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.
OHB Hellas' new project that focuses on SENSORS
OHB Hellas proudly presents you a new project that focuses on sensors. More specifically, a cyber-physical system, based on a network of sensors will be established for collecting various data from the physical world and transfer them into a central cyber system. These sensors will monitor many variables of interest during the satellite manufacturing and assembly line, like the temperature/humidity and pressure inside various halls and on specific components and GSE, and many others. At the same time, specific thresholds will be defined by the user, for having full control of all processes. At this moment, OHB Hellas is working on the state-of-art phase and in the next months a more detailed technical research is going to be occurred. But what is the ultimate goal of this project? SENSE would potentially lead to lower manufacturing costs, higher performances, higher reliability, and shorter time to market, actions that enhance the efficiency that OHB Hellas indicates as a company.
OHB Hellas' participation in ODIN's EYE Project
The European Commission has selected OHB System AG, a subsidiary of space and technology group OHB SE, to lead a space surveillance and early warning project, named ODIN’S EYE (Multinational Development Initiative for a Space-based Missile Early-Warning Architecture). The project is funded by the European Defence Industrial Development Program (EDIDP). "The Project named ODIN'S EYE will set the basis for the development of an autonomous European early-warning capability against ballistic missiles and hypersonic threats", said Michele Bonerba, Project Manager and Head of Future Space Security Programmes at OHB. This important award confirms once again OHB’s leadership, know-how and strong commitment to serve the European strategic and security goals. ODIN’S EYE consists of a European consortium of 34 partners from 12 EU member states. Among them, there is an important Greek industrial participation with INTRACOM DEFENSE that will focus on state of the art technologies in Secure Communications and Cybersecurity frameworks and OHB Hellas, with its main expertise on the development of On-Board Sensor Data Processing technologies for satellite platforms. This marks also the first presence of Greek industries in a European Space Defence project under the EDIDP-EDF framework.
Athens Satellite & Space Summit Conference
OHB Hellas participated at the Athens Satellite & Space Summit Conference, with the thematic "Greece at the gates of the Space and Satellite Industry", on Wednesday 7th of July. Our Managing Director, Dr. Aikaterini Panopoulou, delivered a speech and presented the company’s actions, mission and next steps in depth, with the title being “Greece needs more space”. The Conference mainly focused on the Greek Space and Satellite Technology sector and its prospects in a market. Lastly, it was held under the auspices of the Ministry of Digital Government and the National Telecommunications and Post Commission (EETT) and is organized by Teamworks.
Space technology in the German-Hellenic Economic Forum
Space technology has been announced by the Greek Minister of Development and Investments, Mr. Adonis Georgiadis, as one of the areas of bilateral collaboration at the German-Hellenic Economic Forum in Berlin on 9th March 2020 under the patronage of the Chancellor and the Greek Prime Minister. The German Economic Affairs and Energy Minister Peter Altmaier said that the opportunity must be seized to make Greece the new “success story”, stressing that there was agreement in many areas with the new Greek government. OHB SE, represented by Marco Fuchs and OHB Hellas, represented by Katerina Panopoulou is proud for its contribution to this effort. The OHB representatives had B2B meetings with the Greek Minister and vice Ministers Development and Investments as well as with the vice Minister of the Ministry of Exterior. OHB Hellas participated in the panel about Growth and Innovation presenting scenarios of bilateral collaboration in space between Germany and Greece with Moderator Dr. Christian Geinitz from the Frankfurter Allgemeine Zeitung. Next target would be the preparation towards the signature of G2G agreement / Memorandum of Intent on bilateral cooperation in space technologies and applications at the 85th Thessaloniki International Fair (TIF) on 05. - 13. 09. 2020, where Germany is the country of honor.
