1. Retrieving cloud ice masses from geostationary images with neural networks
Sammanfattning : Clouds are essential to the Earth's energy budget and atmospheric circulation. Despite this, many cloud parameters are poorly known, including the mass of frozen hydrometeors. On the one hand, there will be specialized satellite missions targeting such hydrometeors. On the other hand, existing satellite data can be leveraged. LÄS MER
2. Advanced Analog MMICs for mm-wave Communication and Remote Sensing in 0.15µm mHEMT Technology
Sammanfattning : Multi-Gigabit per second wireless communication and atmospheric remote sensing for weather forecasts are new applications in the mm-wave frequency spectra. The High Electron Mobility Transistor is an excellent technology for high frequency mm-wave applications. Its low noise and linear performance makes a 0. LÄS MER
3. Guidance and Control for Multiple Spacecraft Formation
Sammanfattning : Multiple spacecraft formation forms a distributed space system where multiple spacecraft cooperatively exhibit the functionality of a single monolithic spacecraft or work in a cooperative way towards the completion of a common goal. This possibility of distributing the workload between different spacecraft provides the ability to work in parallel, enable economic and simple solutions in terms of spacecraft design, while is redundant towards partial or complete failure of a spacecraft.

4. Cross-Correlator Implementations Enabling Aperture Synthesis for Geostationary-Based Remote Sensing
Sammanfattning : An ever-increasing demand for weather prediction and high climate modelling accuracy drives the need for better atmospheric data collection. These demands include better spatial and temporal coverage of mainly humidity and temperature distributions in the atmosphere. LÄS MER
5. Interference Mitigation and Synchronization for Satellite Communications
Sammanfattning : Within this thesis, the satellite broadcast scenario of geostationary satellites is reviewed. The densely crowded geostationary arc in the common broadcast frequencies may create significant interference from adjacent satellites (ASI). LÄS MER
