((hat {x}(t),hat {y}(t))) is the position estimated by the trilateration method.
Whenever an object goes across the gates, the registered ID by an identification sensor is associated with the position estimated by a visual sensor.
where σ m,n2 corresponds to the intrinsic range measurement variance between node m and n and (text {tr}({sigma ^{2}_{n}})) is the trace of the position estimated covariance matrix.
Typically, when a user rejects the position estimated by the system, the reason could be that the user is nowhere near any of the anchors known by the system.
The position estimated by the Kalman filter has an increased accuracy because the filter combines two types of information with complementary properties: reading from INS is short term accurate with an unbounded increasing error, and location estimation based RSSI is characterized by a bounded positioning error.
Société Générale, already on the ropes for its exposure to U.S. subprime mortgage securities, had to quickly unwind the position, estimated in the tens of billions of euros, and selling had to be done amid a global market free-fall on Monday.

After obtaining the uncertainty for the position estimates, emitters with estimated positions near (within σPSF/2) or outside of the sub-region boundary are discarded.
Furthermore, when we recompute pairwise distance estimates from the position estimates, we see that joint estimation using MDS improves the results.
Looking at the position estimates when using only the long-time average peak in Figure 8, the results seem questionable.
The positions estimated via simple integration are typically far from the optimum value.
The main question would then be how much the Kalman filter and the combination of heterogeneous networks would improve the positioning estimates in critical scenarios.
