JOANNEUM RESEARCH is Austria’s second largest private research organisation and it is owned by the Province of Styria (20%) and TNO (10%) . 15 research units are organised in five division: Sustainability and Environment, Information Technology, Electronics and Sensor Technology, Materials and Processing, Economy and Technology, Medical Technology.

Joanneum Research participated in about 50 projects in the 5th EU Framework Programme. So far about 6 projects have been accepted within FP6, two of them as a coordinator.

Key figures (2002/2003):
Staff 361 
Revenues 27,8 M€
Basic subsidy 7,8 M€

The work proposed for this project will be carried out by our Institute of Applied Systems Technology, that has a strong background in satellite and terrestrial broadband communications, radar technology, navigation and wave propagation.

JOANNEUM RESEARCH’s background relevant for the proposed activity Prime contractor for a ESA/ESTEC project on the measurement and modelling of multipath effects of SatNav signals during landing approach and landing of aircrafts under instrument landing conditions.

Measurements were carried out using a wide band, directional channel sounder on an experimental jet.A second, parallel flying, aircraft that carried the transmitter unit acted as a satellite simulator. Measured data were analysed and modelled resulting in deterministic and statistical channel models. (‘Navigation Signal Measurement Campaign for Critical Environments’; ESTEC Contract No. 16059/02/NL/DS) Within the frame of the ESA/ESTEC Contract ‘Galileo Interference Measurement Campaign’, Joanneum Research has developed a highly sensitive mobile measurement equipment for the measurement and the high speed recording of interfering signals in the frequency range of 1 to 2 GHz.

This equipment was used by JOANNEUM to conduct a European wide measurement campaign covering more than 3000 km en-route measurements with a special emphasis on the most important user scenarios (airports, harbours, railway stations, .... ). In a second step the data were analysed and classified for each of Galileo’s assigned frequency bands.

Further to mention are the ESA/ESTEC contracts ‘ Characterisation of the GNSS-land mobile propagation environments’, ‘Equipment for wide-band airborne multi visibility assessment’, ‘Land mobile satellite narrowband propagation campaign at Ka-band’ and the project on ‘Service quality assessment for Ka-band satellite personal communications’.

The main focus in the first project was the development of a simulation tool that allows the combined assessment of the ionos- and tropospheric propagation conditions in combination with environmental effects and various multi-satellite constellations. In the later projects the emphasis was on the investigation of shadowing and blockage effects and on the analysis and effect of possible countermeasures.
