The Abaco Systems/SBS 4427-V is a VMEbus-based CCSDS Encoder/Decoder Module providing independent encoding and decoding operations compliant with Consultative Committee for Space Data Systems standards. The module implements telemetry channel coding defined in CCSDS 101.0-B-3, delivering hardware-accelerated signal processing for space communications payloads.
Technical Specifications
The encoder implements convolutional encoding, Reed-Solomon encoding, symbol interleaving, Attached Sync Marker (ASM) insertion, and bit-stream randomization. Decoding functions include Viterbi decoding, Reed-Solomon decoding, symbol deinterleaving, frame synchronization, and bit-stream derandomization. All setup parameters and status readback interface through VMEbus connectivity.
