ccsds_aos_frames(FrameLength,InsertZoneLength,HasOCF,HasFECF)

  • FrameLength - Fixed AOS transfer frame length in octets.

  • InsertZoneLength - Length in octets of the optional insert zone when present.

  • HasOCF - Boolean indicating if frames include the operational control field.

  • HasFECF - Boolean indicating if frames include the frame error control field.

CCSDS advanced orbiting systems transfer frame parser and generator.

Public predicates

virtual_channel_frame_count/2

Extracts the virtual channel frame count.

Compilation flags:
static
Template:
virtual_channel_frame_count(Frame,Count)
Mode and number of proofs:
virtual_channel_frame_count(+compound,-integer) - one

signaling_field/2

Extracts the signaling field term.

Compilation flags:
static
Template:
signaling_field(Frame,SignalingField)
Mode and number of proofs:
signaling_field(+compound,-compound) - one

insert_zone/2

Extracts the optional insert zone. Returns none when absent.

Compilation flags:
static
Template:
insert_zone(Frame,InsertZone)
Mode and number of proofs:
insert_zone(+compound,-compound) - one

update_fecf/2

Computes the correct AOS transfer frame FECF for the selected object configuration and returns the corresponding updated frame term.

Compilation flags:
static
Template:
update_fecf(Frame,UpdatedFrame)
Mode and number of proofs:
update_fecf(+compound,-compound) - one_or_error
Exceptions:
Frame is a variable:
instantiation_error
Frame is neither a variable nor a valid AOS transfer frame term:
domain_error(ccsds_frame_term,Frame)

verify_fecf/1

True if the AOS transfer frame term contains the correct FECF for the selected object configuration.

Compilation flags:
static
Template:
verify_fecf(Frame)
Mode and number of proofs:
verify_fecf(@compound) - zero_or_one
