• Resumen

  • On-board data handling system (OBDH) architectures form the foundation for managing data on a spacecraft. Data are typically the primary driver and motivation for space missions. Due to constraints such as available power and communication bandwidth, design of OBDH systems requires detailed analysis of requirements for the four primary data elements: sources, sinks, transfers, and processing. This chapter explores how to create a spacecraft data bus architecture and the considerations and best practices that go along with it. Discussions included the following: where data are generated, where the data go, methods for transferring data, how to process it, and how to keep time. Real mission examples from the radio explorer (RAX) mission are provided along with emerging trends in OBDH.
