<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
</div>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">Dear Peter,</span>
<br>
<br>
<span style="font-size:12.0pt;font-family:"Arial",sans-serif">I have read your note and I summarise my conclusions as follows:</span>
<br>
<br>
<span style="font-size:12.0pt;font-family:"Arial",sans-serif">1) It is confirmed that your original claim that the SM&C WG is improperly and unexpectedly expanding to on-board is false. It is in the WG charter, it has been since day one.</span>
<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">A charter that says "<u><span style="font-size:14.0pt;color:#1F4E79">
</span></u><u><span style="font-size:14.0pt;color:#1F4E79">E2E space-ground MO services</span></u><span style="font-size:14.0pt;color:#1F4E79"> via encapsulation/SLE tunneling, including mission planning and scheduling</span>" does not include scope for proposing
to take over responsibility for a whole host of real-time, on-board, mission critical functions on the spacecraft. Your most recent incursions included on-board power and data management. Your Oct 2016 materials (attached) show "Mission MO Services" including
AOCS, Power, Thermal, Mode Mgmt, and FDIR. These are, by all normal measures, spacecraft on-board real-time functions, SOIS territory, and no "MO functions". That chart on pg 3 is prefixed by a chart that says this:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="mso-list:l0 level1 lfo2"><b>High frequency control loops need to be implemented onboard</b><o:p></o:p></li><li class="MsoNormal" style="mso-list:l0 level1 lfo2"><b>Consequently MOIMS has always foreseen implementing services onboard as shown in the following chart 3</b><o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I believe that this is flawed logic, since there is no part of the second item that can be technically justified by the first observation. This is a situation where, while it might be possible to consider it in the scope of "what's possible",
there is no good technical justification for proposing it. It is possible, but it does not make sense.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><br>
<span style="font-size:12.0pt;font-family:"Arial",sans-serif">2) Because of its nature, mission operations are end-to-end. As such they must work with other more "local" areas of CCSDS. It is not a surprise that we have interfaces and discussion with many more
other areas than others. </span><br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">Working with "<span style="font-size:12.0pt;font-family:"Arial",sans-serif">other more "local" areas of CCSDS"
</span>is not the same as continually pushing to take over aspects of their areas of work. SEA, as I am sure you are aware, has a scope that intentionally provides oversight for all of CCSDS and we have a record of working in concert with other areas. We
have never had to take over their areas in order to accomplish this. And we have, in fact, a track record of working cooperatively with other areas.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><br>
<span style="font-size:12.0pt;font-family:"Arial",sans-serif">3) Indeed, space is not a particularly forgiving place. For exactly this reason we propose to standardise on common way of doing the same things in mission operations. I fully respect the opinion
of your experts, but please let them know that in Europe we have been doing this since 20 years with the PUS and it works.</span>
<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">Your PUS is an example of standardizing a space packet format used to send control information and return data from on-board activities. It is not in any way the same as proposing a heavyweight and complicated on-board framework for running
all of the on-board applications. We at JPL do something like PUS ourselves, as do GSFC and JSC. This is convenient, and useful, but not mandatory. And this approach of sending commands and returning data, without requiring any other integration, allows
the on-board, real-time, concerns of managing the spacecraft and its scant resources to be addressed by suitable software that is extremely well designed, well tested, and tailored for the rigors of a real-time, reliable, redundant, fault-tolerant, robust
operating environment. In this case you are proposing that this framework, which was designed for the ground, should be adopted in space when it has none of these features.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><br>
<span style="font-size:12.0pt;font-family:"Arial",sans-serif">In conclusion, the perimeter of the MO Services includes space. It is a waste of everyone's time to re-open the discussion every 6 months. You may not like it, but once decided by the CCSDS you should
accept it and work with the brief provided by our agencies. </span><br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">In conclusion, the reason why this comes up frequently is that you keep bringing it up by insisting on unilaterally trying to expand the bounds of your area. Instead of just working within the bounds of your WGs and Area you continually
mount what can politely be described as challenges to other areas. That is a key part of what I documented in my last note. If you would cease and desist in this behavior, and stick with agreed boundaries, we would not have to discuss this situation over
and over again.<o:p></o:p></p>

