Tenders are invited for: Compact high-performance pdhu for small satellites - expro plus
Tender issueThis activity aims to design and develop a Compact High-Performance PayloadData Handling Unit (PDHU) with very high functional integration for implementationon small satellites.The Payload Data Handing Unit (PDHU) manages in a single frameimplementation the complete chains of data acquisition and monitoring frompayloads and from On-Board Computer system (OBC) as well as integrated highendPDHU data processing functions such as data compression data encryption data storage channel formatting and data downlink.The PDHU itself is designed to be controlled by the OBC of a satellite.Telecommands are received from the OBC and telemetry data is transmitted to theOBC (protocol based on PUS is proposed).
Multi-payload scientific missions (with or without a dedicated PDHU
) are the target for this type of development.
