Regulations

Protection of the Karoo Central Astronomy Advantage Areas in terms of the Astronomy Geographic Advantage Act, 2007

Schedule D-Regulations restricting interference due to electrical activities within the Karoo central astronomy advantage area 1

(1) The map on the next page depicts the 20-km radius circle around the SKA Virtual Centre, within which approximately 173 SKA radio astronomy stations will be located as well as their protection corridors. The map also depicts the protection corridors along the three spiral arms required for approximately 24 SKA radio astronomy stations located within the Karoo Central Astronomy Advantage Area 1.

[Annexure A to Schedule D (paragraph 1) substituted by section 4 of Notice No. 4726, GG50527, dated 17 April 2024]

 

(2) Although the geographical area referred to is that related to the declared Karoo Central Astronomy Advantage Area 1, to define the SKA radio astronomy stations involved, the radio frequency interference to be restricted is that occurring in the whole of the radio frequency spectrum from 100 MHz to 25.5 GHz.

 

(3) A smaller scale version of the map on the next page and/or a GIS-shape file is available on request from the management authority. The perimeters of the corridors are 5 km distant on either side of the spiral arms.

 

(4) Applicants for a permit, who are determining radio frequency interference levels in terms of regulation 5, and required separation distances in terms of regulation 6 of these Schedule D Regulations, may request the management authority to provide the applicable geographical location on the periphery of the protection corridors or on the 20-km circle around the SKA Virtual Centre for the electromagnetic emissions under consideration.
