     17NTRIP
    1718-----
    18 NtripServerLinux is a HTTP client based on "Networked Transport of
    19 RTCM via Internet Protocol" (Ntrip). This is an application-level
    20 protocol streaming Global Navigation Satellite System (GNSS) data over
    21 the Internet. Ntrip is a generic, stateless protocol based on the
    22 Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are enhanced
    23 to GNSS data streams.

     26NTRIP is designed for disseminating differential correction data
    2627(e.g in the RTCM-104 format) or other kinds of GNSS streaming data to

    2930supports wireless Internet access through Mobile IP Networks like GSM,
    3031GPRS, EDGE, or UMTS.

    32 Ntrip is implemented in three system software components:

     34NTRIP clients, NTRIP servers and NTRIP casters. The NTRIP caster is the
     35actual HTTP server program whereas NTRIP client and NTRIP server are
    3536acting as HTTP clients.

    37 NtripServerLinux
    38 ----------------
    39 The program NtripServerLinux is designed to provide real-time data
    40 from a single NtripSource running under a Linux operating system.
    41 Basically the NtripServerLinux grabs a GNSS byte stream
    42 from a serial port or tcpsocket port and sends it off over an
    43 Internet TCP connection to the NtripCaster.
    4438
    45 Mind that the NtripServerLinux may not be able to handle your
    46 proxyserver. When using it in a proxy-protected Local Area Network
    47 (LAN), a TCP-relay may have to be established connecting the
    48 proxyserver and the NtripCaster. Establishing the Internet
    49 connection for an NtripServerLinux by using an Internet Service
    50 Provider (ISP) is an alternative.
     39ntripserver
     40-----------
     41The program ntripserver is designed to provide real-time data
     42from a single NTRIP source running under a Linux operating system.
     43
     44Basically the ntripserver grabs a GNSS byte stream (Input, Source)
     45from either
     46
     471. a Serial port, or
     482. an IP server, or
     493. a File, or
     504. a SISNeT Data Server, or
     515. a UDP server, or
     526. an NTRIP Version 1.0 Caster
     53
     54and forwards that incoming stream to either
     55
     561. an NTRIP Version 2.0 Caster via TCP/IP (Output, Destination), or
     572. an NTRIP Version 2.0 Caster via RTSP/RTP (Output, Destination), or
     583. an NTRIP Version 1.0 Caster.
     59
     60Please note, the options to support NTRIP Version 2.0 are currently still
     61under development and should be used with care. Keep in mind that details
     62of the NTRIP Version 2.0 transport protocol are still under discussion
     63and may be changed.

    10083
    101 There are additional options to support NTRIP version 2.0. These are currently
    102 still under development and should be used with care.
     84-E <ProxyHost>   Proxy server host name or address, required i.e. when
     85                 running the program in a proxy server protected LAN,
     86                 optional

    104 Example:

     94   3 = File, 4 = SISNeT Data Server, 5 = UDP server, 6 = NTRIP Caster),
     95   mandatory
    10696
    107 It is recommended to start NtripServerLinux through shell script
    108 StartNtripServerLinux. This shell script ensures that
    109 NtripServerLinux reconnects to the NtripCaster after a broken
    110 connection.
     97   <InputMode> = 1 (Serial Port):
     98   -i <Device>      Serial input device, default: /dev/gps, mandatory if

    118 Server password and mountpoint
    119 ------------------------------
    120 Feeding data streams into the Ntrip system using the
    121 NtripServerLinux program needs a server password and one mountpoint
    122 per stream. Currently this is available from
    123 euref-ip@bkg.bund.de (see "NtripProvider.doc").

    124116
    125 Station Logfile
    126 ---------------
    127 A user of your data stream may need detailed information about the
    128 GNSS hardware and firmware that generates your signal. This
    129 information will be made available through a station logfile. Please
    130 find an example station logfile in "SiteLogExample.txt". Create a
    131 similar logfile describing your GNSS receiver hardware and firmware
    132 and include the requested information as far as it is available for
    133 you. Note that the form of this document follows an IGS
    134 recommendatation that can be downloaded from
    135 ftp://igscb.jpl.nasa.gov/pub/station/general/sitelog_instr.txt
    136 The content of your station logfile has to be kept up to date.
    137 Thus, please inform the NtripCaster operator about all changes at
    138 your station by sending an updates version of your station logfile.
    139 Providing a station logfile is not necessary in case you generate
    140 a Virtual Reference Station (VRS) data stream.
