[cssm] Fw: DDOR configuration template

Tue May 26 14:25:06 UTC 2020

Hello

I am already in a Telecon at that time.
I will join you after 17h00 European time to cover the DDOR agedna item.

Regards

Dear Martin,

Now that I finally have a copy of what you sent to Colin, of course, I 
have some comments :-)

First, the instance document is not quite proper XML -- at least as Oxygen 
on this end looks at it. Please see the screenshot below. Attached is what 
I believe to be a properly formed version of the instance document. 

To set the context, as I recall, the basic question was whether or not we 
needed to look at another standard or augmentation to the SMURF to 
accommodate the interagency ground sequence for conducting a DDOR 
observation. I think the answer tends to be yes to the general question 
here. Presumably the spacecraft event sequence will cover when DOR tones 
are on/off but then of course there is the scan pattern and that has to be 
coordinated between multiple agencies. I think the instance you have 
submitted is a step in the right direction.  Here are some comments, 
questions, observations:

1.      It seems like this is something of a cross between a template and 
a fully stated instance. For each of the targets to be in the scan 
pattern, there appears to be a presumption that the scan will start at BOT 
plus the delay. Is it fair to assume that the DDOR supports for a mission 
will always fit this kind of pattern?  I suspect the answer is no and that 
there are either multiple patterns.  At a minimum, depending upon whether 
the groundstation is the "incoming" groundstation with regard to 
communications geometry or the "outgoing" groundstation then this would 
probably also have to have something that is stated as the offset relative 
to the EOT? Or perhaps we should think about allowing absolute times to be 
stated?
2.      Recevier_2 -- this seems like an internal concern to the 
implementation -- I think for international standard the main thing would 
be to have the scan pattern identified and not which particular 
(open-loop) receiver is being used.
3.      Given that DDOR requires a fair amount of interagency coordination 
and there are constraints with regard to communication geometries and 
quasar of visibility, should there be some sort of provision for 
indicating the ground stations involved in this? I'm not sure that this is 
really needed but then again it does seem like if we are doing this 
interagency the data standard has to allow for being very precise and 
clear as to the exact apertures being requested to support the scan 
pattern -- that of course could be indicated in the aperture constraints 
of the SMURF.

Assuming you can attend our teleconference on May 26, I look forward to 
discussing this further.

Best regards,
-Erik

Hello

I have drafted a proposal of xml layout for DDOR support based on our 
experience on ESTRACK 

This need to be tune to the SMURF, but all the element of information 
shall be there. 

>From our operational experience, using the formulare in the magenta leave 
room to build invalid contradicting entries. 
And it did happen many time. 

This minimum set of value, together with the element contain in the SMURF 
request could be used to write the old text format in the magenta book 
(see below) to support backward compatibility if needed. 

For memory
