6. Analysis of Temporal and Spatial Variations in Atmospheric Water Vapor Using Microwave Radiometry
Sammanfattning : The amount of atmospheric water vapor is highly variable in both time and space. In this thesis some aspects of the variations in the atmospheric water vapor are treated. LÄS MER
7. Studies of Atmospheric Water Vapor Using the Global Positioning System
Sammanfattning : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. LÄS MER
8. A study of precise position measurements using space geodetic systems
Sammanfattning : .... LÄS MER
9. Modern numerical methods in electromagnetics applied to the design of reflector antennas and horn feeds
Sammanfattning : .... LÄS MER
10. Space Geodesy Techniques: An Experimental and Theoretical Study of Antenna Related Error Sources
Sammanfattning : This thesis presents work associated with antenna related error sources, as well as antenna design, in space geodesy utilizing the techniques of Very-Long-Baseline Interferometry (VLBI) and the Global Positioning System (GPS). Geodetic VLBI uses large radio telescopes, often in global networks observing at least a few times per year. LÄS MER
