Poke CCSDS

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

Supported 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

Managed Parameters

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

TC

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

TM

tm_frame_length: TM transfer frame length.

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

AOS

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

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

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.
