4. 07-Apr-2014-cesg-4 SLS AREA REPORT Radio Frequency and Modulation (RFM) WG – Progress Summary 1. Recommendations on high rate telemetry and PN ranging (New) RIDs to RED recommendations 2.4.22A/B received under agency review 401.0-RP-24.1 disposed of; RECs ready for CCSDS publication Accompanying draft GREEN book discussed, finalization expected in 1-2 meetings (Spring-Fall 2015) 2. Recommendations on 26 GHz modulations for EESS (New) WHITE-2 recommendation 2.4.23 discussed, RED version expected in 2 meetings (Fall 2015) 3. Recommendation on 8 GHz modulation for EESS (Update including Higher Order Modulations) Work will resume when SFCG response is received (August 2015) and in synch with 26 GHz recommendation 4. Recommendation on modulation losses due to ranging signals (Update) RIDs to PINK recommendation 4.1.5 received under agency review 401.0-RP-24.1 disposed of; additional editorial discovered; REC ready for CCSDS publication 5. 5-years review of Bandwidth-efficient modulation GB (413.0-G-2) Some additions due to new/modified RECs identified; does not make sense to start review before Spring 2016 due to on-going work 6. PCOM GB (New) Draft book discussed. Finalization was expected by Fall 2015. Only CNES has resources to continue this work and therefore CNES is against freezing this work and resuming it later. ESA withdraws monitoring role in this project  only one Agency providing resources for this project.

5. 07-Apr-2014-cesg-5 RFM WG Summary SLS AREA REPORT status:OKCAUTIONPROBLEM comment:Good progressPCOM Green Book RFM WG – Resolutions Recommendations on ranging Publish new issue of 401.0-B with - New GMSK+PN RNG recs 2.4.22A/B; - Revised rec 4.1.5. CESG position on PCOM Problem CESG consider that, if it is confirmed that only Agency works on this book, technical quality cannot be guaranteed. CMC to advise.

6. 07-Apr-2014-cesg-6 RFM WG Issue The schedule for the Spring 2015 meeting at Caltech in Pasadena (March 2015) is problematic. Both chairman and vice-chairman of the RFM WG will have to attend ITU CPM-15 meeting in Geneva. The RFM WG current focus is on GMSK+PN ranging, and on 26 GHz modulations for EESS along with VCM/ACM. The latter is a joint activity with the C&S WG. NASA has proposed to make available facilities in Pasadena for both RFM and C&S WG meetings on May 5-7. Other dates were investigated but no other solution could be found. Opposition to splitting the SLS WGs meetings has been expressed by CNES delegates. The FSA delegates stated that this is inconvenient to them but will not oppose it (attendance will depend on agendas and on visas.) DLR delegates stated that there are no problems with the May dates. CNES offered to host the meeting in Toulouse in May. This will be investigated. Additionally, the CMC meeting is planned for May 18 so there is sufficient time to report back the progress to CMC.

18. 07-Apr-2014-cesg-18 SLS-OPT: Optical Communications Working Group (1 of 5) Problem and Issues: status:OKCAUTIONPROBLEM comment:Good Progress overall, especially on the Green Book for Real-Time Weather and Atmospheric Data Blue Books Issue: NASA stated that the current plans are unacceptable. ESA/DLR considers this a change from previous agreement. SLS AREA REPORT Planning: The schedule for the Blue Books were adjusted to match the current productivity of the working group It was reported in the spring that the Working Group thought the original schedules were too optimistic. However, ESA/DLR input delivered. The Optical Communications Working Group holds monthly video teleconference meetings Planning for Spring 2015 Face-to-Face Meeting: Review of the two proposed Draft 1 Blue Books with updated technical information

19. 07-Apr-2014-cesg-19 SLS-OPT: Optical Communications Working Group (2 of 5) SLS AREA REPORT Summary of Progress: Reached an agreement that the comments on the first draft of the Green Book on Real-Time Weather and Atmospheric Data are due on 8 January 2015 DLR/IKN (Dirk Giggenbach) has agreed to be the “leader” in developing the Low Complexity On-Off Keying proposal for the Blue Books. The new schedules for the two Blue Books and two Green Books have the following dates for submission to the Area Director for approval: Green Book on Real-Time Weather and Atmospheric Data: 30 November 2015 All other books for approved CWE Projects: 28 February 2016

20. 07-Apr-2014-cesg-20 SLS-OPT: Optical Communications Working Group (3 of 5) SLS AREA REPORT OPT Blue Books Issue (chart 1 of 3): BACKGROUND: There are two Approved CWE Projects for Blue Books Optical Communications Physical Layer Blue Book, and Optical Communications Coding & Synchronization Blue Book Within each book, THREE “sections” - section 1, 2 and 3 may contain ore or more options – are expected: (1)High Data Rate (2)High Photon Efficiency (3)Low Implementation Complexity For the “High Data Rate” section two options are currently proposed a)Option 1: ESA / DLR proposal b)Option 2: NASA proposal The Working Group reached no consensus on selecting only one of those two as unique CCSDS option for the High Data Rate scenario. NASA, ESA/DLR, and CNES positions are presented in the next two slides.

21. 07-Apr-2014-cesg-21 SLS-OPT: Optical Communications Working Group (4 of 5) SLS AREA REPORT OPT Blue Books Issue (chart 2 of 3): NASA POSITION NASA stated that there should be a single “CCSDS recommendation ” for High Data Rate. Not an ESA / DLR recommendation and separate a NASA recommendation The recommendation should support space-to-space, space-to-air, and space- to-ground links NASA is willing to make changes to the NASA proposal based on technical merit so that it can become the single CCSDS recommendation. NASA also stated that acceptable options are: to release the Blue Books with only TWO sections for High Photon Efficiency and Low Implementation Complexity (i.e. without the High Data Rate section). to release TWO Blue Books: one just for High Photon Efficiency and a separate Blue Book just for Low Implementation Complexity while this issue is worked. To release TWO CCSDS Orange Books with High Data Rate a. High Data Rate with ESA / DLR proposal b. High Data Rate with NASA proposal

22. 07-Apr-2014-cesg-22 SLS-OPT: Optical Communications Working Group (5 of 5) SLS AREA REPORT OPT Blue Books Issue (chart 3 of 3): ESA/DLR POSITION ESA/DLR consider the new NASA position a major deviation from the previous agreements (IOAG, IOP-3, and CCSDS) ESA/DLR would like to stick with the Blue Book layering structure as agreed in the charter. ESA/DLR would like to create a first set of recommendations encompassing all three regimes. ESA/DLR is prepared to accept having in the Blue Books two options for the high data rate regime. CNES POSITION Ideally, CNES would like CCSDS works on a single worldwide interoperable high rate recommendation that supports the LEO-to-Earth scenario, among other scenarios.

23. 07-Apr-2014-cesg-23 RFM WGRadio Frequency & Modulation (New) Recommendation 2.4.22A/B on high rate telemetry and PN ranging ready for publication. (New) Recommendations 2.4.23 on 26 GHz modulations for EESS expected RED for Fall 2015. Recommendation 4.1.5 on modulation losses due to ranging signals ready for publication. Five years review of 413.0-G-2 Bandwidth-efficient modulation GB: to start in Spring 2016 after work on new/modified RECs finalized. PCOM GB expected by Fall 2015. However all Agencies but CNES expressed preference for freezing this work and resuming it later. Request to delay to May 2015 (before CMC) the Spring Meeting, together with C&S WG. C&S WGCoding & Synchronization Selection of new uplink codes for 231.0-B (TC Coding) confirmed, work on-going for CLTU delimitation procedures.
