poke-ccsds is a GNU poke pickle for analyzing CCSDS protocols.

• Space Packet Protocol
• Encapsulation Packet Protocol
• TM Space Data Link Protocol
• TC Space Data Link Protocol
• AOS Space Data Link Protocol
• Unified Space Data Link Protocol
• Space Data Link Security Protocol

Many CCSDS protocols include "managed parameters" which affect the structure of the frames. These parameters must be configured after loading the pickle.

tc_fecf_present: Bit indicating the presence of the frame error control field.

tm_frame_length: TM transfer frame length.

tm_fecf_present: Bit indicating the presence of the frame error control field.

aos_fhec_present: Bit indicating the presence of the frame header error control field.

aos_insert_zone_length: AOS insert zone length, 0 for not present.

aos_frame_length: AOS transfer frame length.

aos_fecf_present: Bit indicating the presence of the frame error control field.

aos_ocf_present: Array of bits indicating the presence of the operational control field for each virtual channel.

uslp_insert_zone_length: USLP insert zone length, 0 for not present.

uslp_frame_length:AOS transfer frame length.

uslp_ocf_present: Bit indicating the presence of the operational control field.

uslp_fecf_present: Bit indicating the presence of the frame error control field.

sdls_iv_length: IV field length.

sdls_seq_length: Sequence number field length.

sdls_pad_len_length: Pad length field length.

sdls_mac_length: Message authentication code length.
