[MOIMS-NAV-EXEC] Re: AW: Launch Data Message Concept Paper

[Oltrogge, Daniel]

Reinhard -

Thank you for your very good and open feedback - it is very much appreciated.

>From our side, this is similar to the R-15 day message that is generated by our government launch entities. That message contains some of this content, but in the past we had to augment that message because it didn't include some of the data that this proposed launch date a message contains, requiring a separate message.

Regarding the usefulness of doing launch collision avoidance, that's irrelevant on the US side because our launch agencies are required to perform launch COLA on the launch day, even for longer launch windows.

I am interested in discussing this further with you (and all) in Cleveland.  So David, can we ensure this is on the agenda?

Dear Dan,


Principally it is very desirable to have such a standard.

But in our view it makes only sense to put resources into such a project, if there are relevant launcher agencies who intend to use such a standard in the future. Might be it would be useful to involve them in such a specification process (similarly as JSpOC in case of the CDM).

Aside to this general remark we had here a first rough look to the paper and have the following preliminary comments:


-          In our view the proposed content is too comprehensive. We would prefer to keep the message as simple as possible and it should therefore be considered to put some of the information into an ICD (especially contact data among others).

-          Essential information are Separation Vector/Elements and Dispersions for each object (and some ancillary information like object properties).

-          In any way, the message should contain only data which can be generated by the launcher agency alone (and not by compiling all other staff received from various other sources into this message).

-          It is to discuss whether COLA aspects are to be included in this message. The use and feasibility of COLA screening is in our view questionable taking into account broad launch windows (up to hours) specified for a time span over several days or weeks and also including separation vector dispersions, and this for several objects.

Best regards
Reinhard

Betreff: [MOIMS-NAV-EXEC] Launch Data Message Concept Paper

All -

As we discussed in Darmstadt, here is a concept paper for the Launch Data Message (LDM)

Thanks,
