On-Board Wireless Communications for Spacecraft Test and Operations

摘要

This paper discusses recent activities at JPL that are focused on the development of wireless communications for data path connectivity between instruments and subsystems within the confines of a single spacecraft. Anticipated benefits of intra-spacecraft wireless links include reduction of cable mass, improved flexibility in spacecraft design or modifications and increased efficiencies during integration and test. This paper describes the framework for this effort, plans for retiring key risks and progress to date. Three of the primary risks addressed under this effort are communications link reliability, scalability and electromagnetic compatibility. In this paper, we will discuss analysis and test methods used to investigate each of these areas. In addition, we will describe a number of use cases for both operational and test applications that are under current investigation and development.
