Integrated Water Vapour mapping using vertical Wind Profiles

Water vapour in the atmosphere is a key variable in the prediction of heavy rain and thunderstorms. Water vapour in the atmosphere is still badly modeled although more and more ground based, airborne, as well as spaceborne measurements are retrieved. The main input for current water vapour maps are Integrated Water Vapour (IWV) measurements...

Superbus Positioning System: A High Accuracy Networked RTK GPS System

In this report a high accuracy positioning system is investigated for use in the Superbus. The Superbus project is an effort to apply a new and complete conceptual approach to public transport. It consists of a vehicle, logistics and infrastructure. The positioning system for the vehicle is to have a horizontal position error, which will not...

Fixed-Wing UAV Integrated Navigation with Low-Cost IMU/GPS

Today, there is an increase in the use of Unmanned Aerial Vehicles (UAV's), for applications that can be considered dull, dirty or dangerous when compared to those applications of conventional aircraft or helicopters. To further increase the use of UAV's, their navigation filters must be robust and reliable. The trend in current autopilot...

Accuracy Assesment of direct sensor orientation in UAV Photogrammetry

With the advent of Unmanned Aerial Vehicles, it becomes possible to use these vehicles to acquire photogrammetric images in a more cheap and flexible way compared with conventional photogrammetry from a full-sized airplane. A big factor in costs and resources in conventional photogrammetry is signalling and measuring ground control points, which...

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,...
