4 We see like ESA, that NMSC-SSU capabilities shall be supportive
for future developments and SatCom markets. The main questionin this context is: Who knows best about this?
4 In this context it is of highest value to ask leading edge
companies about their future plans and planned developments. These plans normally are the companies best kept secrets.
4 This consortium was (and still is) willing to share its own believes
in their futures with ESA as part of a win/win approach.
General Study Motivation of Consortium(1)
4© April 03
4 We were able to define several areas of future SatCom
developments from our own portfolios, where we are convincedto combine the best available knowledge for these comingmarkets.
4 This has lead to four different lines of important futuredevelopments, of which we believe that they are of high relevance for any NMSC-SSU.
4 We do not claim that these lines are the only ones important; butwe see ourselves as extremely competent for their assessment.
General Study Motivation of Consortium(2)

major lines of future SatCom developments
– Testing/simulation technologies for satellite terminalsand new media satcom services
– Combinations of SatCom elements with terrestrialwireless mobile communication
– Secure VPN services including generic applicationslike voice, ERP or VC
– New media services and multiservices platforms

4 As planned our study reveals several complex test, simulation and
development environments with high potentials to NMSC-SSU
capabilities.
4 As expected our phase 1 results show that such complex environments
are essential prerequisites for next generation services/ applications/
components developments.
(Remark: This position is also backed by first findings of ESA´s two
questionnaires actions as presented on workshop in February 2003)
Phase 1 Report: General Results (1)

4 It is evident that such complex simulation/ development/ testbed
environments cannot be seperated from considerable human expertiseand thus cannot easily be transferred to other places or organisations.
4 This means for ESA´s NMSC-SSU plans, that important capabilities of this
kind can only be found in places with considerable experience and „heritage“.
4 Therefore NMSC- SSU capabilities (except minor support features)
will mostly be distributed.
Phase 1 Report: General Results (2)

4 We also have identified within our own consortium quite strong
similarities between two different partners (FOKUS.SatCom and IABG)
4 We regard this as a positive example for our position to allow and evensupport competition, because it raizes the chances to open these
complex labs to others from outside in cases of restrictions frompartnerships.
4 We strongly recommend to ESA to identify more alternative competence
centers all over Europe.
Phase 1 Report: General Results (3)
9© April 03
4 Major capabilities exist and should be made available to European
industry and research.
4 ESA should identify all those capabilities and try to find a structural
approach for describing and categorising these capabilities in terms of:
- HW/ SW/ Infrastructure (as initialized in heritage questionnaire)
and:
- related human experiences/ projects/ partnerships
in order to find an overview information base for matching new
users´requirements with existing European capabilities
General Conclusions for NMSC-SSU (1)
10© April 03
4 ESA´s role in this context therefore should more or less be
restricted to provide or to organize:
- an open capabilities description platform including the related
(human) competencies and
- some user support services like module libraries or basic
functionalities
- a regular update of ist users´and heritage questionnaires in a
workshop centred dialogue with interested partners from Europe
General Conclusions for NMSC-SSU (2)
11© April 03
4 ESA should contribute to further development of existingcomplex capabilities (competence centers) by:
- (co-)funding technical opening of existing lab environments forexternal access and towards open standards („ESA- certificate“)
- identifying (by permanent matching of users´ demands and actual competence centers´heritages) current deficits and (co-) funding (with regular competitive bids) the necessary
improvements and
- (co-) funding of usage by research and SMEs.

Fraunhofer FOKUS CC TIP – Know-how in Test System Development and Software Support
Testing and Test Control Notation4 new version of the only standardized test
notation (ISO/IEC 9646-3, ITU-T X.292)4 developed by ETSI TC MTS (STF 133 & STF
156)4 suitable for Testing of/related to
– conformance, interoperability, robustness, performance, regression, integration, etc.
4 main features comprises:– Dynamic concurrent testing
configurations – Encoding information and other
attributes (including user extensibility) – Optional presentation formats (tabular
and graphical) – Test suite and test system control.
4 has been applied to e.g.– mobile communications
(GSM, 3G, TETRA), – wireless LANs (Hiperlan/2), – cordless phones (DECT), – broadband technologies (B-
ISDN, ATM), – CORBA-based platforms– internet protocols such as
IPv6, SIGTRAN, SIP and OSP.

DVB-RCS Simulation Unit
4 Main component of the proposed DVB-RCS simulation unit will be ahardware platform controlled by a ”Simulation Tool”
4 The ”Simulation Tool” will be composed of:
• Script Tool• Basic Functions
4 Basic Functions are software tools, which represent general DVB-RCSfunctionalities. They should support the user with:
• Results (e.g. protocol traces, CMT values) on demand• Parameters to control the behaviour of the Hardware platform
4 NDSatCom in cooperation with CETECOM are prepared to implementthis DVB-RCS Simulation Unit

DVB-RCS Testing Unit
4 The infrastructure used for DVB-RCS simulation unit is an excellent basis for a Satellite Terminal test bed
4 Software and hardware used for DVB-RCS simulation could be reusedto a large extend for satellite terminal tests
4 Basis for test scenarios shall be the output of the ”Feasibility Study”initiated by ESTEC and performed by CETECOM
4 NDSatCom in cooperation with CETECOM are prepared to implementthis DVB-RCS Testing Unit
