[MOIMS-NAV-EXEC] Diagrams and Simple Text for Nav Green Book Volume 1

[Joseph Hashmall]

Luis,


I really like your diagrams but there are a few things that I'd like to clarify.


On the first slide:

Does TM imply telemetry and does that imply telemetry from the spacecraft?  Tracking data usually comes from ground sources and I don't know if telemetry is a good description.  "Navigation Data" might be better.


On the third slide:

?The Initial Instrument Pointing may not be needed to create a PRM.  I think the essential input is the Desired Instrument Pointing.


On the fourth slide:

There are three instances in the use of the SMM.  The first instance (the Maneuver Planning Message --- MPM)
  is used when the main information that is transmitted is a description of what maneuver is desired.

The second instance (the Maneuver Design Message --- MDM)  represents the detailed design of the maneuver.  It uses the MPM as one of its inputs.

The third instance (the Maneuver Analysis Message --- MAM) represents the results of analysis of the actual maneuver results after it has been performed.  It uses the MDM as one of its inputs.


We have not yet completely decided if the three message types will be separate or if the MDM will include within it the MPM and the MAM will include within it the MAM.  This is why, in my initial crude diagrams, I showed a sort of loop in the SMM.  I don't know the best way to represent this situation in flow charts.


Thanks,


Joe?

Dear all,

you can find attached my proposal for modification of Joe's diagrams, seen from a Flowchart point of view.

For a description of the meaning of each component in the flowchart, you can visit:

All:

During today's telecon with Juan Carlos Raymond on the topic of the Nav
Green Book Volume 1, Joe Hashmall displayed some material he had prepared
that presents a more straightforward description and simple graphics than
some of the material currently in the book.  This was well received in
general.

I had the action item to send out to the group...

Regards,
David
