SUMMARY TECHNICAL STATUS
DATA COMPRESSION WG
Goal : specify an image compression algorithm fulfilling identified space mission requirements
Working Status: Active _X_ Idle ____
Summary progress:
Progress since last meeting : specification brought to a “near” red book status (spring meeting taking place may)
Problems and Issues : develop an open source reference software from source code provided by agencies : IPR issues
status: OK
CAUTION
PROBLEM
comment:
Proceeding according to charter with approx. 6 months delay

2. SPACELINK SERVICES AREA MID-TERM REPORT
OBJECTIVES OF SPRING (ON-GOING) MEETING
Finalize coding and formating details according to trade-offs results and performances analysis (only minor algorithmic features are still pending)
Review white book and update according to decisions made at meeting, with the objective of outputting red-1 within 1 month after meeting.
Review simulation softwares development status :
3 independent softwares
Check compliance with final white book
Initiate development of reference software, whose objectives are :
Enable “prospect” missions teams to evaluate CCSDS algorithm performances for real mission data
Later, to enable implementation compliance with published recommendation

CROSS-AREA TECHNICAL ISSUES
NONE
May 2004

4. SPACE LINK SERVICES AREA MID-TERM REPORT
OTHER ISSUES AND CONCERNS
Production and distribution of open source reference software for :
algorithm performance simulation
Implementation conformance verification
Will be assembled from source codes provided by various agencies
IPR issues :
should be resolved by generic software license produced by CNES in the frame of this WG.
License already used between NASA and CNES for source code exchange needed to assemble one of the simulation software presently used for algorithm development and specification cross-checking

5. SPACE LINK SERVICES AREA MID-TERM REPORT
OTHER ISSUES AND CONCERNS
Resources needed for green book production :
Objective is to output green book together with blue book
Resources availability still questionable to match this timing objectives.