<span style="font-size:12.0pt">I have had to take the time to step back from your note for a moment and to look at the bigger picture. There are many threads to pull on, but let me start with the most obvious, that of the so called "London Agreement". You
seem to have been saying that the London Agreement gives the MOIMS carte blanche to push MOIMS, especially SM&C, into the spacecraft on-board environment. In point of fact the "London Agreement", as documented on pg 9 of the attached file "CESG-Report-to-CMC-Fall14-Items
attentionCMC", is all about curtailing your attempt to force MOIMS SM&C into the CSS Area. It says nothing about supporting a MOIMS SM&C incursion into the SOIS Area. That slide 9 is titled "Agreement to Resolve Cross Support and MOIMS MO Services Overlap".
That slide is all about asking MOIMS to honor the existing, and successful, CSS cross support and service management services. It says nothing what-so-ever about MOIMS being given license to expand into the spacecraft on-board domain. That concept seems
to be something that you have fabricated in your own mind relative to your memory of the "London Agreement". I think we need to keep the actual agreement, and the background leading to it, in mind.</span><o:p></o:p></p>
<p style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt">
<span style="font-size:12.0pt"> </span><o:p></o:p></p>
<p style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt">
<span style="font-size:12.0pt">In actuality, this abbreviated "agreement" that was presented to the CMC was only a small part of the story. Leading up to, and during, those London CESG meetings in 2014 there had been quite a number of discussions about all
of the aspects of the rest of CCSDS that MOIMS seemed to be ignoring the existence of. The overlap analysis file that was presented during the 2014 CESG meeting to address this problem is attached. The clear take-away message from that CESG discussion should
have been that MOIMS SM&C should be working to harmonize <b><i>with</i></b> the rest of CCSDS. It is interesting to observe you used the phrase "</span><span style="font-size:12.0pt;font-family:"Arial",sans-serif">support our desire to harmonise across CCSDS
standards … for the benefit of CCSDS and our missions". </span><span style="font-size:12.0pt">From your behavior it appears that you interpret this to mean that many of the other CCSDS areas should adopt the SM&C framework, and that your path to "harmonization"
is that they do things your way. I do not believe that the rest of CCSDS shares this opinion.</span><o:p></o:p></p>
<p style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt">

<span style="font-size:12.0pt">This may strike you as an over-blown statement, or an attack. It is not. It's really just a statement of fact. Of all of the areas it is only MOIMS and SM&C that continually pushes into the "territory" of other areas. In all
the years I have been in CCSDS I have seen no other areas do that. I note the following specific instances:</span><o:p></o:p></p>

<span style="font-size:12.0pt">I've not yet addressed the technical aspects of this, but, politics aside, those are also a consideration in determining whether any given effort is likely to result in a good outcome. One way to look at this is from the point
of view of architectural approaches, and to ask if there are antecedents that provide any means of forecasting success. There appear to be two fundamentally different technical architecture approaches that can easily be identified. I would characterize the
two approaches in this way:</span><o:p></o:p></p>

<span style="font-size:12.0pt">The first of these is the approach that the Internet has taken, and you would have to agree that it is the single most successful distributed technical architecture framework that has ever been created. It has allowed a flourishing
community of organizations and users to grow, and it has expanded in quite consistent and sometimes surprising ways to encompass new services and features. The CCSDS areas that develop protocols and interoperable services (SLS, SIS, CSS, and SEA) have followed
this model quite successfully.</span><o:p></o:p></p>

<span style="font-size:12.0pt">The second of these is exemplified in my mind by developments such as DCE, CORBA, and JMS. They all took a "framework first" approach and all have in large part failed to gain a significant foothold in distributed system. The
only "framework first" approach that I can think of that has succeeded is that of HTTP, HTML, and web services. They are ubiquitous in our world, but they are primarily examples of approach 1, layered, interoperable, protocols.</span><o:p></o:p></p>

<span style="font-size:12.0pt">The next point I feel I must make is that of assessing whether particular approaches are actually appropriate. In the Application and Support Layer (ASL) architecture description we have, as you know, been looking deeply at the
MOIMS and SOIS standards, and engaging in the intellectual exercise of trying to make this set of standards and concepts into a sort of "jig saw puzzle" that makes sense. To do that we have had to step back from "what is" and also look at "what might be".
Part of the reason for that is that there are pieces of what we understand to be typical mission operations and typical spacecraft systems that are missing. So in the conceptual, abstract, functional viewpoint we have identified functions that are part of
typical systems, but for which there are no standards at all. In the MOIMS area these are functions like operations preparation, mission data processing, on-board software management, and spacecraft development and maintenance. Just to be clear, when we
describe actual the actual standards, services, protocols, and interfaces we only describe what is, and not what might be, unless there is an identifiable plan in place. And then any of these more speculative topics are carefully labelled [Future] or [Not
planned for standardizarion].</span><o:p></o:p></p>

