DOG-M1 Multi-Mission Optical Modem

The A-Series is a family of next generation satellite modem platforms built on versatile FPGA- and software-based architecture. The Digital Optical Groundstation (DOG) suite of products is designed for optical communication up to multi-GHz bandwidths, supporting the full variety of space missions from LEO to Deep Space. Exceptional analog and digital engineering provides teleport-grade devices with future-proof expandability.

Through an all-IP structure, the platform supports both native network operation as well as data streaming over IP. Built-in protocol stacks support an increasing number of space data formats as well as streaming of transparent baseband data and synchronized symbols for user-defined processing and integration into virtualized infrastructures.

The DOG-M1 Multi-Mission Optical Modem is a modem dedicated to support the processing of optical links between space and Earth. It is designed for multi-mission support to enable effective ground station design. Optical On-Off-Keying (O3K) and High-Photon-Efficiency (HPE) transmissions can be processed via a common input that operates either based on hard-decision decoding or the processing of logarithmic-likelihood-ratios (LLR).

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. That will also allow installations of the DOG-M1 independently from the telescope location.
