   Författare :Johan Vium Andersson; Lars Sjöberg; Jonas Ågren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : deformation monitoring; GPS; modified NGS-parameters; undifferenced GPS-observations; Kalman filter; Geoengineering; Geoteknik;

   Sammanfattning : This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. LÄS MER

3. 2. A Complete Model for Displacement Monitoring Based on Undifferenced GPS Observations

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
