Quality Assurance for High Spatial and Temporal Resolution Soil Moisture Data
In this experiment entangled photon pairs were created on La Palma, Spain. Then, one of these photons was sent to Tenerife, 144 km away. Additionally, random numbers were generated on both islands so that the way the correlations of the entangled photons were measured was independent of the photons. The spatial separation and timing of these actions was precisely arranged to show the counterintuitive nature of our world. Although this work does not completely rule out any "intuitive" theory it is the single most conclusive experiment of its type at the present time.
The aim of the QTS (Quantum Teleportation in Space) project was to bridge the gap between the laboratory setting of quantum teleportation and its future implementation in space.
Quantum entanglement (Erwin Schroedinger 1935) is one fundamental feature of quantum physics. It describes the situation, in which separate particles have only joint but no individual properties, independent from the distance from each other. This counterintuitive behaviour has led to a series of fascinating experiments.
QV Band Satellite System Optimisation
Is there a chance to achieve dm accuracy in positioning, just by means of an isolated single-frequency GNSS receiver? Which further external data has this isolated receiver to be provided with and within what time frame does the position determination converge to the requested accuracy? These are the crucial questions of Precise Point Positioning (PPP). In the project RA-PPP we show that there are several limiting factors to existing PPP algorithms and services, which rely on highly precise orbit and clock parameters.
This project aimed at the development of information products and service structures supporting critical decision-making processes in flood disaster management for the Austrian disaster relief organisations. Time-critical data and information generation are a major factor in successful disaster management.
RAyleigh Scattering as a tool to study the compactness of transiting small-mass ExoplaNets
Supporting REDD+ Activities and National Forest Inventories with Copernicus Satellite Data in Central and East Africa
The goal of this project is to develop a standardized procedure of merging potential synergistic combination of satellite data of the geostationary orbit and those of the low earth orbit which at first sight appear rather incompatible in terms of content, spatial and temporal availability.
Reflective Free-Space Laser Communication for Micro- and Nano-Satellites
Remote Sensing based Navigation in remote areas
The analysis of the electric field sensors on board the satellites of the Russian mission Resonance, which will be launched in the next decade, is the focus of this project. The aim of this mission is the investigation of wave-particle interactions and plasma dynamics in the inner magnetosphere of Earth, with the focus on phenomena occurring along the same magnetic field line and within the very same flux tube of the Earth's magnetic field. Amongst a variety of instruments and probes, several low- and high frequency electric and magnetic sensors will be on-board.
So called Radio Frequency Suitcases (RF-suitcases) are required for every spacecraft, in order to assure compatibility of the spacecraft and every groundstation delivering support to the mission. An RF-suitcase contains a simplified, yet representative configuration of the satellite flight hardware in order to make these tests representative.
Off-road navigation for robotic platforms
Robust optimization strategies for lightweight structures
The RONCALLI principle is based on linking centrally available information with current vehicle data. Key components from RONCALLI are GPS-positioning (later Galileo) and traffic relevant information from a central server which communicates with amobile device (PDA) over a GPRS connection. The permanent availability of positioning signals from satellites and efficient mobile radio connections form the central theme of the project.
The present activity supports RSA’s on-going GNSS receiver product development and aims at establishing real-time navigation algorithms, which enable the RSA receiver to reach a navigation performance in the range of one meter.
The overall goal of the RT-PPP project, was to develop PPP techniques suitable for various real-time or near real-time applications. The main focus was placed on the production of real-time clock, orbit and atmospheric corrections as well as their transmission via Ntrip to a user client.
