Ronald Mahler’s Probability Hypothesis Density (PHD) provides a promising framework for the passive coherent location of targets observed via multiple bistatic radar measurements. We apply a particle filter implementation of the Bayesian PHD filter to target tracking using both range and Doppler measurements from a simple non-directional receiver that exploits non-coöperative FM radio transmitt...

Abstract. The ESA mission BepiColombo, nowadays, represents a milestone for the precision levels that can be obtained in determination of orbit spacecraft. high accuracy provided by embedded radio system, together with modern techniques used calibration tropospheric noise, such as usage microwave radiometer, allows to estimate state spacecraft very small uncertainty. Doppler measurements collec...

The Namib Desert golden mole (Eremitalpa granti namibensis) is morphologically, physiologically and behaviourally specialized for living in the harsh loose-sand desert. Ecological studies have relied on visually tracking animals on the surface of sand dunes. A radio tag would allow individuals to be more reliably located, even while under the sand. We developed a radio attachment and gathered p...

I briefly outline our current observational understanding of the relativistic jets observed from X-ray binary systems, and how their study may shed light on analogous phenomena in Active Galactic Nuclei and Gamma Ray Bursts. How SKA may impact on this field is sketched, including the routine tracking of relativistic ejections to large distances from the binaries, detecting and monitoring the ra...

Location tracking systems are increasingly becoming the focus of research in the field of Wireless Sensor Network (WSN). Received Signal Strength (RSS)-based localization systems are at the forefront of tracking research applications. Radio location fingerprinting is one of the most promising indoor positioning approaches due to its powerful in terms of accuracy and cost. However, fingerprintin...

Information integration and total supply chain visibility are viewed as integral parts for supply chain excellence. Real time and accurate information on the status of goods in a supply chain requires the integration of several evolving technologies that enable tracking of items, cartons, totes, containers, trucks, ships, rails, and other conveyances continuously. In this article, we examine tr...

We describe a topic tracking system developed at GE R&D Center in connection with our participation in DARPA TDT evaluations. The TDT tracking task is specified as follows: given Nt training news stories on a topic, the system must find all subsequent stories on the same topic in all tracked news sources. These sources include radio and television news broadcasts, as well as newswire feeds. The...

Pedestrian dead reckoning is a common technique applied in indoor inertial navigation systems that is able to provide accurate tracking performance within short distances. Sensor drift is the main bottleneck in extending the system to long-distance and long-term tracking. In this paper, a hybrid system integrating traditional pedestrian dead reckoning based on the use of inertial measurement un...

Technical Data Analysis (TDA) presents the architecture development of its rotary wing dynamic component structural life tracking system, HeloTrack.net, which was developed for the US Navy to meet Condition Based Maintenance (CBM) objectives. Methods of fatigue lifing are discussed in the context of improving accuracy for end of life predictions of rotary wing fleets. TDA improves on the curren...

Radio frequency identification (RFID), The real-time location of objects and ability to track motion provide a wide range of useful applications in areas such as safety, security and supply chain. In recent years, radio frequency identification technology has moved from obscurity into mainstream applications that help speed the handling of manufactured goods and materials. RFID enables identifi...
