A monotonically increasing positive integer.
Expected or predicted time at which state is
established.
If expressed in relative terms, then
stateStartTime is the time at which an
event is to occur expressed relative to the
scheduledCarrierStartTime of the
SpaceLinkSession data set referencing the
carrier profile associated with the space link
events profile.
An offset that is subtracted from the
stateStartTime providing the earliest time
that the carrier acquisition may occur.
An offset that is added to the
stateStartTime providing the latest time
that the carrier acquisition may occur.
Expected or predicted time at which the state is
terminated.
If expressed in relative terms, then
stateEndTime is the time at which an event
is to occur expressed relative to the
scheduledCarrierStartTime of the
SpaceLinkSession data set referencing the
carrier profile associated with the space link
events profile.
An offset that is subtracted from the
stateEndTime providing the earliest time
that the carrier lock may be lost.
An offset that is added to the stateEndTime
providing the latest time that the carrier lock
