Ionospheric errors in GPS: Measuring and modelling the ionospheric delay using single and dual frequency receivers

Accurate weather forecasting plays an important role in predicting precipitation events. With the warming climate the precipitable water vapour in the atmospheric is increasing. Since weather parameters as precipitable water vapor have a high spatial variability, interpolation of water vapor data over an area of hundreds of kilometer does not...

Ionospheric monitoring using GNSS data from LEO satellites for space weather applications: (additional thesis)

In this report, a least-squares approach is described for retrieving the 3D structure of the electron concentration in the Earth’s upper ionosphere and plasmasphere, using Global Navigation Satellite System (GNSS) data-sets from Low-Earth-Orbiting (LEO) satellites. Due to the lack of horizontal radio wave geometries, the method uses assumptions...

Precipitable water vapour estimation using GPS in Uganda: Measuring and modelling the precipitable water vapour using single and dual frequency GPS receivers

Additional thesis - Precipitation and especially rainfall are very important for the world’s population. It has its positive and negative side like providing water and contrary causing floods. Therefore it is of utmost importance to make clear and accurate weather predictions. The revolution of GPS in the last few decades gave a new opportunity...

Precipitable water vapour estimation using GPS in Uganda: A study on obtaining the Zenith Wet Delay

Additional thesis - To improve weather monitoring, local near-real time weather forecasts and climate monitoring, a dense network of sensors should be set up. As shown already in the 1990s, GPS is a promising measurement device to form a dense network for meteorology observation. Because of economic reasons, a network of dual frequency GPS...

Novel techniques for coastal monitoring: A case study near Monster-Ter Heijde

There are currently three active projects under development for the Delfland coast, all aiming at reinforcing the coast. The main issue is where to put the sand such that it arrives at the coast in the best place, without causing any damage to e.g. the new nature development. To answer this question, knowledge about sand transport is necessary,...
