****************************************************************************** BSW Electronic Mail 16-Jul-1998 19:16:35 CET Message Number 0028 ****************************************************************************** Author: Markus Rothacher Subject: New IGS ERP Format Dear Bernese users, at the IGS Analysis Center Workshop in Darmstadt this year, the IGS decided to allow for one more digit in the IERS pole format. The Analysis Center Coordinator has announced (IGSMAIL #1943) that the new format will become active for GPS week 966. Therefore, those of you, who are using IGS Earth Rotation Parameter (ERP) files (final or rapid IGS products), should download a modified version of the program POLUPD, which converts various ERP formats into the Bernese internal pole file format. If you are just using pole files in the Bernese format (e.g. RAP_1998.ERP or C04_1998.ERP via our anonymous ftp), you do NOT need to change anything. Note that the IGS ERP files submitted to the IGS by CODE will change, too. The modified program POLUPD and modified subroutines are available on our anonymous ftp account: ftp ubeclu.unibe.ch userid: anonymous passwd: "your e-mail address" cd aiub$ftp cd bern40 cd source_polupd cd XXXX (where XXXX = DOS, UNIX, or VMS) The following modules are part of this update: POLUPD PGM/MAIN40/FOR modified FMTPOL LIB/GPSLIB40/FOR modified RDPOL LIB/GPSLIB40/FOR modified RDIEPI LIB/ASTLIB40/FOR new Please make a backup copy of the files mentioned above BEFORE overwriting them with the new version, so that you still have the old version available, if something goes wrong. In the case you have problems with the update, let us know and we will try to help you.
