Detection Chain Electronics
Detection Chain Electronics from Jena-Optronik include the electro-optical conversion from the image sensor itself up to the pre-processed image data ready for storage
The electronic components of the Detection Chain by Jena-Optronik GmbH include the development of state-of-the-art image sensors for the image data acquisition itself and their pre-processing and preparation via the front-end electronics and data processing electronics.
The individual components provide the following functionality:
- Provide telemetry data as discrete signals to monitor the sensor and sensor-related electronics
- Support of the in satellite commonly used used data bus Systems
- The commanding of the electronic components by discrete Signals
- Clock and synchronization signals for image acquisition and Transmission
- Signal adaptation and low-noise digital conversion of analogue video inputs with high-Resolution
- Real-time image pre-processing and data compression with configurable Parameters
- Data formatting and transfer to satellite storage including additional telemetry data
- Control and power supply of all components including the detectors
- Temperature Control
- TM/TC handling for control and commanding
- Compact design and thus weight-optimized design using sequencer FPGA with a high pin count based on CCGA package
