[MOIMS-NAV-EXEC] Fw: ESA Review of CCSDS 502.0-P-2.1. Orbit Data Messages - reminder

[Frank.Dreger at esa.int]

Dear David, dear Dan,

concerning the one ESA RID on grouping parameters I have received the 
following clarification from the author Cèlia Yábar Vallès:

I checked a bit on the parameters grouping that we proposed and I also 
discussed it with the colleague who mostly had the idea. The idea of this 
comment was to ensure some consistency when sending out some groups of 
parameters. Since the data can be exchanged between machines, the concept 
could be to emulate some human logic when sending out groups of 
parameters.

With functional grouping, what we meant, for example was, on a simple 
example: you have the S/C MoI which are 6 elements, so all of them need to 
be filled up and be in the same group. You could also have the mass and 
other parameters related to that, which need to be coherent with each 
other. Or another example, if you provide the drag or the solar radiation 
pressure coefficient you also need to group it with for example the drag 
or the SRP area. 


Kind regards
