  2. 1. Observing Sea Level Using Reflected Global Navigation Satellite System Signals

    Author : Johan Löfgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tide gauge; Global Navigation Satellite Systems; ocean tides; reflected signals; sea-level monitoring;

    Abstract : Sea-level rise due to global warming is predicted to have a large impact on human society, especially for populations living in coastal regions and on islands. It is therefore of great importance to monitor the sea level and to increase the understanding of the local hydrodynamic and meteorological responses to a global sea-level rise. READ MORE

  5. 3. Global Navigation Satellite Systems: Applications With Time Scales From Seconds to Decades

    Author : Tong Ning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; elevation dependent systematic effects; atmospheric integrated water vapour; Global Navigation Satellite Systems;

    Abstract : Global Navigation Satellite Systems (GNSS) can be used formany applications with time scales varying from seconds to decades.For~example, due to the ability of high-rate sampling, GNSStechniques are suitable for the detection of the large co-seismicdisplacements, which are dominated by low-frequency signals andtherefore can be recorded at a few Hertz and estimated with rathersmall uncertainty (millimetres).

  6. 4. Multi-Agent Mission Planning and Execution for Small Autonomous Underwater Vehicles

    Author : Özer Özkahraman; Petter Ögren; João Tasso de Figueiredo Borges de Sousa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underwater vehicles; collaborative; robotics; auv; navigation; coverage; search; slam; graph-slam; communication; control barrier functions; control; swarms; caging; capture; Datalogi; Computer Science;

    Abstract : Our planet is mostly covered in water, most of it still unexplored.In order to understand our environment better, oceanographers have been mapping and monitoring these waters using ship-mounted sensors and wired vehicles with limited range compared to the vastness of the oceans.

  7. 5. On Integrity Monitoring of Integrated Navigation Systems

    Author : Jan Palmqvist; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In civil aviation a new philosophy for flight safety and traffic management is under development. The goal is to enable an expected increase in air traffic density by reducing aircraft separation. The accuracy of the position estimate determined by the navigation system in each aircraft determines this separation. READ MORE
