Overview
Project Title	Proximity-1 extension
Approval	Approved
Document Number	211.2-B
Charter	5.02 Space Link Coding and Synchronization Working Group
Document Type	Blue
Description of Document	The blue book, with respect the current issue will include high rate coding (greater than 0.5) to further conserve the bandwidth. This update is done in parallel to the update of 211.0-B and 211.2-B blue books, that will be done by SLS-SLP and SLS-RFM for including the followings: - S-Band 2025-2110 MHz and 2200-2290 MHz for covering forward (orbit-to-surface) and return (surface-to-orbit) Lunar allocations, possibly extended as 2025-2120 MHz and 2200-2300 MHz for covering also Martian (orbit-to-surface, surface-to-orbit, orbit-to-orbit) allocations; - Possibly other frequency ranges in K-Band (22/27 GHz) for covering other allocations in the Lunar and Martian regions; - Bit rates higher than 2048 kbps; - Spectrally-efficient waveforms to conserve bandwidth, - High rate coding (greater than 0.5), to further conserve bandwidth; - Use Version 4 transfer frame format for added flexibility; - Space Link Protocol adaptations for the new features (e.g., the SET PL EXTENSION).
