However, the exact definition of the structure of the Service 6 packets as well as the generation of the required patch
and dump commands is the responsibility of mission specific implementations and/or extensions. Thus, no specific
constraint applies in the definition of the relevant structures. In order to re-use existing implementations of the
OBSM TM/TC functions, it is however recommended to adopt a structure which has already been used by a previous
SCOS-2000 based mission.

SERVICE 8: FUNCTION MANAGEMENT SERVICE
(see Section 12 of [AD-5])
There is no specific processing of Service 8 TM/TC packets in SCOS-2000.
Features/Limitations/Constraints:
There is no specific limitation in the processing of Service 8 packets.
3.8
SERVICE 9: TIME MANAGEMENT SERVICE
(see Section 13 of [AD-5])
The Time Report Packets are used by the SCOS-2000 Time Correlation in order to generate the so called Time
Couples (i.e. a given time expressed in On-Board Time and the corresponding UTC). The actual implementation of
this function, supporting both free-running and synchronized on-board clocks, will only be available as from SCOS2000-R5.2 (in previous versions the Time Correlation is considered as a mission specific function).
Features/Limitations/Constraints:
Service 9 permits the dynamic modification of the frequency of generation of Time Packets (see Section 13.3.1 of
[AD-5]). SCOS-2000 will not support any automatic update of the relevant parameters in the ground function on the
basis of the successful execution of Service (9,1) commands.
3.9
SERVICE 11: ON-BOARD OPERATIONS SCHEDULING SERVICE
(see Section 14 of [AD-5])
SCOS-2000 supports specific features related to the on-board operations scheduling service. In particular:
•
Commands associated to an execution time-tag are automatically ‘encapsulated’ in Service (11,4)
