1. Undifferenced GPS for Deformation Monitoring
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
2. Escaping 'death by GPS' : foundations for adaptive navigation assistance
Sammanfattning : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. LÄS MER
3. Quality description in GPS precise point positioning
Sammanfattning : GPS processing, like every processing method for geodetic applications, relies upon least-squares estimation. Quality measures must be defined to assure that the estimates are close to reality. LÄS MER
4. GPS : superficial observations for deeper knowledge of the earth
Sammanfattning : .... LÄS MER
5. Description and Analysis of Data and Errors in GPS Meteorology
Sammanfattning : This report presents the relation between remote sensing techniques used for estimation of atmospheric water vapor content, and numerical weather prediction. The thesis makes an overview of the methods for estimation of the zenith wet/total delay (ZWD/ZTD) for radio waves in the neutral atmosphere, and a statistical description of data in relation to the sampling problem for atmospheric water vapor.
