TELETEL was selected by Thales Alenia Space UK and OHB for the design, development and delivery of the PLATO CDMS SCOE (2 sets). The PLATO CDMS SCOE will be based on the iSAFT SpaceWire Simulator/Recorder and the iSAFT MIL-STD-1553 Simulator/Recorder products. The Power and I/O Front Ends will be realised by COTS HW components controlled by the iSAFT software. Platform and Payload Software Simulation Models will also be developed. The two CDMS SCOE sets will be delivered to the customers in Q1 and Q2 2021 respectively.
