德国 WORK  DOG-1 Multi-Mission Optical Modem 多任务光调制解调器

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-1 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).

An additional front-end device (DOG-FE Optical Modem Front-End) is available for signal processing from symbol  synchronization to LLR computation in combination with the DOG-1 for soft-decision input signals. That will also allow installations of the DOG-1 independently from the telescope location.


Key Features

  • Multi-Mission support

  • Hard-decision and soft-decision decoding

  • Optical On-Off Keying (O3K)

  • High-Photon-Efficiency (HPE) future upgradable extension

  • CCSDS 141.0-B-x support

  • CCSDS 142.0-B-x support

  • O3K symbol rate up to 10 Gsps

  • Internal storage for at least 2 LEO passes at maximum bandwidth

  • Customizable processing infrastructure for easy integration into large communication systems

  • Flexible software architecture for easy extension and future virtualization of functionality

  • Teleport-grade M&C capabilities for seamless integration into professional ground station systems
