[Sls-slp] Updated Prox-1 Link Directives for Lunar Operations

[Kazz, Greg (US 312B)]

Hi All,

Yet another update with the new type 3 SPDU format this time with a diagram showing the directive fields and bit layout.
I will store it on the SLP WG CWE as well.
To be discussed at the Spring (May) SLP WG meeting.
Please comment.

Thanks much,
Greg

Subject: Updated Prox-1 Link Directives for Lunar Operations

Dear SLP WG,

Attached is the latest thinking towards Lunar Interoperability beyond the first Lunar Pathfinder Mission.
It contains a new “type 3” variable length SPDU as a “composite” directive for Link Establishment, maintenance (moving to working channel) and Status needs. It is still a work in Progress.
Please take a look. Stuart Golden of Vulcan Wireless will present this approach in more detail at our Spring 2023 May meeting in Huntsville, AL USA.

Please let me know if you have any questions.

Stay curious,
Greg
