Subject: | [SLR-Mail] No.2147: Results from 2012 Leap Second Survey | |
Author: | ILRS CB | |
Content: | Author: ILRS CB/Randall Ricklefs, Carey Noll Dear Colleagues, As many of you are aware, the ILRS handling of the leap second last June 30/July 1, 2012 could have been smoother. The ILRS CB has been learning the magnitude of the problems and working on solutions. The result is the attached document, which outlines specific steps to make the next leap second transition smoother. Most of these involve proper implementation of the CPF leap second flag by predictions providers and stations. The document is also available on the ILRS website at: http://ilrs.gsfc.nasa.gov/docs/2012/leapsecond_2012.pdf We look forward of the participation of the ILRS stations, prediction providers, and analysts to make the next leap second insertion problem-free!
