Deadline for abstract submission is 1st February 2010. http://www.congrex.nl/10A07/ The Communications-TT&C Systems and Techniques Section of the Directorate of Technical and Quality Management is pleased to announce the Fifth Workshop on Tracking, Telemetry and Command Systems for Ground and Space Applications, TTC 2010, which will be held from the 21st to the 23rd of September 2010 at the European Space Technology Centre (ESTEC) in Noordwijk, The Netherlands. Tracking, Telemetry and Command systems are of fundamental importance in the space programmes. Recent developments in the areas of telecommunications, signal processing, computing and electronics provide new capabilities in the design and functionality of TTC systems either in space or in ground systems. New frequency bands will be used for TTC applications in the future. Their adequate exploitation will be fundamental for innovation and for driving forward the next generation of TTC links in order to support the demanding communications requirements of future manned and unmanned missions. Deep space missions are evolving and the applications required place demanding requirements and challenges on the TTC system design. Methods and architectures for the handling of TTC components and their interconnection are also evolving and will cause the space systems to be closer to the community of users. Alongside with the workshop, an industrial exhibition will be organized. European companies active in the TTC area will be invited to exhibit samples of their products either by mean of equipment demonstrations or by appropriate posters. The workshop will focus on TTC applications, TTC technology, TTC trends and TTC requirements for both ground based and space based equipment's, with the aim of fostering exchanges between the people involved in the research and industrial development. Contributions from European and non-European companies, organisations, universities and institutions are solicited. OBJECTIVES OF THE TTC 2010 WORKSHOP The aim of the TTC 2010 Workshop is to assemble an international forum where TTC equipment designers, systems developers, added value system suppliers, operators, experts, universities and space agencies can openly discuss their ideas, share their experiences and formulate challenges to be met. The workshop will offer an overview of the technologies in use or in development. Hence, it will be a suitable forum for identifying trends in the requirements, architectures and technologies to be given attention during the coming years. Participants will have the opportunity to share their technical expertise and views by formal presentations, informal discussions and round tables leading to: Explore innovative approaches and new technology trends in the area of TTC that will permit to satisfy the needs of future space programmes Identify potential areas for cross-fertilisation between the different space programmes, taking also benefit of synergies between commercial and scientific applications Best regards Jean-Luc Gerner TEC-ET Tel: +31 71 565 4473 From greg.j.kazz at jpl.nasa.gov Thu Feb 11 18:25:50 2010 From: greg.j.kazz at jpl.nasa.gov (Kazz, Greg J (313B)) Date: Thu, 11 Feb 2010 10:25:50 -0800 Subject: [Sls-slp] Maximum Frame size for Turbocodes?

A NASA mission in pre-phase A has approached me to ask if CCSDS has completed any further studies per the comment in the current standard below to allow missions to use the 2048 octet frame size. Have any further studies been carried out or are planned by CCSDS ? Currently Section 8 of the TM Sync and Channel Coding (CCSDS 131.0-B-1 ) states: 8.6.2 Performance for only the following information block lengths (i.e., Transfer Frame lengths) has been validated by CCSDS and approved for use (values are in octets): a) 223; b) 446; c) 892; d) 1115; e) 2048. NOTE - Interleaver parameters for the length 2048 octets are under study by the CCSDS. Until finalized, use of this option is not recommended. Looking over the pink sheets (ccsds 131.0-P-1.1) I did not see any new information on this section.

I hope the same applies to other Agencies represented in the C&S WG. Unfortunately I cannot give you a consolidated position yet. I can however give you a couple of preliminary comments on the input paper. In the following sentence there is a mistake: Several NASA Programs i.e., Program Constellation and the Mars Program are requiring the use of LDPC codes for their Proximity Links: �� Constellation rendezvous links (e.g., Orion-ISS) �� MSL to MRO link at Mars (2011) �� LDCM (Landsat Data Continuity Mission, 2013) �� GOES (Geostationary Operational Environmental Satellite, 2015) Obviously, LDCM and GOES do not have proximity links. The LDPC codes have been selected for their 'normal' EESS (Earth Exploration Satellite Service) data downlink to Earth. The White Paper mentions MSL Electra for LDPCC addition, but it would be very interesting to know which kind of backward compatibility is included in Electra upgrade with LDPCC. I am sure that this information will be very valuable for those missions that will stick to the former Proxi-1 coding for missions flying or under (frozen) development.