<p style="mso-margin-top-alt:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt">
<span style="font-size:12.0pt">We have done the same with the SOIS topics, we want this document to be comprehensive and also even handed. One of the things we have noted is that the MOIMS work tends to be expansive, it conceptually has reached out into territory
that it really has no concrete standards for. SOIS, by contrast, has been quite conservative and it only has proposed standards where it thinks that they serve a really useful, identifiable, purpose for interoperability. They even went so far as to abandon
some abstract services that had found support from one agency, but which seemed to them to be too advanced, and too abstract, to survive. One consequence of this conservative approach is that SOIS has not even tried to describe the nature of the on-board
spacecraft environment, nor the kinds of real-time concerns that are central to developing spacecraft. These are topics like the need for robustness, reliability, redundancy, fault protection, and the real-time management of precious power, thermal, data bandwidth,
data storage, and GNC / pointing resources, to say nothing of autonomous fault protection, problem isolation, and robust on-board fault recovery. All of these have been left out of the SOIS discussion, and yet all of these topics are central to designing
and developing real spacecraft. </span><o:p></o:p></p>

<span style="font-size:12.0pt">One consequence of this is that all of the diagrams that we in CCSDS have drawn, dating back at least to 2005, that have shown interactions between flight and ground leave out of the picture these key aspects of real systems.
This has turned this rich and important set of topics into a sort of "terra incognita", a blank space on the map. Without a deep awareness of the realities of spacecraft design and development it would be easy to think that this is an open field in which
to propose new approaches, because "there is nothing there". But there really is a lot there, it just happens to not be described in the CCSDS literature, largely because those who work in the field do not believe that much of it can be standardized. It
is too specialized, and too peculiar to each of our "one-off", "built for purpose" spacecraft. We surely will see some sort of "standardization by product line" in specific vendor offerings and in CubeSats, but that is different from "standards" as we tend
to use the term. I have attached a revision of a diagram from an ESA EGOS document on which I have drawn in this part of the territory and the rest of CCSDS (except for SEA and security) that was missing from the original. I did not label all of the functions,
but I just identified most of them in this paragraph.</span><o:p></o:p></p>

<span style="font-size:12.0pt">All of which brings me to my last point, that of the distinction between what we might imagine to be possible as a sort of intellectual exercise and what makes sense from a very pragmatic point of view. From an intellectual point
of view it is possible to posit that a service framework of some sort, designed to work in a terrestrial, resource rich, environment, with chatty protocols, designed for short round-trip times and lots of retransmission opportunities, and ever increasing processor
and communications bandwidth can just be expanded into space. The "IP in Space" crew had this sort of flawed logic and it has been shown to be not viable. Intellectually it is possible to posit that the whole SM&C framework, services, protocol bindings,
interaction patterns can be successfully expanded into, or even tailored for, the spacecraft on-board environment. I believe that is what led to the suggestion that SM&C could be used to do on-board power and data management, or to suggest that it could be
built into any number of different devices on-board that must function in the typical power and resource poor environment. </span><o:p></o:p></p>

<span style="font-size:12.0pt">All of the experts in spacecraft systems that I have talked to over the years, dating back to some of the earliest work I did on SOIS and even its low level services, have rejected these kinds of suggestions. They know just how
tightly they have to husband scarce resources and the care that is taken to do so reliably and robustly. To my knowledge most on-board comm interactions tend to be "fire and forget", with lost data noted in the logs, but not recovered except as a separate
retrieval operation. Most on-board management of high-speed bulk data from science instruments does not use anything that looks like a file system, instead they end to use carefully designed, reliable, robust, bulk data storage that must be specially managed,
accessed, wear leveled, etc. Access is by blocks of memory, not anything like files and directory structures. I'll grant that there are going to be some resource rich missions where some of these constraints do not hold. Some of these may accept a "veneer"
of MO services on top of what will still have to be carefully designed, managed, robust, reliable, real-time services and operating systems.</span><o:p></o:p></p>

<span style="font-size:12.0pt">I have to say that I think that CCSDS should be very careful to propose standards and approaches that make real technical sense and to avoid spending effort on things that are intellectually interesting but have little likelihood
of being broadly picked up by real space missions. I think that there is a fine line between technology that is truly visionary, like the initial concepts of TCP/IP that spawned the whole Internet-of-Things, and technology that is interesting, but just does
not have "legs" or that does not gather the support needed to thrive and survive. DCE and CORBA are examples of technologies that did not stand the test of time. It is not always easy to see these differences ahead of time, but some, like 8-track tapes,
were easy to spot. Likewise the choice between TCP/IP and DecNet, SNA, Bitnet, etc.</span><o:p></o:p></p>

