The European Space Agency Tender

Objective:the Objective Of The Activity Is To Prepare The Development Of An Optimised 100gbps Coherent Transceiver For Satellite Free-space Optical Communications Through The Atmosphere. This Activity Shall Address The Optimisation Of The Digital Signal Processing, Including The Time-diversity Algorithms Based On The Current State-of-art Coherent Transceiver Solutions. It Shall Also Attempt To Implement A Time And Frequency Transfer Function.targeted Improvements:to Achieve Reliable Satellite-ground Bi-directional Communications Through The Use Of Space-optimised Coherent Transceivers. This Shall Improve One Order Of Magnitude The Current Optical Channel Capacity (current Missions With Dedicated Transceivers Are Targeting 10gbps).description:the Activity Will Build On Existing Cots Transceivers Design But Will Propose And Demonstrate The Required Optimisation For Cross-atmospheric Links. Transceiver Functionalities Related To The Optical Fibre Medium Shall Not Be Included, While Functionalities Required By The Free-space Links Will Be Introduced And Tested (e.g. Interleaving, Fec, Time Recovery, Carrier Frequency Recovery). The Main Tasks Are -state-of-art Analysis Of The Current Coherent Transceivers Implementation-design Of The Transceiver For Satellite Cross-atmospheric Links-scaled Breadboard Development And Testing Of The Selected Configuration In Laboratory Environment.
