The activities concern the design, development and qualification of a PCDU (Power Conditioning and Distribution Unit), using an EQM Model, that is optimized for satellites dedicated to the SATCOM constellation market for which an unregulated 22V/38V bus has been selected (best compromise between needed power and cost).
The main issue addressed is to perform technical and economic trade-off, focusing on the low cost target.
The qualification of the PCDU for Satcom Constellation will allow TAS-ETCA to bring the electrical developments to a level where the design can be confidently validated at IRIDIUM Next system level.
The PCDU architecture is based on the following guidelines:
Project plan consists in the following main activities:
