Langley" To: IGSStation@igscb.jpl.nasa.gov Subject: [IGSSTATION-1702]: UNB3: IGS L2C Test Station Modified RINEX Observation File Submissions (fwd) Message-ID: Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-igsstation Precedence: bulk ****************************************************************************** IGS Station Mail 02 Aug 06:11:46 PDT 2007 Message Number 1702 ****************************************************************************** Author: Richard Langley Rodrigo Leandro We have changed the procedure for creating and submitting RINEX 2.11 hourly and daily observation files from IGS L2C Test Network receiver UNB3 (a Trimble NetR5 which shares UNBJ's antenna) as of 30 July 2007 (doy 211) at 21 hours (GPS Time). The L2 carrier-phase measurements now come from C2 tracking rather than P2 tracking and the S2 SNR values also now relate to C2 tracking rather than P2 tracking. Additionally, there should now be no data gaps in the observation files, which previously occurred due to the previous procedure which relied on Internet data streaming to compose the RINEX files. Futhermore, files are now being delivered to CDDIS in a more timely fashion with hourly files normally having a latency of 5 minutes. Note that we also upgraded the receiver firmware on 13 July 2007 (doy 194) to version 3.32. Among other improvements, we are no longer reporting spurious observations on non-functioning GLONASS satellites. In addition to supplying hourly and daily RINEX files, this receiver also continuously streams 1 Hz data in RTCM 3.0 Ntrip format to an IGS-IP mount point hosted by BKG. =============================================================================== Richard B.
