Systemobservability is examined and two necessary conditions for the system to be observable are obtained.
首先分析了系统的观测性,得出了系统可观测的两个必要条件。

From the systemobservability analysis, adding more kinds of external measurements into the inertial navigation system can enhance estimation accuracy of INS error.
The minimum number of sensors for observing a normal structure and a structure with repeated frequencies is studied respectively based on dynamic systemobservability.
