Overview
Project Title	Augmenting Proximity-1 Directive Set for Lunar Operations
Approval	Approved
Document Number	211.0-B-6
Charter	5.04 Space Link Protocols Working Group
Document Type	Blue
Description of Document	Purpose – For Lunar, the CCSDS plans on defining Prox-1 directives for S-band and K-band. Lunar operations plans to add the rate 2/3 LDPC k=4096 code and OQPSK and GMSK modulations. Principles to adhere to for this change: 1. Make the directive set useable for more than just S-band (Lunar) i.e., make it multi-frequency compatible, and backward compatible with the original UHF directives in Prox-1 i.e., they will not be deleted but remain available. 2. Use Tables for frequencies and data rates (allows missions more flexibility) 3. Define a channel number index into the frequency tables … same for data rate tables 4. Front load the directive type as bit 0 instead of the last bit in the directive. (Note: we were forced to do it the wrong way by CE Mars 98 design) 5. Use one directive for SET TRANSMITTER PARAMETERS, SET RECEIVER PARAMETERS like Electra does (SET PL_EXT) but rename it: SET TRANSCEIVER PARAMETERS. 6. Replace SET PL_Extensions directive with the more generic Type 8 SPDU for Experimental Extensions for the use case where an agency has experimental orange book parameters that they would like to experiment with before they perhaps are standardized.
