We attempted to hold the Time Management teleconference as scheduled
today. Unfortunately, participation was small, some people had
conflicts, one or two may have had a daylight vs. standard time mix up,
and there was no one from outside of the U.S. joining. After a short
conversation, we decided it would be better to coordinate by email
rather than talk among such a small group.
Please respond to the following, within the next couple of days, if you can.
* If you had an input to discuss at today's meeting, please post it to
CWE in the "2020-04-06 teleconference" folder. If you do this,
please also send an email to this mailing list, with a paragraph
describing what the input is. Currently, there are two inputs
there. One is from Lee Pitts and includes his comments on the
previous Green Book draft, along with a new section, 6.2, on
ranging/Doppler. The other is from Vic Vilnrotter and includes
about 12 pages describing the time correlation concept and 3 NASA
methods for time correlation. This work is still being edited.
* Originally, we had face-to-face meetings scheduled for May 6 and 8.
Since those are now cancelled, we will schedule teleconferences. It
is not practical to meet for 8 hours in a day, given the time zones
we are in. I propose that we meet for two hours on each of May 6
and May 8, starting at 7 am Pacific Daylight Time (GMT-7). Please
let me know if this would be OK with you.
* The main goal of these meetings is to assemble a complete a draft of
the Green Book. The most important part of the Green Book at this
point is the input from each agency that describes their protocol(s)
for managing time. The introductory and boilerplate material will
be much easier to write. Please let me know your updated plans for
* Please also let me know if you have other presentations or topics to
discuss at the May teleconferences. I would like to discuss the
path forward on the mission survey of time management, for example.
Thank you for your continued participation during these trying times. I
hope you are all managing well and staying safe.
