      All,

      As a follow up to my last e-mail, we have made some
      significant changes to the SOPAC NtripCaster.

      Access is through 132.239.152.74:2100
      User-ID: SCIGN
      Password: RealTime
      NtripClient available from
      http://igs.ifag.de/index_ntrip.htm

      You can access the data stream by All or by individual
      County (i.e., Orange, Riverside, Imperial, San Diego).

      Other changes:
      RTCM data are in version 2.3
      Access to other ports at  SOPAC have not changed
      RTCM version 2.2 is available from the Enhanced RTK ports
      7000-7002

      Have a good holiday weekend,

      All,

      We have implemented Ntrip/Caster support at SOPAC/CSRC
      for 29 raw data streams and 1 RTK (RTCM 2.2) data stream,
      all from Southern California (SCIGN stations
      participating in real-time subnetworks in Orange, San
      Diego, Riverside and Imperial Counties). This feature is
      newly implemented in the RTD/CommLinkProxy softwares
      licensed to Scripps by Geodetics, Inc.

      I know that most of you are familiar with NTRIP,
      developed by BKG in Germany. If not please see
      http://igs.ifag.de/index_ntrip.htm. You can download an
      Ntrip Client for various operating systems (e.g.,
      Windows,Linux,Windows CE) at
      http://igs.ifag.de/index_ntrip.htm.

      On the client, set 132.239.152.74:9031 on the
      "Broadcaster" menu and select "Update source table" to
      view the available SCIGN data, and set the flow of data
      on the "Settings" menu.

      Currently, there is no authentication (user:password)
      required. In the next few weeks, we will provide RTCM
      data streams for all these stations. Our plan is to
      support RTCM version 2.1 for the time being. Any
      comments, other than let's provide all versions of RTCM,
      CMR, etc? My preference would be RTCM version 2.3.

      On a related matter, we expect more data streams to come
      on line in the coming weeks in San Diego and Riverside
      Counties. These will be added to the Ntrip/Caster as they
      become available.

      Cheers,

      -- Yehuda
