A Signal Simulation Facility for GNSS Receiver Design and Testing. The proposed Facility comprises a Global Navigation Satellite System (GNSS) RF Signal Simulator which allows laboratory testing of new signal tracking and navigation solution algorithms, under different scenarios. Simulation of the operation of current and future GPS satellites, and of the new European GNSS "Galileo", is vital for testing new receiver designs.

The proposed Facility comprises a Global Navigation Satellite System (GNSS) RF Signal Simulator which allows laboratory testing of new signal tracking and navigation solution algorithms, under different scenarios. Simulation of the operation of current and future GPS satellites, and of the new European GNSS "Galileo", is vital for testing new receiver designs. For example, the Facility could be programmed to generate a GPS satellite signal with user-selectable physical variations in the signal path, including the presence of RF jamming sources, high atmospheric disturbances, diffraction effects and multipath. As many of the signal variations are rare and/or unpredictable, the Signal Simulator is the only means to carry out such tests.Read moreRead less
CHAMP GPS-Altimetry. The proposed research project aims to develop a novel application for the Global Positioning System (GPS), namely the use of GPS signals reflected from sea- or ice-surfaces and received by Low-Earth-Orbiter (LEO) for determination of these surface heights. Data from the German satellite CHAMP will be used for this purpose, for selected regions in Antartica. CHAMP covers areas not visited by other remote sensing satellites. The Fellow is instrumental for obtaining and process ....CHAMP GPS-Altimetry.

The GPS receiving system consists of one or more signal detection components with antennas, as well as a processing device. The main objectives of the research are: the estimation of the power budget, developing techniques for system modelling, developing techniques for simultaneous reception of signals from different satellites, and processing these signals with the aim of improving the spatial resolution, development of a demonstrator system, and evaluation of the system for selected remote sensing tasks.

The development of new techniques for partial discharge monitoring and location in high voltage underground power cables. Increased utilization factors have caused a significant increase in the loading of high voltage distribution cables. This increased loading subjects cable insulation to increased stress which can degrade the insulation, cause cable failure and power loss to consumers. On-line cable insulation monitoring is required and partial discharge monitoring in cables provides a viable ....The development of new techniques for partial discharge monitoring and location in high voltage underground power cables. Increased utilization factors have caused a significant increase in the loading of high voltage distribution cables. This increased loading subjects cable insulation to increased stress which can degrade the insulation, cause cable failure and power loss to consumers. On-line cable insulation monitoring is required and partial discharge monitoring in cables provides a viable technique, but technical problems have prevented its application in on-line operation.
This project will develop techniques for such on-line monitoring. High frequency electrical sensors will be used to reduce interference and improve signal levels. Both a coarse alarm and a higher sensitivity monitor will be developed.

Guaranteeing the safety of short welds in automotive applications. Most safety-critical welds in the automotive and related industries are of short duration (less than three seconds). We will develop a unified theoretical model of short welds which accounts for all important phenomena. Using this model, we will create the first system to check every safety-critical weld in real time, with 3D data objects that use all the data available from the non-stationary process. The outcomes will be a comp ....Guaranteeing the safety of short welds in automotive applications.
