  2. 6. On Optimisation and Design of Geodetic Networks

    Author : Mohammad Amin Alizadeh Khameneh; Mehdi Eshagh; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Optimisation of a geodetic network is performed to provide its pre-set quality requirements. Today, this procedure is almost run with the aid of developed analytical approaches, where the human intervention in the process cycle is limited to defining the criteria. READ MORE

  4. 7. Optimal Design in Geodetic GNSS-based Networks

    Author : Mohammad Amin Alizadeh Khameneh; Anna B. O. Jensen; Lars E. Sjöberg; Johan Vium Andersson; Terry Moore; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : An optimal design of a geodetic network helps the surveying engineers maximise the efficiency of the network. A number of pre-defined quality requirements, i.e. precision, reliability, and cost, of the network are fulfilled by performing an optimisation procedure. READ MORE

  5. 8. Detail Surveying with GPS

    Author : Kjell Almgren; Lars Sjöberg; []
    Keywords : ;

    Abstract : Abstract In the past ten years, the Global Positioning System (GPS) has revolutionized navigation and positioning at or near the surface of the Earth. Even though it is developed and authorized by the US military forces, it has found a remarkable civilian use. In most uses of GPS, the position accuracy is in the order of metres. READ MORE

  6. 9. Study on the Earth’s Surface Mass Variations using Satellite Gravimetry Observations

    Author : Hadi Amin; Mohammad Bagherbandi; Lars Sjöberg; Faramarz Nilfouroushan; Martin Horwath; Högskolan i Gävle; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geodetic reference system; geoid potential; global vertical datum; climate change; global warming; mass change; ice melting; sea-level change; remote sensing; satellite gravimetry; geodetiska referenssystem; geopotential; globala vertikala datum; klimatförändring; global uppvärmning; massförändring; issmältning; havsnivåförändring; fjärranalys; satellitgravimetri;

    Abstract : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.

  7. 10. A Complete Model for Displacement Monitoring Based on Undifferenced GPS Observations

    Author : Johan Vium Andersson; Lars Sjöberg; Milan Horemuz; Jan Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Undifferenced GPS observations; Real-time displacement monitoring; Early warning system; CUSUM; Surveying; Lantmäteri;

    Abstract : During recent years there has been a great focus on the climate changes within the media. More or less every day more newspaper articles are presented about the global warming issue and the effect on us human race. Climate models predict higher temperatures and more rain in the northern part of Europe. READ MORE
