Dr Phil MjwaraDirector GeneralDepartment of Science and TechnologyRepublic of South Africa
Outline
• Multi-wavelength Astronomy
• Purpose of the AGA Bill
• The process to date
• Example of Astronomy Advantage Areas
• AGA Bill impact on broadcasting and telecommunications
• Continuing stakeholders consultations
Multi-Wavelength Research
• Southern African Large Telescope – Northern Cape, RSA• High Energy Stereoscopic System – Namibia• Karoo Array Telescope/SKA – Northern Cape, RSA
SKASALTHESS
The Electromagnetic spectrum
Increasing Energy or Frequency
AGA Bill: The Purpose
• Protect Astronomy investments already made in South Africa
• Maintain an environment for a global astronomy hub that will continue to attract international investments
• Create a competitive edge for South Africa to win the bid to host the SKA
• Attract Astronomy investments which may include C-BASS (C-Band All-Sky Survey) and DSN (Deep Space Network) Array
• AGA Bill presented to Cabinet in Nov 2005 and approved for a public consultation process
• Consultations started in early 2006 with stakeholders
• Amendments to the AGA Bill presented to Cabinet in Nov 2006 and approved for tabling to Parliament
• Presentation of the AGA Bill to the S&T Portfolio Committee
• Public hearings
AGA Bill: The Process
• Further amendments presented to the S&T Portfolio Committee
• Adoption of the AGA Bill by the S&T Portfolio Committee
• Presentation of the AGA Bill by S&T Minister to the National Assembly
• Approval of the AGA Bill by the National Assembly and Bill referred to the NCOP
AGA Bill: The Process
Astronomy Advantage Areas
CORDINATED ADVANTAGE AREAS
• Regulate the area(s) as buffer zones for the protection of Central and core advantage areas
CENTRAL ADVANTAGE AREAS
• To protect the core from immediate surroundings negative interference on astronomy devices
CORE ADVANTAGE AREAS
• Where an astronomy device is located or may be situated in future
SKA sites
SKA Astronomy Advantage Areas
• Co-ordination zone Established to prevent high powered broadcast transmitters from negatively impacting the core zone
● FM not affected in all areas
● Single channel analogue television transmissions with high power and from high sites
i. Effectively replaced with multi-channel low power municipal relay transmitters
ii. Will be migrated to digital technology (low power local transmissions)
iii. All broadcasting services are available from satellite (already digital)
● Point-to-point and point-to-multipoint telecommunication stations for public and private communication systems
i. Re-engineering can be done to reduce interference in the direction of the radio astronomy instrument
