“…The objective of information fusion is to obtain more information than is present in any individual information source by combining information from different sources [17]. In practice, this means that by utilizing the complementary properties of the different information sources, the information fusion algorithm in a navigation application aims to reduce ambiguities in the measured information and thereby expand the spatial and temporal coverage in which the navigation system works.…”

“…Here, data generally arrives at the fusion center at multiple rates asynchronously. Publications on asynchronous data fusion for discrete time systems include approaches based on multiscale system theory [7][8][9][10], batch process methods [11], algorithms based on multirate filter banks [12], etc. Although the Kalman filter (KF) output is in discrete time, the dynamics is often described in continuous time.…”

“…For sensors having different sampling rates at different scales, multiscale system theory is a useful tool. Our work stems from multiscale system theory but provides a new multiscale modeling architecture that is not limited to the wavelet [10,11,33]. In [11], the state at a coarser scale is modeled by the moving average of states at the finest scale; in [11] and [33], the backward model and the forward model were presented, respectively, through certain modifications of the moving average model.…”

“…Hong [11] proposed an algorithm for multi-resolutional distributed filtering with the wavelet transform as a linking mechanism between different resolution sensor domains. Yan et al [27] presented a novel fusion algorithm for multiple asynchronous multi-rate sensors by establishing state-space models for each scale and recursively fusing the data from many sensors, where the ratio between the sampling rates of different sensors is allowed to be any positive integer. Alouani et al [1] proposed a general sensor-to-sensor-track fusion algorithm for multiple sensors that are asynchronous and have arbitrary communication rates.…”
