measurement noise associated with fiber optic gyroscopes continue to remain a key confinement to their efficiency in high-end applications.
W(k) is M-dimension process noise vector, V(k) is N-dimension
measurement noise vector, W(k) as well as V(k) can be modeled as Gaussian white noise and satisfy the following normal distribution:
Equivalent
measurement noise [[bar.[eta]].sub.k] is a Gaussian white noise with zero mean and covariance matrix [[bar.R].sub.k] = E{[[bar.[eta]].sub.k] [[bar.[eta]].sup.T.sub.k] = ([[bar.[R]].sup.i,j,sub.k]), and we further have
In this paper, the process noise [w.sub.n] [member of] [R.sup.q] and
measurement noise [mathematical expression not reproducible] are assumed to be correlated white noises with zero mean and
where d(p) = [([d.sub.1](p), [d.sub.2](p), ..., [d.sub.i](p), ..., [d.sub.N](p)).sup.T] is the vector of real distances between the vehicle and transponders [mathematical expression not reproducible] is the measurement of d(p); w represents the
measurement noise vector which cause ranging errors; COV = diag([[sigma].sup.2.sub.1], [[sigma].sup.2.sub.2],..., [[sigma].sup.2.sub.i], ...
A suitable selection of process noise and
measurement noise covariance matrices is important in EKF estimation.

where W is the system noise, v is the
measurement noise, G is the system noise driving matrix, and y is the vector of the measurement value.
Figure 1 shows the cumulative distribution function (CDF) of
measurement noise and NLOS error.

measurement noise," IET Control Theory & Applications, vol.
The approach in that paper is rather weak in the presence of unknown
measurement noise. Therefore, the state estimation problem of JMS for target tracking systems in the presence of unknown noise and steering command is an interesting topic to pursue.
