TRP Work Plan 2005-2007 Description of Activities TEC-SB/7935/dc 12/Feb/09 TRP Reference: Title: T603-28EE RCS Quiet Zone Characterization at Millimetre Wavelengths The technique has been used at ESTEC from some time and has been verified against the traditional and more cumbersome technique. What is not known is how far up in frequency the RCS technique is applicable with today's technology. While radar system are known to exist at up to 100 GHz, can the present "traditional" mode of RCS quiet zone determination be applied The question of the practical limit must be addressed in addition to the question of can a similar technique be used at higher millimetre wavelength frequencies. The application of innovative thinking is required here to be able to verify range performance where mechanism and mechanical tolerances are in the same order of magnitude as the electrical wavelength. It should be noted that in the near future the ESTEC CPTR will increase its range of operation to 100 GHz while the smaller CATR will operate up to 300 GHz, in line with present and planned Science and Earth Observation missions as well as potential use in QV band telecommunications. Deliverables: Technical note, including the way forward to characterizing antenna test facility quiet zone quality. Current TRL: TRL1 Target TRL: TRL2 Application Need/Date: TRL3 by 2008 Application/Mission: EO, Science Contract Duration: 12 months SW Clause : - Dossier0 Ref.: Consistency with Harmonisation Roadmap and Conclusions: TRP Reference: T605-01EE Title: Advanced System Level Conducted Emission Analysis and Simulation for EMC The scope of this activity is to generate a high fidelity system noise model, based on time domain equipment measurements in both differential and common mode. The exploitation of time domain measurements will improve the results of previous similar activities, reliant on frequency domain data, where the phase information was not accounted for by definition. The system complexity will be managed by breaking down of the relevant elements at the various degrees of detail available. The equivalent noise model shall encompass several features: treatment of shielded and unshielded Non Uniform Multi-conductor Transmission Lines; non-linear Components; statistical treatment of the system's uncertainties; and Signal Processing capabilities addressing noise, modulations and Power Spectral Density. The system noise model will be demonstrated against measurements on selected case studies and shall prove the ability to handle any relevant conducted emission and susceptibility. Deliverables: Technical note. System noise model.

TRP Work Plan 2005-2007 Description of Activities TEC-SB/7935/dc 12/Feb/09 TRP Reference: Title: T605-13EE Advanced System Level Radiated Noise Analysis and Simulation for EMC The objective of this activity is to create a numerical tool to simulate radiated electromagnetic field in low Q cavities and examine radiated susceptibility at unit/subsystem and system level by means of hybrid methods (full wave solvers and transmission line theory) in time and/or frequency domain. Emphasis shall be given to the representation of the electromagnetic field where the interference actually occurs, i.e. inside the spacecraft.The following features will be examined: the randomness of the system, i.e. random field from sources in a closed environment, will be treated with the stochastic treatment of Maxwell equations; characterisation of the field-to-wire-coupling onto a non-uniform multi-conductor transmission line. In order to account for the uncertainties of any complex system that lead to severe fluctuations of the electromagnetic coupling, a probabilistic approach shall be implemented. The system noise model will be validated against measurements on selected case studies.

Roadmap and Conclusions: TRP Reference: T607-10EE Title: European Antenna Modelling Component Library - Step 2 Following the successful activity on the European Antenna Modelling Library for Telecommunication applications, this activity will to continue along the path established by extending the Library to cover new requirements of by Earth Observation, Science and Telecommunication missions. Typical needs include: refinement of reflector antenna analysis tools (for very high frequency and quasi-optics instruments), innovative methods for array design (for SAR's), fast parametric modelling of small antennas (to improve speed and accuracy) and improvement of antenna interaction models (distributed antennas, out-of-band response), adaptation of modelling tools for the use as diagnostic means in AIT/AIV campaign. Furthermore, in order to reach these objective within the multi-tool environment of the Library the activity will also further consolidate the Electromagnetic Data Exchange standard. Further steps are foreseen to cover further requirements of the different type of missions not compatible with the current budget allocation and to further consolidate the most innovative developments. Electromagnetic modelling tools are a key factor in the timely and cost effective development of satellite antennas. The availability of well-established and validated tools has been proven to reduce costs and time to delivery by as much as 30%. Dedicated electromagnetic modelling tools are absolutely necessary for the successful development of European space antenna technology. Yet the expenditure in this area (about 5M over the past 10 years) has been small compared to the costs for breadboarding and mock-up testing of antennas on even a single satellite, and the potential for improvement has been exploited in a very limited way significantly reducing the benefit for European Space Industry. With direct relevance to Dossier 0 requirements, this proposal was elaborated and justified within the R&D dossier on Antenna Modelling and Tools Validation together with experts from user directorates who have approved and supported it as relevant and important for their future programmes. This action also fits the objectives of the reflector antenna harmonisation in the Telecom area. Deliverables: New antenna analysis modules for the European Antenna Modelling Library, using innovative techniques in advanced space antenna design software tools Current TRL: Target TRL: S/W Application Need/Date: SW modules operational by - modules 2008-2009 release All missions using antennas (reflector, Application/Mission: Contract Duration: 12 months arrays, TT&C and others) SW Clause : Operational SW Dossier0 Ref.: T-48 Consistency with Harmonisation Telecommunication Antennas Reflectors Roadmap and Conclusions: Page 168 of 227
