SLS-RFM WG summary • Review of 401 in light of WRC-03 and SFCG-23 results in following progress: • 23 recommendations were editorially reviewed and approved by WG for 401 editorial update  RFM WG resolves to submit editorially updated recommendations to CCSDS Editor via SLS AD for incorporation into 401; • Revised recommendation 2.4.10 (channel input and coding conventions for QPSK systems) was approved  RFM WG resolves to submit RED recommendation 2.4.10 for Agency Review via SLS AD; • Work on a number of other recommendations (2.4.11, 2.3.3A/B, 2.3.4A/B, 3.1.2B, 2.1.3B, 2.1.4B, 2.1.7B, 2.3.2, 2.3.5, 3.3.3A, 2.4.14B, 2.5.1B, 2.6.12, 2.4.19, 2.4.12A/B) is progressing well so that charter milestone (Nov 2004 - Propose updates of CCSDS 401.0-B recommendations on modulations)is expected to be met; • Errors introduced by Editor in two recommendations of 401-B14 (2.2.8 and 2.5.6B) were detected (2.2.8 already with Editor).

  3. SLS-RFM WG summary • Problems report: • Only problem is with status of recommendation 2.4.18 (see separate presentation). • Future work/charter: • Future work continues as per charter – no changes/delays foreseen • SCCC-8PSK (along with APSK modulations) proposed by ESA in Paris will be presented also in Montreal to the coding experts: • Evaluation of ESA proposal by other Agencies is planned for Spring 2005; • Preliminary results of hardware tests foreseen for Spring 2005; • Joint Coding and RF&Modulation meeting expected to be needed in Spring 2005. • DVB-S2 ETSI standard proposed by CNES shall follow same route as ESA’s proposal.

  4. SLS-RNG WG summary • Work in progress on following milestones: • Review of requirements in navigation/ranging performances of future missions; • Review of techniques available to meet the requirements, e.g. regenerative ranging, Delta-DOR, high frequency ranging; • Results to date: • Requirements review is on going (first iteration completed); • Revised recommendation 2.5.6B (Delta-DOR) was approved  RNG WG resolves to submit RED recommendation 2.5.6B for Agency Review; • Work on regenerative (PN code) ranging is progressing at fast pace: four candidate codes were presented; • Number of actions was taken to try and complete analysis of the four presented codes with timeline as per charter.

  5. SLS-RNG WG summary • Problems report: • None • Future work/charter: • Future work continues as per charter – no changes/delays foreseen.
