WeLEA Core Team

The core team consists of four sites: HPS, LSS, FHP and RSG

High Performance Space Structure Systems GmbH (HPS) initiated the whole LEA-project, Frezite High Performance Lda. (FHP) has the role of the “administrative coordinator” of the consortium and will act with its huge experience in EU-projects as direct interface to the European Commission. HPS GmbH, specialized in high performance antennas, deployable structures and thermal hardware, takes the role of the “technical & implementation management”. Furthermore, it is responsible for the investigation of potential reference missions, the design and analysis (RF, mechanical, thermal, kinematic) of the LEA-subsystem, the development of the deployable arm assembly, the RF-reflecting metal mesh and for the management of the final test campaign of the PFM.

THE TEAM TO TRUST.

HPS Germany is responsible for the technical coordination of the whole Large Deployable Reflector Subsystem.

Our long experience in developing and building of advanced technologies and products for space applications expands from Reflector antennas, Large Deployable Reflector Subsystems and Deployable Sail Subsystems to Thermal Hardware, Nanosatellite Equipment, Lightweight Structures, Radiation Protection Components and Ground Support Equipment.

About

Large Space Structures GmbH, Germany, takes over the role of the deployable reflector assembly technical manager and is responsible for associated design, analysis, manufacturing and testing.
The company’s key person holds the most profound heritage in the field of large deployable reflectors in Europe, has developed so far more than 15 different kinds of deployable reflectors and had acted as a main manager from Georgian side on a 6m reflector technology development for the MIR space station with successful flight test as early as 1999.

About

RUAG Space Germany, Germany, a member of the Swiss RUAG AG, is developing, building and testing the deployable hinges of the LEA deployable arm assembly and is responsible for all hold-down and release mechanisms of the LEA-subsystem.  Since more than 20 years RSG (former HTS GmbH) specializes in mechanisms and mechanical components for space applications. In close cooperation with companies, universities and research institutes RSG develops innovative ideas, components and products for national and European space programs and industrial applications.

WeLEA Core Team Support

In regard to legal and patent aspects the whole LEA-Team is supported by Weber Steinhaus & Smith (Germany). Its key person has an extensive command in the field of national and international space law, particularly from a commercial point of view.

About

Weber-Steinhaus & Smith focuses on commercial advisory work and litigation at national and international level. Located in the Bremen Cotton Exchange, this select practice continues to provide advice in trade and commodity matters and is actively involved in arbitration.

Its fields of expertise range from contractual disputes, competition law and space law to insolvency law and company law. Notarial services of private and commercial nature are offered by Dr. Weber-Steinhaus.

About

OHB and Thales Alenia Space (Joint Venture between Thales, 66%, and Leonardo, 33%, France) are contributing to the review of potential reference missions and take care of accommodation aspects and system-level requirements. Both Large System Integrators (LSI) have a big overview on current mission demands and the needs from satellite point of view.

WeLEA Hardware Team

The Hardware Team consists of von Hoerner & Sulger (VHS), Luma Metall (Sweden), Invent (Germany) and HPS Lda. (Portugal)

About

Specialist for electronics for scientific and commercial space missions is taking responsibility for the design and development of all on-board electrical equipment such as power, control, monitoring of all LEA mechanisms and the harness from LEA electronics to arm and antenna motor units. In addition, the SME delivers the Electrical Ground Support Equipment (EGSE) hardware that functions as interface to LEA electronics.

About

Luma Metall is providing kilometers of very thin gold-plated metal wire for the mesh development samples and the PFM mesh. Investigations on optimizing the wire specifically for reflector mesh applications will be performed.

About

As a specialist for manufacturing of composite structures for aerospace applications, INVENT is going to manufacture the several meters long carbon composite booms for the deployable arm. The long years’ experience of this SME will lead to a very lightweight and highly accurate product, important for the whole antenna performance in space.

About

Besides its role as general project coordinator, FHP Lda will contribute on element-level with its extensive experience in deployable structures, composite materials and processes as well as thermal hardware: the company will provide highly accurate CFRP-struts with metallic end-fittings for the reflector assembly.

WeLEA Service Team

Indispensable services in the framework of this project are coming from Spain (INTA), Denmark (TICRA), Portugal (INEGI), and Germany (Etamax and Airbus Defence & Space)

About

As the world’s leading supplier of accurate reflector antenna modelling software, TICRA (Denmark) will provide radio frequency (RF) simulations of the large reflector antenna performance throughout the LEA-project. The simulations will be based on a detailed RF-model of the LEA reflector and feed geometry of the PFM in the GRASP software. Simulated results will finally be correlated with measured RF-data.

About

ETAMAX Space will bring in its software engineering capacities for the development of the EGSE software for testing the deployment of the LEA controlling motors and sensors with different profiles Furthermore, ETAMAX will perform a meteoroid and space debris risk analysis ensuring a higher reliability and survivability of the antenna as support to the design team.

About

INEGI, the Portuguese Institute of Science and Innovation in Mechanical and Industrial Engineering from the University of Porto, will focus on development, design, manufacturing and integration of several ground support equipment (GSE) required for the LEA subsystem evaluation. This includes a zero-g device for reflector and arm deployment, the adaptors for vibration and TVAC testing as well as thermo-elastic distortion (TED) testing GSE.

About

INTA, the National Institute for Aerospace Technology in Spain, is going to provide thermal, vibration, and shock tests for both arm and the reflector on stowed configuration as well as associated tests on component level including PIM and RF reflection losses on sample level. INTA contributes well to the project with its large facilities and related test experience and wants to develop its service area to meeting the requirements for testing large deployable structures.

About

Airbus Defence & Space runs the Antenna Test Center in Ottobrunn and will conduct the final RF-performance testing of the LEA PFM. This project will be another application for the newly developed measurement tool for large antennas, moving above a static item under test. Standard RF test equipment collides with boundary conditions of necessary test setups in order to successfully simulate space environment for such large antennas.
