When combining data from various sensors it is vital to acknowledge possible measurement delays. Furthermore, the sensor fusion algorithm, often a Kalman filter, should be modified in order to handle the delay. This paper examines different possibilities for handling delays and applies a new technique to a sensor fusion system for estamating the location of an Autonomous Guided Vehicle. The sys...

State estimation in the energy management center of active distribution networks has attracted many attentions. Considering an increase in complexity and real-time management of active distribution networks and knowing the network information at each time instant are necessary. This article presents a two-step multi-area state estimation method in balanced active distribution networks. The prop...

This document describes a protocol for a Device to provide locationrelated measurement data to a Location Information Server (LIS) within a request for location information. Location-related measurement information provides observations concerning properties related to the position of a Device; this information could be data about network attachment or about the physical environment. A LIS is a...
