Abstract
A data fusion architecture with a plurality of sensors, optionally position measuring equipment (PMEs), is described. Each sensor supplies measurement data x, x. . . xand is associated with accuracy data H, H. . . Hindicative of the accuracy of the supplied measurement data. Sub-processing units derives first estimates sf, sf. . . sfand second estimates Hn, Hn. . . Hnof the variability of the measurement data supplied by the respective sensor. The first estimates are derived by processing the measurement data x, x. . . xand the second estimates are derived by processing the accuracy data H, H. . . H. The first and second estimates are combined in a multiplier to derive overall estimates σ, σ. . . σof the variability of the measurement data supplied by the respective sensor. Data fusion means such as a Kalman filter combines the measurement data supplied by each sensor and the overall estimates σ, σ. . . σfor each sensor.
