  2. 1. Geoid Model of Tanzania from Sparse and Varying Gravity Data Density by the KTH method

    Author : Prosper Ulotu; Lars Sjöberg; Hossein Nahavandchi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geoid; sparse gravity data; gravity database; GGM validation by gravity; corrector surface; hybrid geoid; KTH-LSMS with AC; Mt. Kilimanjaro; Tanzania.; Earth sciences; Geovetenskap;

    Abstract : Developed countries are striving to achieve a cm geoid model. Most developing countries/regions think that the situation in their areas does not allow even a few decimetre geoid model. GNSS, which provides us with position, is one of the greatest achievements of the present time. READ MORE

  4. 2. Mold2012 : a new gravimetric quasigeoid model over Moldova

    Author : Uliana Danila; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geoid; quasigeoid; KTH method; corrective surface;

    Abstract : In order to be able to use the operational Moldavian GNSS Positioning System MOLDPOS efficiently for the determination of normal heights in surveying engineering, e.g. during the construction of a road, an accurate quasigeoid model is needed. READ MORE

  5. 3. Height determination by GPS : A practical experiment in central Sweden

    Author : Stig-Göran Mårtensson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Division of Geodesy Reports; Surveying; Lantmäteri;

    Abstract : GPS as a height measuring tool has been widely introduced for solving various tasks within the fields of Geodesy and Engineering Surveying. The obvious advantage of not needing lines of sight when acquiring height differences is, however, darkened by the fact that GPS and traditional spirit levelling have fundamentally different reference systems for heights.
