I have seen that your skeletons can be downloaded now via FTP. Please note that skeletons from other sources are made available via HTTP. Examples for HTTP links (see i.e. sourcetable from http://www.igs-ip.net) are: http://igscb.jpl.nasa.gov:80/igscb/station/general/skel (IGS) http://igs.bkg.bund.de:80/root_ftp/NTRIP/station/rnxskl (Miscellaneous IGS) http://www.epncb.oma.be:80/stations/log/skl (EUREF) http://igs.bkg.bund.de:80/root_ftp/GREF/station/rnxskl (German GREF) The problem now is that the BNC (I don't know about other tools which download skeletons) expects an HTTP link for the skeleton files in data field # 7 of the sourcetable's NET record. So far it can not deal with FTP links. Hence my question is: - Would it be possible to make your skeletons (also?) available via HTTP? Best regards, Georg PS: Your sourcetable http://192.104.43.25:2101 mentions networks AuScope-WA, ARGN, AuScope-SA, AuScope-VIC and AuScope-TAS. My suggestion would be that you introduce a NET record for all these five networks. The logic is that a specific NET record is required for each "net" mentioned in the STR records. Data field # 7 of the NET records may then contain a HTTP link to the skeletons files of stations which are part of this network. Once you have done this, whoever converts streams to RINEX using BNC and your caster gets a complete and up to date RINEX header. (You may delete your NET record "IGS" as long as non of your STR records mentions "IGS" in data field # 8.) -----Urspr|ngliche Nachricht----- Von: Michael.Moore@ga.gov.au [mailto:Michael.Moore@ga.gov.au] Gesendet: Donnerstag, 17.

The following stations belong to the AuScope Network: ALBY BBOO BDLE BEEC BURA ESPA HYDN KALG KELN KUNU LIAW LORA NORS PTLD SA45 SPBY YEEL YELO We intend to keep the real-time streams obtained from the ARGN network freely available for scientific use. Those stations which belong to the AuScope network will be freely available for scientific use until the end of 2009. We hope to be able to keep these streams available for free for scientific purposes, but cannot guarantee their availability until after data agreements have been finalised. The AuScope stations list will be growing significantly over the next two years, please refer to the source table on the NTRIP Caster as to which network the stations belong to. Regards, Michael Moore
