Dear SLP WG,

Below please find my recommendation for our Spring 2022 SLP WG meeting to be held virtually via Webex (Invite to follow soon) on Monday May 9, 2022 starting at 7 AM PDT (16:00 CET).
I believe the meeting will last between 2 to 3 hours.

SLP WG Agenda

7:00 AM – Greetings, overview of Agenda

7:05AM – Matt Cosby will talk to the 3 technical corrigenda proposed for Annex C (Prox-1 frame to USLP mapping) in USLP (732.1-B). Goal is to gain consensus on these updates.
7:15 or 7:20 – Faramaz Devarian (NASA/JPL) will talk to his proposal for Lunar S-band Proximity Links – Goal is to understand any changes to Prox-1 Space Data Link Protocol*
8:00 or so – Greg Kazz to discuss updates to Overview of Space Comm Protocols GB (CCSDS 130.0-G-)
8:20 or so – Greg Kazz to discuss Space Packet Protocols GB – 1st edition (CCSDS 130.3-G)
Depending upon questions, comments, and concerns, anticipate the meeting closing between 9 to 9:30 AM PDT

*Minimum anticipated changes in CCSDS 211.0-B-6: Paragraphs B1.2.4, B1.4.6.4, B1.7.11,  B1.4.4 will need to be modified to account for the rate 2/3 LDPC.  Also, the Transmitter Modulation (B1.2.5) and Receiver Modulation (B1.4.5) parameters in the directives most likely will need to be changed to include GMSK and filtered OQPSK.

Best regards and look forward to hearing from you then,

Greg Kazz
CCSDS SLS_SLP WG Chair
