The changes were agreed by CMC already. Please have the charter status 
changed to "approved".

Additionally, note that the goals on the charter and the ones in the 
relevant project (
http://cwe.ccsds.org/fm/Lists/Projects/DispForm.aspx?ID=126&Source=http%3A%2F%2Fcwe%2Eccsds%2Eorg%2Ffm%2FLists%2FCharters%2FDispForm%2Easpx%3FID%3D31
) are not the same. The text currenttly in the charter under approval 
shall replace what is in the project. I tried to simply copy and paste but 
got large number of control characters.

CHARTER:

Goals
The goals of this Working Group are to: 

1) Develop modulation recommendations for 22 (the band near 22 GHz), 26 
and 32 GHz high rate links; 

2) Develop recommendations for Lunar missions to operate at 2 GHz with 
other users; 

3) Revise the recommended schemes in 2.4.17A and develop necessary 
companion recommendations on imbalances and other impairments; 

4) Update 413.0-G-1 in line with recent changes to 401.0-B-16 and move 
normative text from 413 to 401 (as attachments to 2.4.17A, 2.4.17B and 
2.4.18); 

5) Update the RF and Modulation Book CCSDS 401.0-B-16 set of 
recommendations on modulation techniques as per items 1 to 4 above and 
possible changes required by technical or regulatory issues; 

6) Review the RF and Modulation Compatibility Test Procedures Book CCSDS 
412.0-G-1 and update it if necessary; 

7) Study future Earth Exploration-Satellite-Service requirements in terms 
of modulation schemes with signaling efficiency better than the schemes in 
recommendation 401 (2.4.18) for the 8025-8400 MHz band and possibly the 
25.5-27.0 GHz band, and study performance of the advanced modulation 
schemes proposed by the coding and synchronization WG; 

8) Study efficient way to combine high rate telemetry and PN ranging with 
suppressed carrier modulations for the space research service bands; 

9) Study the NGU requirements for file uploading and as a consequence 
update recommendation 2.2.8; 

10) Study the NGU requirements for MSPA support and as a consequence 
develop flexible turn-around ratios recommendations for the 7/8, 34/32 and 
40/37 GHz bands or an alternative technique to provide MSPA (multi-carrier 
operations, CDMA, etc.); 

11) Study impairments for 4D-8PSK TCM and propose relevant 
recommendations; 

12)Review the Proximity-1 Blue and Green Books and propose changes if 
needed; 

13) Perform 5-years review of 413.0-G-2 and update it as needed; 

14) Co-operate with SLS-C&S for ACM/VCM techniques for the 26 GHz EESS 
channel; 

15) Study turn-around ratios for the new EESS uplink allocation at 7 GHz 
in association with the 8 GHz downlink and propose relevant 
recommendation; 

16) Propose changes to DDOR recommendation 2.5.6B for low cost missions; 

17) Study telemetry ranging concept and propose relevant recommendation; 

18) Study modulation technique and position for pilots symbols of high 
order modulations used in conjunction with the codes of CCSDS 131.0-B-2. 

PROJECT:

Description of Document
Recommendations for Radio Frequency and Modulation Systems, Part 1, focus 
upon the standardization of RF and modulation systems for Earth stations 
and spacecraft.  These Recommendations do not provide specific designs. 
Rather they describe certain capabilities and provide technical 
characteristics in sufficient detail so that an agency may design 
compatible equipment.  Guidelines are also provided for the use of 
agencies’ RF and modulation systems, as well as their use of the RF 
spectrum. Because an ability to provide cross support implies some 
standardization of design and operations, certain procedural 
Recommendations have been included to assist in these areas. 
Recommendations are assigned to one of three sections depending upon 
whether their primary focus is technical, policy, or procedural in 
nature.  These Recommendations are intended to promote an orderly 
transition to RF and modulation systems that are internationally 
compatible. The CCSDS believes that this course will not only assure 
better engineering practices but, also, that it will facilitate 
international cross support agreements.  These recommendations are 
gathered in CCSDS document 401.0-B. This blue book is regualry updated and 
complemented by the RF & Modulation WG to either incorporate new 
recommendations (e.g. : modulation types for new frequency bands), or to 
reflect evolving techniques for existing frequency bands and mission 
types.  More specifically, the following evolutions are now being tackled 
by the WG : 
1) Develop modulation recommendations for 22 (the band near 22 GHz), 26 
and 32 GHz high rate links; 
2) Develop recommendations for Lunar missions or missions supported by 
data relay satellites to operate at 2 GHz with other users; 
3) Revise the recommended schemes in 2.4.17A and develop necessary 
companion recommendations on imbalances and other impairments; 
4) Update 413.0-G-1 in line with recent changes to 401.0-B-16 and move 
normative text from 413 to 401 (as attachments to 2.4.17A, 2.4.17B and 
2.4.18); 
5) Update the RF and Modulation Book CCSDS 401.0-B-16 set of 
recommendations on modulation techniques as per items 1 to 4 above and 
possible changes from SFCG-26, SFCG-27 and WRC-07; 
6) Review the RF and Modulation Compatibility Test Procedures Book CCSDS 
412.0-G-1 and update it if necessary; 
7) Study future Earth Exploration-Satellite-Service requirements in terms 
of modulation schemes with signaling efficiency better than the schemes in 
recommendation 401 (2.4.18) for the 8025-8400 MHz band and possibly the 
25.5-27.0 GHz band, and study performance of the advanced modulation 
schemes proposed by the coding and synchronization WG; 
8) Study efficient way to combine high rate telemetry and PN ranging with 
suppressed carrier modulations for the space research service bands; 
9) Study requirements for communications resulting from emergency 
conditions; 
10) Study requirements for future very high rate deep space communications 
and develop higher-order modulations recommendation; 
11) Study the NGU requirements for file uploading and as a consequence 
update recommendation 2.2.8; 
12) Study the NGU requirements for MSPA support and as a consequence 
develop flexible turn-around ratios; recommendations for the 7/8, 34/32 
and 40/37 GHz bands or an alternative technique to provide MSPA 
(multi-carrier operations, CDMA, etc.); 
13) Study impairments for 4D-8PSK TCM and propose relevant 
recommendations; 
14) Review the Proximity-1 Blue and Green Books and propose changes if 
needed; 
15) Produce a Planetary Communications System Green Book; 
16) Co-operate with SLS-C&S for ACM/VCM techniques for the 26 GHz EESS 
channel. 

NOTE: This final edition of the RF&Modulation systems blue book will 
include : 8PSK, 16-APSK, 32-APSK and 64-APSK modulations, Blue 
recommendation on 22 (the band near 22 GHz), 26 GHz modulation, Blue 
recommendation on 2 GHz modulation missions supported by data.
