Warnant Dear Colleagues, The Royal Observatory of Belgium (ROB) opens 2 one-year post-doc positions for a research project on Galileo called GALOCAD. Background Since the sixties, the Royal Observatory of Belgium (http://www.observatoire.be) is involved in international research programs based on space geodetic techniques. In 1988, the ROB started a research program dedicated to the use of the Global Positioning System (GPS) for applications in Geodesy and in Geophysics. The use of GPS for high accuracy applications requires a careful modelling of all the error sources which can affect positions measured using GPS, in particular, atmospheric errors. This is the reason why a research project called "Effects of the Earth Atmosphere in Space Geodesy" has been created at ROB at the beginning of the nineties. The goal of this project is to assess and to mitigate atmospheric (tropospheric and ionospheric) effects on GNSS applications (http://www.gpsatm.oma.be). At the present time, a team of 5 scientist's and 1 technician is working on these topics. In 2004, the Royal Observatory of Belgium has submitted a proposal called GALOCAD in reply to Galileo Joint Undertaking call 2423. This proposal has been recently selected. GALOCAD stands for "Development of a Galileo Local Component for the nowcasting and forecasting of atmospheric disturbances affecting the integrity of high precision Galileo applications". The GALOCAD project At the present time, atmospheric variability due to the presence of small-scale structures in the neutral atmosphere water vapour or in the ionosphere Total Electron Content (TEC) can strongly affect the reliability of GNSS high accuracy real time applications. The concepts of reliability and integrity play a crucial role in the development of Galileo. Small-scale structures in water vapour and in TEC can be monitored using GNSS measurements. Nevertheless, up to now, the "density" of available GNSS stations in Europe was not sufficient to make a detailed study of the "local behaviour" of these atmospheric (ionospheric and tropospheric) structures. Since the end of 2003, Belgium is equipped with a network of 67 permanent GPS stations. The typical distance between the stations ranges from 7 to 25 km. The goal of our project is to use these data to perform a detailed study of atmospheric small-scale structures, to build a model of such representative small-scale activity, and to assess the influence of these structures on the reliability of Galileo precise positioning applications. In addition, the project will study the correlation which exists between small-scale ionospheric activity and geophysical parameters (like the local geomagnetic K index): the existence of a such correlation between small-scale structures and local K would allow to forecast the occurrence of degraded positioning conditions a few hours in advance based on K forecasts. The objective is to use the results of these investigations to develop and validate a prototype Galileo Local Component for the nowcasting and the forecasting of the effect of atmospheric disturbances on the integrity high precision Galileo applications. The project will start between June 01 and July 01 2006. Profile The ROB is looking for applicants having the following profiles : General profile : - Ph.
