The Research Project

Under contract with Geoscience Australia, UTAS operates a continental-wide network of geodetic Very Long Baseline Interferometry (VLBI) telescopes. Our antennas in Katherine (NT), Yarragadee (WA) and Hobart (TAS) contribute to measuring global reference frames and Earth orientation such as polar motion and the rotational speed of the Earth.

The next generation VLBI Global Observing System (VGOS), comprising new broadband receivers is expected to improve the current measurement precision from the centimetre level to a few millimetres or better.

The main research goal is the improvement of the current precision of Australian VLBI sessions from about one centimetre to the millimetre level. While the successful candidate is expected to pursue her/his independent research, testing new modes, optimising the allocated frequency bands and developing new correlation and fringe-fitting procedures are possible areas of research.The successful candidate will support the implementation of the VGOS system for the AuScope VLBI antennas and conduct Australian VGOS observations.

This project includes a lot of technical work, hence the candidate should not be afraid of using new programs. The candidate will further have an opportunity to actively test the solutions they identify through taking an active role in supporting the AuScope operations.


The following eligibility criteria apply to this project:

  • The project is open to domestic (Australian and New Zealand) and international candidates
  • The Research Higher Degree must be undertaken on a full-time basis
  • Applicants must already have been awarded a Masters degree or First Class Honours degree or hold equivalent qualifications or relevant and substantial research experience in an appropriate sector
  • A good level of spoken and written English is necessary for this project

Candidates from a variety of disciplinary backgrounds are encouraged to apply. Knowledge and skills that will be ranked highly include:

  • Education in geodesy and spatial sciences - familiarity with space geodetic techniques is welcome
  • Education in Physics or Astronomy
  • Experience with Linux and software development
  • Signal processing
