****************************************************************************** BSW Electronic Mail 29-May-2008 12:40:02 CET Message Number 0265 ****************************************************************************** Author: Rolf Dach Subject: New CODE 5-sec clock data in Bernese 5.0 Dear BSW-users, as recently announced in IGSMAIL 5771 the CODE analysis center of the IGS generates satellite clock corrections with a sampling of 5 sec. The submission of this products has been started with GPS week 1477 (day 118 of year 2008; 27-Apr-2008). These values are useful, e.g., to process 1Hz data in a PPP mode. (Older clock corrections can be made available on request, at least for a certain interval.) This new product is accessible to the BSW users as an alternative to the traditional 30sec clock files at the following locations: ftp://ftp.unibe.ch/aiub/BSWUSER50/ORB/yyyy/ http://www.aiub.unibe.ch/download/BSWUSER50/ORB/yyyy/ CODyyddd.CLK.Z high rate (30 sec) satellite clock corrections from the CODE final IGS solution CODyyddd.CLK_05S.Z high rate ( 5 sec) satellite clock corrections from the CODE final IGS solution ftp://ftp.unibe.ch/aiub/CODE/yyyy/ http://www.aiub.unibe.ch/download/CODE/yyyy/ CODwwwwd.CLK.Z CODE final clock product, Clock RINEX format, with a sampling of 30 sec for the satellites and the reference (station) clocks and 5 minutes for all remaining station clock corrections CODwwwwd.CLK_05S.Z CODE final clock product, Clock RINEX format, with a sampling of 5 sec for the satellites and the reference (station) clocks and 5 minutes for all remaining station clock corrections To introduce these new clock corrections into the Bernese GPS Software, version 5.0, you have to increase the size for buffering the satellite clock corrections (parameter MAXEPH in ${LG}/GTSCLK.f resp. %LG%\GTSCLK.f from currently 3000 to 20000). To enable this change you have first to re-compile GTSCLK using "CLIB GTSCLK". Re-link all processing programs using "CMAIN ALL". Because most of the users -- at least from our knowledge -- do not process such high-rate data we decided to put this change NOT into the official updating schema.
