NTRIP Version 1.0|2.0 Caster): -H <SourceHost> Source caster name or address, default: 127.0.0.1, mandatory if <InputMode> = 6|7 -P <SourcePort> Source caster port, default: 2101, mandatory if <InputMode> = 6|7 -D <SourceMount> Source caster mountpoint for stream input, mandatory if <InputMode> = 6|7 -U <SourceUser> Source caster user Id for input stream access, mandatory for protected streams if <InputMode> = 6|7 -W <SourcePass> Source caster password for input stream access, mandatory for protected streams if <InputMode> = 6|7 -O <OutputMode> Sets output mode for communication with destination caster / server 1 = http : NTRIP Version 2.0 Caster in TCP/IP mode 2 = rtsp : NTRIP Version 2.0 Caster in RTSP/RTP mode 3 = ntrip1: NTRIP Version 1.0 Caster 4 = udp : NTRIP Version 2.0 Caster in Plain UDP mode 5 = tcpip : IP server in TCP/IP mode Defaults to NTRIP1.0, but will change to 2.0 in future versions Note that the program automatically falls back from mode rtsp to mode http and further to mode ntrip1 if necessary. -a <DestHost> Destination caster/server name or address, default: 127.0.0.1, mandatory -p <DestPort> Destination caster/server port, default: 2101, mandatory -m <DestMount> Destination caster mountpoint for stream upload, only for NTRIP destination casters, mandatory -n <DestUser> Destination caster user ID for stream upload to mountpoint, only for NTRIP Version 2.0 destination casters, mandatory -c <DestPass> Destination caster password for stream upload to mountpoint, only for NTRIP destination casters, mandatory -N <STR-record> Sourcetable STR-record optional for NTRIP Version 2.0 in RTSP/RTP and TCP/IP mode Example1: Reading from serial port and forward to NTRIP Version 1.0 Caster: ./ntripserver -M 1 -i /dev/ttys0 -b 9600 -O 2 -a euref-ip.net -p 2101 -m Mount2 -n serverID -c serverPass Example2: Reading from NTRIP Version 1.0 Caster and forward to NTRIP Version 2.0 ./ntripserver -M 6 -H euref-ip.net -P 2101 -D Mount1 -U clientID -W clientPass -O 1 -a www.goenet-ip.fi -p 2101 -m Mount2 -n serverID -c serverPass NTRIP Caster password and mountpoint ------------------------------------ Feeding data streams into the NTRIP system using the ntripserver program needs a password (and a user ID for NTRIP Version 2.0) and one mountpoint per stream.
