The aim of this project is to contribute to the development of the frequency synchronisation system for the Square Kilometre Array (SKA) radio telescope.

The SKA will be the largest and most complex astronomical instrument to date, with individual antennas spread over continental scales. One of the most complex technical challenges will be the coherent combination of astronomical signals collected by the hundreds of remote antennas. To achieve this, astronomical observations must be synchronised using timing signals of exquisite accuracy and precision.

The student will work as part of the international SKA consortium for ‘Synchronisation and Data Transport (SaDT)’ to help design, build, and test an optical fibre-based frequency distribution system tailored to meet the scientific needs and logistical challenges of the SKA. This system will be developed in in our UWA laboratory, tested on Perth’s iVEC and AARNet fibre networks, with the view to deploy the system on the MeerKAT telescope in South Africa. This research will be conducted in collaboration with the SKA Signal and Data Transport Consortium and SKA South Africa.
