With the number of satellites in orbit greatly increasing each year, it is critical to thoroughly understand the space environment and define the dangers that it can present to spacecraft. OHB Hellas is glad to be part of ReTiMo, a small satellite mission led by Democritus University of Thrace and proposed to ESA, with its main goal being the monitoring of space weather.
Satellites in Low Earth Orbit (LEO) are exposed to energetic particles that impact their normal operation, creating upsets such as Single Event Effects (SEEs) that disrupt the nominal function of on-board electronics. Moreover, said particles induce surface charging that can affect hardware and also cause degradation of solar cells. ReTiMo aims to provide valuable data regarding spacecraft anomalies, advancing space weather monitoring and operational awareness in the LEO radiation environment.
The mission has been selected by ESA to be funded for a phase 0 feasibility study. Greek space systems engineers in OHB Hellas are responsible for delivering the mission concept definition, analysis, cost and schedule. The whole team is looking forward to the successful completion of the project.
We are very proud of our participation and contribution to the RAMFASAT experiment, a collaboration between FEAC Engineering, 3DHUB Greece and OHB Hellas that took place under the framework of AMable initiative, between July 2021 and May 2022.
RAMFASAT is an experiment that utilizes topology optimization and additive manufacturing techniques early in the design phase and manufacturing process, to redesign a critical component of the ADC (Attitude Determination and Control) System for Micro-Satellites.
The aim of this experiment was to:
- Achieve significant mass reduction and thus launch cost reduction
- Eliminate the limitations and restrictions from well-established manufacturing methods
- Simplify construction and assembly of the product
The final printed component, made of PEEK and NYLON in two different configurations, fulfilled all established requirements, paving the way for more widespread use of AM polymer applications in space.
Hellenic Center for Additive Manufacturing
OHB Hellas is proud to be one of the shareholders of the first Hellenic Center for Additive Manufacturing (HCAM), which will focus on producing end-to-end solutions in various sectors including space and aeronautics, with AM at its core.
The «Hellenic Center for Additive Manufacturing S.A. - HCAM» announced on 24 February, 2022 its establishment and start of operation in Patras, Greece.
HCAM S.A. will fill an existing gap with the creation of a Competence Center in 3D Printing technologies, in Greece and South-Eastern Europe. The recent example of the Covid-19 pandemic showed that immediate solutions can be found using 3D printing for medical support. In Greece, until now there was no dedicated Center to collect and respond to such requests at the scale needed. HCAM S.A. aspires to be a unique one-stop-shop providing end-to-end technological solutions and integrated services to companies, as well as research, training, development and education activities in the field of Additive Manufacturing for various sectors, such as energy, maritime, aerospace, medical, etc.
Nine (8) stakeholders of the Greek R&I ecosystem with a strong presence in Greece and internationally, participate in the shareholder structure of HCAM S.A., namely:
· CBL Patras S.A.
· Foundation for Research and Technology–Hellas (Foundation for Research and Technology - Hellas (FORTH))
· MIRTEC S.A. (EBETAM A.E.)
· MONOLITHOS Catalysts Ltd
· Neweleven Capital Ltd
· OHB HELLAS mon.E.P.E.
· Raymetrics Advanced Lidar Systems
· UBITECH Ltd
In its effort to become a center of excellence in Additive Manufacturing, to place Greece in a leading position in the field, and attract clients at a global scale, HCAM S.A. is seeking to recruit highly motivated professionals offering a competitive salary, an attractive benefits package, great opportunities for professional development, as well as an exciting, fresh and collaborative work environment. More information on new job postings will be available soon.
We want to acknowledge the General Secretariat for Research and Innovation (GSRI) for its support and funding through the Action ‘Competence Centers’, making a strong contribution to the enhancement of competitiveness in the region of Western Greece and in the whole Country.
