DOG-M1 Multi-Mission Optical Modem

The DOG-M1 Multi-Mission Optical Modem is part of the A-Series, a family of next-generation satellite modem platforms built on versatile FPGA- and software-based architecture. It is specifically designed for optical communication up to multi-GHz bandwidths, supporting a full variety of space missions from LEO to Deep Space. The modem processes Optical On-Off-Keying (O3K) and High-Photon-Efficiency (HPE) transmissions via a common input, operating based on hard-decision decoding or the processing of logarithmic-likelihood-ratios (LLR). Through an all-IP structure, the platform supports both native network operation and data streaming over IP, with built-in protocol stacks for various space data formats and transparent baseband data streaming. The additional front-end digitizer unit DOG-F1 Optical Modem Front-End is available for signal processing from symbol synchronization to LLR computation in combination with the DOG-M1 for soft-decision input signals, allowing independent installation from the telescope location.
