OHB System AG

Who we are...

OHB System AG is the largest member of the OHB SE group with more than 1700 employees in two main facilities in Germany: the headquarters in Bremen, located at the Technology Park, and the Space Centre Optics & Science in Oberpfaffenhofen (Munich area).OHB System is the leading German satellite manufacturer for compact up to high-end turnkey satellite solutions in Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) and for a launch mass of up to 4.000kg for geostationary satellites. The European Space Agency (ESA) has included OHB System into the definition as Large Systems Integrator, and today it is the third satellite prime in the European framework for telecommunications, navigation, space exploration, Earth observation & science.

HB also plays a key role in the development of the Galileo Full Operational Capability (FOC), where it is responsible to design and manufacture 34 FOC satellites, 22 of which are already in orbit. OHB is also

prominently involved in the development of Meteosat Third Generation (MTG), by being responsible fordevelopment of all six satellite platforms and in the lead of the overall development of the two Soundermission satellites (MTG-S), under Thales Alenia Space primeship.

OHB System AG is developing and building the hyperspectral satellite for the next German satellite missionEnMAP (Environmental Mapping and Analysis Program). OHB System AG signed on 31. July 2020 a contract with the ESA for the realisation of the CO2M Earth observation mission. The mission is part of the European Copernicus program and in its first stage of completion will consist of two satellites equipped with payloads specifically designed to measure carbon dioxide emissions caused by human activities. Planned launch is 2025. OHB System AG will also develop the payload for the two satellites of the Earth observation mission CHIME under a subcontract from Thales Alenia Space. The corresponding contract was signed on 19. Nov. 2020. CHIME (Copernicus Hyperspectral Imaging Mission) is part of the European Earth observation program Copernicus and is intended to contribute to the responsible and sustainable use of natural resources by means of hyperspectral analyses of the Earth's surface. Planned launch is 2028.

What are our tasks in CityCLIM?

Several European companies are involved in implementing the project, including four from the OHB Group: OHB System is acting as the project coordinator and is responsible for processing and providing the space-based Earth observation data. OHB Digital Connect will use an airborne system to validate the calculated model predictions with thermal infrared measurement data. OHB Digital Services is responsible for the development of the cloud-based data platform in which all input data will be consolidated and subsequently made available as City Climate Services. The implementation of service demonstrations in the four selected pilot cities is being organised by OHB Digital Solutions from Austria.

  • Project Coordination​
  • Providing and data processing of airborne data

Related skills and experience of the organisation

OHB System, as a large satellite integrator, has profound in-depth experience in leading space missions. OHB also has extensive heritage in mission analysis and system definition for customers like ESA, DLR (German Aerospace Center) and European Union (EU) and also from in-house activities or in direct cooperation with the mission Principal Investigators. Besides this mission analysis and definition experience, OHB has also extensive experience in instrument definition and design for various European scientific institutes including payloads and equipment.
