  1. 1. A study of the possibility to connect local levelling networks to the Swedish height system RH 2000 using GNSS

    University essay from Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Ke Liu; [2011]
    Keywords : GNSS; GPS; levelling; RH 2000;

    Abstract : In this study, the connection of a local levelling network to the national height system in Sweden, RH 2000, with GNSS-techniques is investigated. The SWEN 08 is applied as geoid model. Essentially, the method is precise normal height determination with GNSS. READ MORE

  3. 2. Determination of a gravimetric geoid model of Kazakhstan using the KTH-method

    University essay from KTH/Geodesi och geoinformatik

    Author : Daniya Inerbayeva (Shoganbekova); [2010]
    Keywords : geoid model; least-squares modification of Stokes’ formula; the KTH-method; GPS Levelling; Kazakhstan;

    Abstract : This study work deals with the determination of the gravimetric geoid model for Kazakhstan by using the KTH-method. A number of data sets were collected for this work, such as the gravity anomalies, high-resolution Digital Elevation Model (DEM), Global Geopotential Models (GGMs) and GPS/Levelling data. READ MORE

  4. 3. Determination of a gravimetric geoid model of Sudan using the KTH method

    University essay from KTH/Geodesi och satellitpositionering

    Author : Ahmed Abdalla; [2009]
    Keywords : ;

    Abstract : The main objective of this study is to compute a new gravimetric geoid model of Sudan using the KTH method based on modification of Stokes’ formula for geoid determination. The modified Stokes’ formula combines regional terrestrial gravity with long-wavelength gravity information provided by the global gravitational model (GGM). READ MORE

  5. 4. Determination of a gravimetric geoid model of Greece using the method of KTH

    University essay from KTH/Geodesi och satellitpositionering

    Author : IIias Daras; [2008]
    Keywords : ;

    Abstract : The main purpose of this study is to compute a gravimetric geoid model of Greeceusing the least squares modification method developed at KTH. In regional gravimetricgeoid determination, the modified Stokes’s formula that combines local terrestrial datawith a global geopotential model is often used nowadays. READ MORE

  6. 5. Corrective Surfacefor GPS-levelling in Moldova

    University essay from KTH/Geodesi och satellitpositionering

    Author : Uliana Danila; [2006]
    Keywords : ;

    Abstract : The main objective of this thesis is the construction of a corrective surface in theMoldova area for further conversion of the geodetic heights into normal heights. For thispurpose a detailed analysis of the optimal combination of heterogeneous height data ispresented, with particular emphasis on (i) modeling systematic errors and datuminconsistencies, (ii) separation of random errors and estimation of variance componentsfor each height type, and (iii) practical considerations for modernizing vertical controlsystems.
