The Square Kilometre Array (SKA) project is an international effort to build the world’s largest and most sensitive radio telescope. Although the SKA mid-frequency telescopes in South Africa will be located in an Astronomy Geographic Advantage (AGA) Area, the effective management of radio frequency interference (RFI) in the protected radio quiet zone (RQZ) will be crucial to the success of the...
The report mainly discusses the measurement and calibration methods of large radio telescopes. The topic is related to the antenna's pointing, sub-reflector position and main reflector shape measurement and modeling methods. The SKA-P holography measurement is also disscussed detailly. The methods are adopted on several radio telescopes include CVN , and other 13m telescopes.
One of the major factors in resolving issues (from engineering design through commissioning to operations) is the time it takes to assimilate information and the ability to achieve a cohesive and coherent picture in order to find a solution. Information captured during project phases are not easily accessible to others, as very often information is siloed in different structures and systems...
