NILU

At NILU - Norwegian Institute for Air Research, each scientist has a workstation (Windows, Mac or Linux). Both the IT group and the NILU scientists have knowledge on, and are highly capable in, but not limited to, Python, Perl, R, MatLab, IDL, .Net. C/C++/C sharp.
NILU has a modern machine park with all necessary software and hardware facilities and a separate IT division taking care of the daily operations, including backup. Our hardware machine park consists of both physical and virtual machines, and there is a medium size computable Linux cluster with about 300 CPUs including a large disc storage capacity. The machine park and its data is in-house, with backup to an external location every night. NILU also has cloud storage facilities.
NILU has meeting rooms for 8-40 people with teleconference facilities and the ability to host workshops, meetings and conferences. There is also an in-house library and journal access, as well as support services such as design resources, communications team and a financial and human resource management department.

NILU has its own comprehensive library which will be used by 3DCATS to access relevant literature.

Furthermore, NILU’s scientists are supported by an administrative and financial department, familiar with ESA projects.


UNILEON
The present study does not require unconventional or complex facilities. The Concurrent Design Facility of ULE shall host the management office, using in-house dedicated tools to coordinate/trace the requirements of scenarios, users and missions and systems in a way easily accessible and shareable among partners and ESA.

Other facilities available for the ULE Aerospace Research group to develop the present project include:

Concurrent Design Facility: pool of 12 high-end computers equipped with state-of-the-art software packages and coordination tools, shared visualization and communication assets and a co-located meeting room. The software licenses include last versions in the following areas/suppliers:

• 
  Image processing: ENVI/IDL (Harris)
  
• 
  Modtran: Atmospheric model (SSI)
  
• 
  CFD: Fluent (Ansys), X-Flow (Next Limit) and OpenFoam (open)
  
• 
  Mechanics: Mech solver (Ansys), DesignModeler (Ansys), DesignXplorer (Ansys)
  
• 
  CAD: Catia (Dassault), Autocad (Autodesk), Inventor (Autodesk)
  
• 
  Modelling: MATLAB and SIMULINK (Matlab)
  
• 
  Management: MS Project (Microsoft) and Requirement Management Tool (in-house)
  
• 
  Statistical analysis: SPSS (IBM)
  
• 
  Offimatics: MS Office and MS Visio
  

High-performance Processing Centre: ULE hosts SCAYLE, the regional supercomputing facility (www.fcsc.es), providing high capacity for researchers: up to 4000 processing cores. Besides. The aerospace lab owns a Centos-based HPC with three cards 40 cores each.

Workbench rooms: the Aerospace Group develops its activity in a research-dedicated building where propulsion, avionics and manufacturing testbenchs are installed in an area of about 400 m². Top-quality 3D printer areas (including metal capable) are also available.

The utilisation of the available processing power and storage and the software licenses provides straightaway methods to simulate new products, to assess performance and to validate concepts.

The facilities also include a meeting/videoconference room with very high rate internet access and Webex and Skype accounts.

Regarding information resources, ULE maintains subscriptions to main aerospace research journals, including AIAA, IEEE and European titles.
Thales Alenia Space (TAS)

TAS general experience covers many domains from telecommunications, earth observation, science and exploration, navigation to advanced electronics with adequate commercial and marketing services to ensure the associated business plans. Also the ‘Space Alliance’ venture with Telespazio allows offering a complete range of services and solutions, from equipment to end-to-end systems. The Space Alliance has a unique potential to move into vertical markets, spanning the entire value chain from conception and fabrication to operations and services. TAS with 15 sites in Europe has a strong industrial presence and can propose a big infrastructure to contribute to the study and furthermore to a potential demonstration project. In particular, the infrastructure for the StratobusTM project has already been studied and inflatable hangars are being analysis for AIT and maintenance activities.

DEIMOS Mission Analysis and Flight Mechanics Simulation Tools
In ESA projects for technology development or for supporting feasibility studies, budget limitations impose the application of suitable strategies to cut down the cost of new developments, concentrating on the engineering solution being the core objective of the project. In this perspective, in order to approach challenging projects involving ambitious algorithms and SW development, DEIMOS has developed a set of SW products as either internal company activities or within ESA projects. Many of these tools have been either developed for or used in EO and science mission analysis studies.

The following list gives a quick glimpse on the areas covered by the tools available in DEIMOS for EO and science studies, meant to give an idea of the broad spectrum of disciplines that are currently covered by our tools.

Orbit Design Sun-synchronous orbit design Frozen orbit design Orbit selection Spatial sampling Temporal sampling Orbit Analysis Detailed orbit propagation Atmospheric density Atomic oxygen Orbit evolution Eclipses Space Environment Radiation environment Absorbed dose Equivalent damage Micrometeoroids Space debris Coverage Analysis Swath visualisation and analysis Detailed Areas-of-Interest analysis Time to full coverage Revisit times Sun-glint Cloud cover Event Analysis GANTT visualisation Event handling Mission planning

DEIMOS Ground Segment Products
DEIMOS Ground Segments are based on the gs4EO suite of products. These state-of-the-art products are the result of more than a decade of work for the European Space Agency, specially evolved for supporting small Earth Observation missions.

The ground segment is built using a combination of 4EO products, working in a coherent and synchronized way, although all of them can also be used as independent applications. Each application communicates with the remaining Ground Segment using file-based interfaces, easing its integration with other external solutions.

Each of them is controlled by means of advanced user interfaces, in many cases web-based, and can be operated remotely. They are also highly configurable, using XML files.

Their main characteristics can be summarised as follows: State-of-the art. Proven operationally at ESA. Flexibility. Scalability. User Friendly. Designed for maximising S/C return. These products are already being used in different ESA and Spanish Governmental missions, like plan4EO or monitor4EO, used by Sentinel-2, or archive4EO, process4EO and calval4EO in Ingenio/SEOSAT, and all of them are the basis for the Ground Segment of DEIMOS missions (DEIMOS-1 & DEIMOS-2).
