The components that comprise the Advanced Responsive Tactically Effective Military Imaging Spectrometer (ARTEMIS) payload processor, to be deployed on the AFRL TacSat-3 satellite, provide a flexible and high-performance platform upon which space imaging applications can be deployed. The payload system consists of an FPGA camera interface and processing board as well as a G4-based single board computer among other components. The combination of FPGA and generalpurpose processor provides resources attuned to strike a balance between compute-intensive sensor data extraction processing and administrative tasks such as health monitoring and information downlink. This paper provides a description of the system design and highlights the system's performance and flexibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
