چکیده
In this paper we propose an approach to improve the object location accuracy and enable better attitude estimation for wireless locating systems. This method combines the position data of multiple tags placed on an object. The algorithm is independent of the technology used to measure the tags position or the methods of pre-processing the data. The algorithm has been tested experimentally with an Ubisense system based on ultra wide band (UWB) communication. It has been demonstrated that the accuracy can be improved by a factor of three down to a couple of centimetres. This improved accuracy allows estimating not only the location but also the attitude of an object.

متن کاملOn Selecting Nodes to Improve Estimated Positions
We consider node localization problems in ad hoc wireless networks in which two types of nodes are considered: nodes with self-locating capability like GPS and nodes with no self-locating capability. Our simple algorithm for improving the position accuracy consists of selecting and processing only the nodes that are likely to enhance the position estimation. We focus our approach on defining a ...
