Today’s satellites are inherently inflexible and purpose-built for a single mission, relying heavily on the ground segment to analyze data. The space market is looking for on-board flexibility / on-board reconfiguration targeting the digitalization of payload for earth observation and space exploration missions. Furthermore, there is an increasing interest for the availability of AI-oriented hardware devices allowing tasks such as deep learning inference and pre-processing of sensor data in-orbit.
OHB is constantly exploring disruptive approaches to propose its customer always better space-based solution. From its existing heritage in the domain, the company is exploring the possibility to transfer part of the processing of satellite data from the earth (ground segment) to space (space segment), through the development of so-called On-board Payload Data Processing (OPDP).
Some example of application:
- Data fusion on board
- Automatic optical sensor calibration
- End-to-End secured data transfer
- Filtering onboard the data of interest increasing the flexibility in usage of bandwidth, data storage and coverage.
The technology can be an enabler for new applications, for example:
- In-orbit distributed calculation
- fleet cooperation
- automation of mission control and operation
We are currently examining the possible combination of software framework and hardware from the use of AI accelerator to high-performance mixed-criticality avionics electronics. Our work includes design mitigation techniques to include this development in existing OHB satellite platform.
Based on the existing group heritage and competences concerning onboard data processing, OHB Hellas is strongly committed to providing a turn-key system with a combination of AI-oriented hardware and open software to bring intelligence on board while providing a high level of flexibility. This solution would enhance the group portfolio and further improve its competitiveness for future earth observation and space exploration missions.
