1.1Contractual / administrative matters
The following formal deliveries are made on the 8th of July 2003:
Architectural Design Document SS/DEBAT/ADD 1.0
Interface Control Document SS/DEBAT/ICD 1.0
Software Verification and Validation Plan SS/DEBAT/SVVP 1.0
Product Assurance Plan SS/DEBAT/PAP 1.2
Project Management Plan SS/DEBAT/PMP 1.2
The French Space market is currently going through a really difficult economic period that generates a drop in the space activities. As CS is one of the most important service providers in France, it has to face important difficulties. In spite of the crisis, CS has chosen to avoid firing people and has taken social measures so as to preserve employment, keep the staff and preserve the knowledge acquired by the company.
CS has thus decided to take a global measure to overcome this crisis. This measure consists in an overall work time reduction of 40%. It applies to all the staff of the Space Operational Centre, until the end of the year, whatever the project or the work load so as to "share" the work (this measure is made within a legal framework that impose that all staff is concerned).
Specific measures are taken for the DEBAT project to guarantee the best performance of the work within the agreed schedule:
the team is reinforced with three more persons (with a good experience of the technology),
training and integration of the new resources are taken in charge by CS.
This is a zero-cost, zero-schedule impact measure.
The current team (working since the beginning of phase 1) is as follows:
In order to cope with the work time reduction (only 60% of a full time), three more persons join the team at PDR. They are Didier Garcin, Jean-Charles Brunet and Espen Bjorntvedt (their CV's are attached at the end of this report).
Didier Garcin will work on the improved EAST core. It has a thorough knowledge of Ada and has been working on EAST for more than two years.
Jean-Charles Brunet will also work on the improved EAST core, and more specifically on the interfaces between Ada and Java (Java API, support for external functions, generation directives for the DPE and DEQ query handler).
Espen Bjorntvedt has a good experience of Java and will reinforce the team working on the new DEBAT Modeller.
They will leave the team at the end of the year.
The new team is now composed of the following persons:
Name of the person
Function within the project
Amount of time dedicated to the project (%)
Technical Manager and Responsible for Advanced Technologies
Responsible for EAST/OASIS core technologies
30% EAST (CNES)
Responsible for TM/TC activities

2Updated Schedule status
The project status is in accordance with the initial agreed schedule.
2.1Overall Gantt chart
The following chart gives the overall schedule for the whole project:
2.2Schedule from ATP to PDR
The following chart presents the updated schedule from ATP to the Preliminary Design Review: the software specifications and architectural design are completed for PDR.
2.3Schedule for the new DEBAT Data Modeller
The following chart presents the updated schedule for the implementation of the new DEBAT Data Modeller (from ATP to PDR). The first iteration of the implementation is completed.
The current section describes the work performed since the last report.
The work performed has been mainly focused on the completion of the architectural design, and on the completion of the implementation of the 1st iteration of the new Data Modeller.
3.1Software specifications and architecture design
The following table summarises the technical progress status per work-package.
WP 2200000 Software specification and Architecture Design
The implementation of the 1st iteration of the new DEBAT Modeller is completed. A demonstration of the new tool is planned for the PDR review
The following table gives the progress status for the development of the new DEBAT Data Modeller.
The following chart presents the schedule for the Detailed Design phase.
4.2Development of new DEBAT Data Modeller
The following chart presents the schedule for the implementation of the second iteration of the new Modeller tool.
5Actions follow-up list
ESA has to check if the SCOS-2000 import files (ASCII DB import files) for CryoSat can be delivered to CS
ESA has to give more information to CS about TTSIM (SCOS-2000 simulator)
Will be renamed to MCS TVT (Test & Verification Tool)
Released with SCOS-2000.
Recently modified to be able to read the SCOS-2000 import files.
Maybe DEBAT could be usefull to provide more intelligent TM/TC simulation…
CS shall document the requirements that will imply an evolution of the CCSDS norm (a kind of concept paper presenting the need/rationale and proposed implementation)
End of phase 1
CS shall take into account the comments made by A. Ciarlo on the paper version of the URD
see URD 1.01 and 1.1
The modified OASIS (integrating the type library mgt system) will be made available to the users after completion of phase 1
Technical Responsible of CS offer for Telecom Mission Centre based on the reuse of components developed for CNES project : Stentor New Services.
CS has realised the STENTOR telecommunication mission ground segment to co-ordinate and optimise the demonstration activities (booking plan), to ensure the demonstrations feasibility (energy budget, payload power level,…), and to manage the alarms and monitor the system

2001: CNES – SPOT5 Image Acquisition Loop Control
This project aims at controlling the Spot4 & Spot5 Programmation Loop, that is all the steps from the payload programming preparation to the image reception and cataloguing. The team involved 7 engineers during 1 year.
C++, Ilog Views, UNIX
2001: CNES – SPOT5 DORIS PASSENGER Management
This system has to ensure that all the requests from the DORIS Control Centre are compatible with the SPOT5 system before they are sent to the satellite, and informs the DORIS Control Centre of any event that may influence its activity. The project was realised within 3 months by a 2 engineer team.
2001-2002: Consultancy intra-Mission Centres Department for JAVA features
Architecture, audit, optimization…
1999-2000 : CNES – SPOT5/HELIOS2
Design & Development of the Satellite Technological Survey sub-system. This system implements a database archiving ancillary telemetry of the satellites during their whole life, and provides advanced means of consultation through a web interface (combination of multiple parameters, conversion from physical to logical values, calculation…), which is necessary for the Satellite Engineers to maintain them in good order.
