Data State Description
Dead Reckoned
A long period of time has passed since an actual
measurement of the data was received. Since that time,
the data has been adjusted to make it correct for the
current time. However, this adjustment (performed using
a dead reckoning or estimation algorithm) may not be
very accurate. When data is dead-reckoned, it is
considered usable, but degraded.
Implausible
The data is not within reasonable limits or it is changing
at an unreasonable rate. When this applies, the data is
considered unusable.
