Annex a Glossary

From: TM Synchronization and Channel Coding is used to protect the transfer frames against telemetry channel noise‐induced errors. Reference [3] describes the CCSDS Recommended Standard for TM Synchronization and Channel Coding, including specification of a convolutional code, a Reed‐ Solomon block‐oriented code, a concatenated coding system consisting of a convolutional inner code and a Reed‐Solomon outer code, and of turbo codes. To: TM Synchronization and Channel Coding is used to protect the transfer frames against telemetry channel noise‐induced errors. Reference [3] describes the CCSDS Recommended Standard for TM Synchronization and Channel Coding, including specification of a convolutional code, a Reed‐ Solomon block‐oriented code, a concatenated coding system consisting of a convolutional inner code and a Reed‐Solomon outer code, turbo codes, and LDPC codes. Figure 2‐2 on page 2‐6 needs to have LDPC added. If interagency cross support requires one agency to decode the telemetry of another, then the codes recommended in reference [3] should be used. The recommended codes consist of: a constraint length 7, rate 1/2 convolutional code, and various punctured versions of it; (255,223) and
