Implement AOS Transfer Frames

[kmarwah]

Hey, I'm working with the LunaH-Map team and I'm currently working on implementing this. It should be done in a few days or so. Can you please explain the changes required in RAF._transfer_data_invoc_handler in greater detail? Thanks!

Hi @kmarwah, that's great to hear! So the last two bullet points above are referring to the same thing, the last one is just providing detail. The code in RAF here

AIT-DSN/ait/dsn/sle/raf.py

Line 337 in 9e1e0c4

tmf = frames.TMTransFrame(tm_data)

and in RCF here

AIT-DSN/ait/dsn/sle/rcf.py

Line 404 in 7fb34ea

tmf = frames.TMTransFrame(tm_data)

uses the TMTransFrame. If you will be using RAF or RCF with the AOSTransFrame instead, then you will need a way to change the frame that the _transfer_data_invoc_handler uses, or write a new handler. It may make the most sense to add a parameter to the RAF/RCF classes for the type of transfer frame to use, which defaults to TMTransFrame, and which the handler then references (@MJJoyce any thoughts on that?)

@kmarwah implemented AOS transfer frames using the Iris radio's ICD (see PR #69 for details). This implementation should be expanded to match the CCSDS's AOS spec, https://public.ccsds.org/Pubs/732x0b3e1.pdf
