A monotonically increasing positive integer.<br />

Expected or predicted time at which state is<br />

established.<br />

If expressed in relative terms, then<br />

stateStartTime is the time at which an<br />

event is to occur expressed relative to the<br />

scheduledCarrierStartTime of the<br />

<strong>Space</strong><strong>Link</strong>Session data set referencing the<br />

carrier profile associated with the space link<br />

events profile.<br />

An offset that is subtracted from the<br />

stateStartTime providing the earliest time<br />

that the carrier acquisition may occur.<br />

An offset that is added to the<br />

stateStartTime providing the latest time<br />

that the carrier acquisition may occur.<br />

Expected or predicted time at which the state is<br />

terminated.<br />

If expressed in relative terms, then<br />

stateEndTime is the time at which an event<br />

is to occur expressed relative to the<br />

scheduledCarrierStartTime of the<br />

<strong>Space</strong><strong>Link</strong>Session data set referencing the<br />

carrier profile associated with the space link<br />

events profile.<br />

An offset that is subtracted from the<br />

stateEndTime providing the earliest time<br />

that the carrier lock may be lost.<br />

An offset that is added to the stateEndTime<br />

providing the latest time that the carrier lock<br />

may be lost.<br />
