[IGSMAIL-8274] Reminder about the upcoming switch of the IGS to IGS20/igs20.atx and repro3 standards [SEC=OFFICIAL]

[Salim Masoumi]

Dear Colleagues,

This is a kindly reminder about the upcoming switch of the IGS products to IGS20/igs20.atx and repro3 standards as described in [IGSMAIL-8238]<https://lists.igs.org/pipermail/igsmail/2022/008234.html> and [IGSMAIL-8256]<https://lists.igs.org/pipermail/igsmail/2022/008252.html> starting from GPS week 2238, 27 November 2022. In addition to the weekly final products, rapid and ultra-rapid products aligned with IGS20 and with long filenames are now also available for testing. You can find the test products at:

-        CDDIS: https://cddis.nasa.gov/archive/gnss/products/${wwww}/igs20/<https://cddis.nasa.gov/archive/gnss/products/$%7bwwww%7d/igs20/>

-        IGN: ftp://igs-rf.ign.fr/pub/igs20_tests/${wwww}/
where ${wwww} refers to GPS week. Please note that rapid and ultra-rapid long filename products are only for testing purposes until the date of the switch on 27 November 2022.

Attached is a document outlining the changes to the filenames. Please note this document may be updated with future versions to include the most recent changes and/or more complete descriptions.

Please also note that starting from GPS week 2238 (27 November 2022), the IGS final, rapid and ultra-rapid products will be available only in long filenames. Starting from GPS week 2238, the new files with long filenames will be in normal locations in the data centres, e.g.:

-        CDDIS: https://cddis.nasa.gov/archive/gnss/products/${wwww}/<https://cddis.nasa.gov/archive/gnss/products/$%7bwwww%7d/>

-        IGN: ftp://igs.ign.fr/pub/igs/products/${wwww}/

-        BKG: ftp://igs-ftp.bkg.bund.de:/IGS/products/${wwww}/
