*Page iv: "Observer agencies":

The National Space Organization (NSPO)/Chinese Taipei ceased in 2023, and has been replaced sinceby TASA: Taiwan Space Agency. The corresponding line could be updated

"Swedish Space Corporation (SSC)" changed its name. It is now SSC Space. It should be therefore written SSC Space/Sweden.

Note: these 2 generic comments concernall the books.

*Page 2-8: Paragraph 2.1.3 SUPERVISORY PROTOCOL DATA UNITS:

It is written "configuring the ranging channel and taking range measurements". Maybe "ranging" could be replaced by "PN ranging" ?

*Page 2-12: end of paragraph 2.3.1 "General":

It is written: "The applicability of the FOP-P and FARM-P for ersion-4 Transfer Frames is specified in reference [7].".  "ersion-4" shall be replaced by "Version-4".

*Page 2-12: paragraph 2.3.2.1 "General":

It is written "The COP-P procedure provides Sequence Controlled and Expedited service that determines how reliably SDUs are delivered from the sender to the receiver".

Maybe the following sentence could be better: The COP-P procedure provides Sequence Controlled and Expedited services that determine how reliably SDUs are delivered from the sender to the receiver"

*Page 3-7: table 3-2: Variable-Length Supervisory Protocol Data Unit

« Time Distribution PDU » looks to not have the same police or size of police than for the rest of the "Type" lines.

*Page 5-3: paragraph 5.1.2.2.1: Overview :

It is written:

  *   SPDU Type 4 (ANNEX D) includes the LEC directive, which is a 56-bit long.
  *   SPDU Type 5 (Annex E) includes a more advanced LEC directive, which is 96 bits long.

To be consistent with the rest of the document, "96 bits long" could be replaced by "96-bit long".

*Page 5-7: Paragraph 5.2.2.2:  Y (COMM-CHANGE):

It is written:

"(COMM_CHANGE) shall be used to track the sub-states during the commanding of a PL communications change". To be consistent with paragraph 5.2.2.2.1, "communications" should be replaced by "communication". Same remark for page 5-8, paragraph 5.2.2.3 : Z (SYMBOL_INLOCK_STATUS).

*Page 5-23 : Paragraph 5.4.3: Drawing untitled "HALF DUPLEX OPERA":

The title of the drawing should be replaced by HALF DUPLEX OPERATION"