<span style="font-size:12.0pt">In seeking harmonization across CCSDS and in working together for the benefit of CCSDS and all of our users we all need to keep this in mind. If, after 15 or more years of effort and proselytizing, standards do not have significant
and broad uptake by the community they are intended to serve perhaps they should be abandoned. We see that sort of significant and broad uptake in the case of SLS, SIS, CSS, SEA and even some of the MOIMS in Nav and DAI. SOIS has reinvented itself in a form
that looks like it will have legs too, with EDS and DoT, and a focus on interfaces and extensibility from a clearly defined set of core functions.</span><o:p></o:p></p>

<br>
It has been 15 years that the MO services are targeted for both ground-ground, space-ground and space-space. There are endless references for this driving design feature, I point you just to the charter of the SM&C WG (</span><a href="https://cwe.ccsds.org/fm/Lists/Charters/DispForm.aspx?ID=26"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">https://cwe.ccsds.org/fm/Lists/Charters/DispForm.aspx?ID=26</span></a><span style="font-size:12.0pt;font-family:"Arial",sans-serif">),
the published MO Services GB or the "London Agreement". We also have a published binding to SPP to cover the typical space-ground case.
<br>
<br>
It is both demotivating and disappointing that you question this. As SEA AD I feel that you should be fully aware of our long-standing approach (which we have discussed many times in the past) and instead support our desire to harmonise across CCSDS standards.
You cannot continue to put this aspect under discussion. We should all work together for the benefit of CCSDS and our missions.</span><span style="font-size:12.0pt">

<span style="font-size:12.0pt">To be completely frank, I think that you are still trying to push what are, in effect, Area Charter changes by what you are proposing. This document was intended to compare the features of the EDS and its “eco-system” and the
MAL and its eco-system, at a technical level. You seem to be asking for this document to be turned into a description of why the MO MAL should become the supported on-board environment, and that SOIS and the CCSDS on-board architecture should become fully

just reviewed that Area Charter again, which is published in the CCSDS Org & Proc Yellow Book, CCSDS A02.1-Y-4, and I do not believe that the Charter, as documented, covers spacecraft on-board services and functions. As stated in the YB, MOIMS covers the
operations of spacecraft and the utilization of spacecraft derived data, but makes absolutely no mention of spacecraft on-board applications and services. The spacecraft on-board domain is solely the province of SOIS.</span><o:p></o:p></p>

one that has been reviewed by the SOIS Area, the other members of the SEA SAWG, nor the CESG itself. I am copying this reply to the SEA SAWG and also to the SOIS AD. I expect them to reply for themselves.</span><o:p></o:p></p>

<br>
We've gone through the comments that Mehran, Mario and myself raised and have produced a consolidated output (attached). Where possible we have updated the text rather than just comment as we thought that would be more productive.<br>

What is the plan regarding updating the text in response to the list you and I worked on?<br>

to be trying to do with your requested changes to this document, which is to change the SOIS program of work and to shift CCSDS Area boundaries. Any such changes to Areas, their programs of work, and their interfaces is not handled in this way within CCSDS.
It should be handled by some sort of formal request, to the CESG as a whole and then the CMC, to make such changes. This work is being carried out in the present context and not some future one.</span><o:p></o:p></p>

<p style="margin-left:.5in"><span style="font-size:12.0pt">In the original round of reviews I very carefully extracted all of the comments from you, Mario, and others who participated, and inserted them into a spreadsheet. That spreadsheet and proposed resolutions
was then reviewed with all of the participants from the SEA SAWG, adjusted as needed, and then reviewed with the SOIS and MOIMS stakeholders. I think you got a copy of it a while ago. It has all of the identified issues and all of the proposed resolutions.
The final spreadsheet (attached here) was used to drive the edits to the document. It has inputs from you and Mario, inputs from me, and some added notes from the tech editor (KT) I had help me create the final doc. The final edited document was again reviewed
by the SAWG and the stakeholders.</span><o:p></o:p></p>

<p style="margin-left:.5in"><span style="font-size:12.0pt">With a few exceptions raised by Sam, which have since been resolved, everyone else who has reviewed this document concurs with what it says and is ready to approve it. That includes the SAWG (which
includes Roger Thompson and Ray Krosley), the SOIS crew, Sam Cooper, and Richard Melvin. At this point you appear to be the sole dissenter. And, based on your comments, you are dissenting not on the basis of technical issues with what is stated, but apparently
based on a desire to change the way that these two areas work and interact. I think that this is an inappropriate way to approach this situation and am asking you to reconsider. </span><o:p></o:p></p>

