A reconfigurable computer optimized for spacecraft instrument use called the Adaptive Instrument Module (AIM) is under development and scheduled for launch in November 2000 on the Australian Fedsat spacecraft. The advent of RAM-based FPGAs whose configuration can be changed at any time has enabled the development of a low cost reconfigurable computer for space use. Reconfigurable computers provide solutions to problems that are uniquely found in spacecraft applications, but difficulties in using RAM-based FPGAs in the space environment must be overcome. The development of the AIM will allow future satellite programs to avoid the large costs associated with new builds by reconfiguring standardized processing hardware.
