Project Title

Add New Normative Annex: Proximity-1 Link Default Session Access Control Parameters for the Mars and Lunar Enterprises



Document Number



5.04 Space Link Protocols Working Group

Document Type


Description of Document

This new normative annex defines specific default communication parameters that details the protocol option space for specific Enterprises. It specifically defines the default proximity session communication parameters for proximity-1 SDLP; Session Establishment (currently achieved via Hailing) and Moving onto a Working Channel. It will document the de-facto the Prox-1 default link Establishment and Working Channel parameter values used at Mars and document the emerging default Link Establishment and Working Channel parameters for Lunar