I have now finally managed to review the commented version by Sam. <br>
I compared it to the comments I had raised on the version from 07. June 2018. I have also attached that version for your reference.</span><span style="font-size:12.0pt">
</span><span style="font-size:12.0pt;font-family:"Arial",sans-serif"><br>
<br>
Some of my comments are still not implemented. I put them back in this new version of the document (it is now the third time, I am putting the same comments in the same document). I guess it would be more effective, if the author does not agree with a comment,
to leave it in and provide an answer rather than me going back each time and checking if my previously raised comments are or are not implemented.</span><span style="font-size:12.0pt">
</span><span style="font-size:12.0pt;font-family:"Arial",sans-serif"><br>
<br>
Some of the comments were implemented through the new text in red (added by Sam?).
<br>
<br>
My biggest concern is the recommendation part. I think it does make sense to align the API/Interface specification part of EDS with MAL service specification.
<br>
At least some effort shall be put in doing it for one concrete device and comparing the two XMLs.
<br>
<br>
The current document concludes, the scope is different, hence it is ok to leave everything as is and translate from one to other.
<br>
I would personally rather see two XML documents defined for one example device (e.g. a star camera with operations such as gotoMode xyz, switch on/off, ...) and a technical assessment if it makes sense or not to align the keywords of MAL and EDS.</span><span style="font-size:12.0pt">
</span><span style="font-size:12.0pt;font-family:"Arial",sans-serif"><br>
<br>
My recommendation would be that SOIS EDS remains at hardware interface definition level and delegates the specification of API/Services to be done as on-baord MO Service specifications. For this maybe MAL would need to be extended to also be able to capture
the concerns such as timing, etc.</span><span style="font-size:12.0pt"> </span><span style="font-size:12.0pt;font-family:"Arial",sans-serif"><br>
Alternatively the EDS and MAL shall be brought so much in line that the common keywords of the XML schemas are equal for the service/api specification part.</span><span style="font-size:12.0pt">

Hi Mehran. <br>
<br>
If it works for you to add your notes to Sam please do so. Maybe that will avoid addressing the same topic twice. I can sort out what we have agreed to already from whatever you add (at least I hope I can AND that it is not too cumbersome).
<br>
<br>
Please get this to me no later than CoB Thursday, 14 March. This is already long overdue.

Ciao Mario, <br>
<br>
I have Sam's inputs and we have identified acceptable resolutions for all of his concerns as of 28 Feb 19.
<br>
<br>
It's been two weeks since you asked for an extension. Is there any progress on this from your end?
<br>
<br>
Thanks, Peter <br>

Ok. Please get response to me no later than 15 March 2019. I really need to get this wrapped up. Meanwhile I will process Sam's inputs, once I have them actually in hand.

Subject: </span></b><span style="font-size:12.0pt">SEA SAWG proposed edits to the SOIS document, CCSDS 870.10-Y-1, MO Services and SOIS Electronic Data Sheets
<br>
<br>
Dear All, <br>
<br>
As reported during the CESG Telecon on 7 Feb 2019, the Systems Engineering Area (SEA), using resources of the Systems Architecture Working Group (SAWG), has completed a review of the SOIS document, CCSDS 870.10-Y-1, MO Services and SOIS Electronic Data Sheets
and proposed a set of updates to resolve differences of opinion between SOIS and MOIMS and clarify the relationships. This result was derived using meeting and email discussions within the SAWG and particularly with representatives of the two different points
of view (Roger Thompson and Ramon Krosley) and the original author of the document (Richard Melvin). Before sending this document out more widely these parties were polled and they concurred in this release, with two minor issues noted. Those issues have
been dealt with in this version. <br>
<br>
Three files are attached: <br>
1) A "clean" version with changes accepted, but revised text left in <span style="color:red">
red</span> <br>
2) A raw version with all of the tracked changes visible <br>
3) A spreadsheet extracted from the marked up PDF files, along with the audit trail of discussions leading to resolution
<br>
<br>
Since this is, in effect, a cross-area "working group" of sorts I would like to ask all of those who have a stake in this to review the document and provide feedback in two weeks, by 22 Feb 2019. I'd like to use a consensus process over email and am hoping
we can wrap this up quickly. We will still need to process the final result through the CESG for approval to publish.
<br>
<br>
Thanks, Peter </span><o:p></o:p></p>
