Space telemetry protocols based upon recommendations by the Consultative Committee for Space Data Systems (CCSDS) are gaining wide acceptance within the international space telemetry community. These recommendations specify a very powerful interleaved Reed-Solomon code to protect its multi-layered, datadriven protocol format. As spacecraft telemetry data rates continue to increase, the computationally intensive nature of Reed-Solomon error correction requires a high-performance solution for space telemetry acquisition systems. This paper describes the development of a single-chip deinterleaving Reed-Solomon Error Correction decoder that demonstrates low-cost error correction for CCSDS-compatible data streams. This ReedSolomon Error Correction chip, designed to operate at rates up to 300 Megabits per second (Mbps), also incorporates additional onchip features such as cumulative quality accounting, real-time quality trailer generation, and fill frame removal.
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.
