From w.j.miloch at on 1 April 2013.

Position as postdoctoral research fellow (SKO 1352) in Plasma- and Space Physics is available at the Department of Physics, University of Oslo, Norway.

Application can be made online at: Application deadline 19. April 2013

The University of Oslo is searching for a physicist with a numerical modelling background, to calculate scintillations in GNSS signals due to in-situ observed F-region plasma irregularities by sounding rockets.

The announced position is associated with the group of plasma- and space physics and their STAR-initiative ("Space Technology And Research development centre") for a fixed period of 2 years. STAR is in charge of a sounding rocket program that takes advantage of the research infrastructure in Svalbard (optics, radars, GNSS scintillations) to study plasma waves, instability processes and turbulence in the F-region cusp/polar cap ionosphere. STAR also contributes to magnetospheric and planetary missions.

The STAR group developed a novel Langmuir probe system for the Investigation of Cusp Irregularities (ICI) series of rockets, to measure absolute electron densities down to meter scales. The instrument is miniaturized and will also be used on several cubesat missions to be in orbit in 2014-2015 (CubeSTAR and QB50). The main goal of the current project is to verify that real time measurements of F-region plasma structure irregularities may lead to determinations of the resulting position uncertainties for the GNSS users on ground. The main part of the project will be to develop a software model to calculate the amplitude and phase fluctuations in the received radio signals on ground, based on the rocket observations of F-region irregularities. During the project period we will have two rocket flights to test the predictions from the model with GNSS ranging errors observed on ground.

Applicants must have a Ph.D. in physics or equivalent experience in a relevant area (e.g. radio science, scientific use of GNSS receiver systems, classical theoretical background on wave propagation in an inhomogeneous medium, experience in phase screen techniques, or other relevant experience). The candidate must have demonstrated strong programming skills for advanced data analysis and visualization techniques. A good command of English is required.
