The MRT was primarily designed to make a survey with a point source sensitivity of 150 mJy.

The North-South arm is built along the old Port Louis to Flacq railway line which closed in 1964.

Linux systems using custom software transform these correlated signals into raw images called "dirty maps".

Data is collected as the trolleys in the North-South arm move southward from the array centre.

Also, the non-co-planarity of the East-West arm have led to new imaging techniques used in cleaning the raw data.

The group outputs are added together, with a tracking capability of about 2 degrees for a source transiting at meridian.
