To make sure that the needs and wishes of astro-geodetic community are integrated into the general debate, you are strongly invited to respond to this questionnaire. The four hot topics under debate are: 1. Updating the Roadmap for the redefinition of the second 2. Leap seconds in UTC - building a consensus for a continuous timescale 3. Promoting the mutual benefit of UTC and GNSS 4. Sharing resources to improve international timekeeping Questionnaire: https://www.surveymonkey.com/r/CCTF_Survey_2020 Introduction letter: https://www.bipm.org/cc/CCTF/Allowed/22nd-1/ Introduction_letter_CCTF_President_Dec_2020.pdf [please note the line wrap in this link] Your answers, opinion and ideas are very important. They will be carefully examined and taken into account by the CCTF in order to provide future guidelines and recommendations. In order to make sure that the needs and wishes of concerned institutional bodies and stakeholder communities are integrated into the general debate, we kindly ask you to answer this questionnaire before January 31, 2021.
