Space Link Extension - Service Management - CCSDS

DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT
Parameter Name Parameter Definition/Description Data Type
minimumSessionDuration The minimum duration of space link session Positive
required. If multiple carriers are being requested Integer
via the referenced Space Link Session Profile, the
value of minimumSessionDuration
corresponds to the shortest duration that is viable
for the carrier that requires the longest duration in
the session.
NOTES:
1 If multiple carriers are being requested via the
referenced Space Link Session Profile, a
carrier may have duration shorter than
minimumSessionDuration if its
carrierStartTimeOffset and/or
carrierStopTimeOffset are non-zero
in the Space Link Session Profile.
2 If there are to be multiple acquisitions and loss
of signal (e.g., because of occulting planetary
body) for a given carrier, this parameter
indicates the minimum duration for the entire
contact, including the intervening loss(es) of
signal.
preferredSessionDuration The preferred duration of the space link session.
If multiple carriers are being requested via the
referenced Space Link Session Profile, the value
of preferredSessionDuration
corresponds to the desired duration of the carrier
that requires the longest duration in the session.
NOTES:
1 This can also be thought of as a maximum
acquisition contact duration desired by UM.
2 If there are multiple acquisitions and loss of
signal (e.g., because of occulting planetary
body) for a given carrier, this parameter
indicates the preferred duration for the entire
contact, including the intervening loss(es) of
signal.
sequenceOfEventsDeferred Indicates if the sequences of events are deferred
from the initial version of the Service Package
and are to be supplied at a later time”
– ‘true’—the sequences of events are
deferred (i.e., not included);
– ‘false’—the sequence of events are not
deferred (i.e., they are included).
transferServicesDeferred Indicates if the transfer services are deferred
from the initial version of the Service Package
and are to be supplied at a later time:
– ‘true’—the transfer services are deferred
(i.e., not included);
– ‘false’—the transfer services are not
deferred (i.e., they are included).
