Projects

The objectives of @BUS High Performance Constant Conductance Heat Pipe project is to develop, design and test new high performance heat pipes (in the range 500 to 700 Wm) with a limited weight target and constant conductance performances.

The aim of this project is to design, develop, manufacture and test a High performance Loop Heat Pipe for a deployable radiator (in the frame of AlphaBus program) and large power range applications.

The interest in heat pipes as a capillary driven heat transfer device is based on its ability to transport thermal energy at high rates and with small temperature gradients. So the main objective of this project is to develop a European High Temperature Constant Conductance Heat Pipe (HTCCHP) for Alphabus, because the present trend is to increase the operational temperature of dissipating units and consequently, the working temperature range of heat pipe networks.

might be envisaged for satellite telecommunications payloads.

This project is aimed at the identification, analysis and optimisation of adaptive Fading Mitigation Techniques (FMT) together with the corresponding protocols, signalling information and formats in order to significantly increase the efficiency of future broadband DVB-RCS based satellite systems.

The objective of the Next Generation Antenna (NGA) programme is to generate a range of advanced antenna solutions which meet the evolving Ku and Ka Band market requirements for increased flexibility and performance whilst also increasing value for money.

The scope of this project was to perform a survey of the main companies in competing countries outside Europe carrying out Satellite Communications Systems (SATCOM) technological development.

The study aims at identifying opportunities for European Union satellite operators and service providers in all countries acceding to the European Union in 2004 (Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovak Republic and Slovenia). In addition, a Desk Research study of telecomms capabilities of neighbouring countries (Croatia, Bosnia-Herzegovina, Macedonia, FR of Yugoslavia, Romania, Albania, Bulgaria and Turkey) will be carried out.

This project is aimed at providing to ESA a comprehensive understanding and perspective on the developing market for multimedia satellite services, within the context of the broader multimedia industry.

The survey moves from the identification of the Companies that are active in the Telecommunication Market and, through the characterisation of each Company profile, aims at defining the major areas for a possible co-operation between the Industry of Greece and the Agency.

This study aims at gaining a good understanding of the likely evolution of satellite broadcasting during the period 2001-2007 in order to adequately plan the required developments for the future generation of broadcasting satellites.

The objective of this project is to conduct a study into the feasibility and viability of including a Short Messaging Service (SMS) within Galileo.

The ultimate technical goal is to qualify for 2006 / 2007 a life capable Hall effect thruster with specific impulse higher than 2500 s (50 % higher than the current state of the art) and a power as high as 5 kW (three times more than the current qualified European Hall effect thrusters).

The objective of this activity is to explore the future role of satellites in the context of personal communication beyond the timeframe for communications systems considered implemented in the short to medium term.

The project defined the major areas for a possible cooperation between the Portuguese telecommunications industry and the Agency and identified the most appropriate initiatives to be set up by ESA Telecom.

A new generation of PCU shall be developed in order to improve its competitiveness in terms of mass, efficiency, power modularity and above all cost.

The objective of this study is to improve the knowledge about propagation effects, climatological influence and propagation modelling for Satcom and Satnav systems providing services in tropical and sub-tropical regions.

The Mobile TV S-Band Repeater project aims to develop and qualify S-Band repeaters, ensuring Thales Alenia Space - España's leadership in future S-Band repeaters management opportunities.

The objective of this predevelopment activity for the new large European telecommunication platform is to develop, design, manufacture and test a new generation of deployable radiators with higher thermal performance and lower mass than existing aluminium/honeycomb panels.

SMM proposes the launch of one or more small-class geostationary satellites, featuring Ka-band spot beam payloads, in order to reduce satellite broadband service costs by an order of magnitude and bring them into line with terrestrial offerings.

The objective of this study is to assess the competitive situation between satellite and terrestrial communications networks in the Location Based Services market in the medium term (2005-2010).

The main objective of this study is to provide the European industry with pragmatic information and guidelines for the implementation of DVB-RCS services in two target regions, Latin America and Africa.

The objective of the activity is to develop an Active Pixel Sensor (APS) based star sensor compliant with the Alphabus/Large Platform Development. The pre-development activities are important to reduce the schedule and technical risk of the overall large platform development. The purpose of this activity is to analyse the economic interest, to develop and to test an elegant breadboard of an APS based star sensor.

The main objective of this study is to explore the grounds for the development and operation of a European stratospheric platform based on a sound analysis of possible service areas - mainly in the area of telecommunications, assessment of available and future technologies, to perform a conceptual design for the best suited platform concept answering the needs of future telecommunication markets.

The objective of this study is to assess the feasibility and commercial viability of a scalable approach using smaller satellites for providing satellite communication to new markets, services and applications.

The Project will demonstrate the concepts and schemes proposed for the end to end integrated communications scenarios, with focus on the provisioning of QoS aware communication services across heterogeneous domains.

The objective of this activity is to assess the feasibility of a high-resolution accelerometer in order to increase the station keeping autonomy in relation with the electric engine of the @BUS platform.

The Objective of the Project is the development of a Study on the current status and the expected evolution of High Definition Television deployments via Satellite in the world, with the aim of identifying which are going to be the potential business development of such new applications in Europe and Canada.

Satellite signal processing using an off-the-shelf AI chipset project is to develop and validate AI-based signal processing techniques for satellite telecommunications such as signal identification, spectrum monitoring, spectrum sharing, and signal demodulation using Off-theShelf AI accelerators.

The project studies the best approach for implementing feeder links in future Non-Geostationary communication constellations:

• RF feeder link using Super High Frequency bands (Ka or Ku)

• RF feeder link using Extremely High Frequency EHF (Q/V and/or W)

• Optical feeder links

Different Low Earth Orbit (LEO) scenarios are implemented to simulate the feeder link designs with a focus on topology, implementation, operations and service-level impacts.
