1. Optical Communications Green Book Outline

2. Green Books are informational, non-normative, supportive documents to blue books

3. From CCSDS Optical Communications (OPT) Working Group Concept Paper

4. Optical Communication Green Book Writing Philosophy 1.Description of parameters (terms) specified in Blue Books – Example: 2. Common Atmospheric Models recommended to support optical links selection during preparatory and hand-off planning – Utilizing measured atmospheric parameters data defined in Atmospheric Green Book 3.Links Budgets template with an example – Defining common parameters to be used for links budgets generation for various scenarios 4.Typical ConOps stages description – Coordinated with ConOps normatives specified in Blue Books

5. Details of Terminology Section –Physical Layer Terminology – Physical Layer Terminology Clock Description (Rate, Jitter, Drift) Communication Pulse (Shape,Modulation Format and Rate) Communication Pulse (Shape, Modulation Format and Rate) Optical Characteristics (wavelength,Polarization, Linewidth, etc) Optical Characteristics (wavelength, Polarization, Linewidth, etc) –Digital Domain Terminology – Digital Domain Terminology Data Rates Data Framing Coding Description Description of Interleaving Process In-band Command and TelemetryProcessing In-band Command and Telemetry Processing –Performance Metrics – Performance Metrics EIRP PFD PFD Implementation Penalties Error Rates –PAT Terminology – PAT Terminology Beacon (configuration,Spectrum, Power, Modulation) Beacon (configuration, Spectrum, Power, Modulation) Pointing (Ephemeris, Scanning) Acquisition (Spatial, Clock andFrame) Acquisition (Spatial, Clock and Frame) Tracking (Coarse, Fine) List below is notional. It will include parametersmatching those defined in Blue Books  List below is notional. It will include parameters matching those defined in Blue Books

6. Atmospheric Optical Channel Models – CFLOS Model – Atmospheric Loss Model – Turbulence Model(s) – Measured parameters defined in Atmospheric Green Book are inputs to models – Models’ outputs directly or indirectly define link budget parameters

7. Link and Pointing Budget Template – Defines common parameters to be used to construct various types of link budgets – Example from Optical Link Study Group’s (OLSG) Final Report

8. ConOps Example – Links Selection (t = t 0 – x hours) Laser Safety activities CFLOS and Atmospheric Turbulence Ephemeris Data Distribution – Links Establishment (t = t 0 – y minutes) Initialization (Pointing) Acquisition Tracking – Links Operation (t = t 0 +) Data Communication Telemetry Exchange Handover – Links termination and post operation (t = t 0 + T) Links Graceful Termination Links Performance Correlation with Atmospheric Statistics and Atmospheric Models updates Post Operation Maintenance t 0 – start of communication T – operation length
