- Still in design process but not everything finalised
- Square Kilometre Array
- Dense core, spread out arms
- Across Aus and South Africa
- different antenna cover different frequencies
- Main goals of array:
- Galaxy Evolution, Cosmology and Dark energy
- The first billion years of the Universe
- Strong field tests of gravity using pulsars and black holes
- Cosmic Magnetism
- Cradle of life – complex molecules around distant stars
- Interferometer – Very heavy proccessing required
- Lots of data coming in, lots to be archived
- MWA ( approx 1% of the size of the SKA)
- 7km of trenching
- 10kn of electrical cable
- 16km of fibre
- 2048 dual pole antennas
- 42 km of coax cable
- Way too dense information for me to summarise
- Next Generation Archiving System
- Distrubuted, forwards data to various clusters around the world
- Users can subscribe to tags
- Meteoroid (in space), Meteor (in atmosphere) , Meteorite (on earth)
- Observed from 2 or more locations. 120-30km above surface. Freefall below 30-40km
- Triangulation, analysis, weather model (can move up to 10km sidewise)
- Search trip
- Meteorite!
- Types: Stoney, Achondrite, stony-Iron, Iron
- History
- Manually operated film cameras (since 1959)
- Automated film cameras (first in 1997, since 2001)
- Digital cameras (ideas and dev since 2010, operation since 2013)
- First Meteorite observed, triangulated and found in Czech republic in April 1959
- Since 2009 15 automated film cameras across 13 stations in Europe
- Nullarbor network of automated film cameras – 3 stations 2005, 4 stations since 2007
- Based on Industrial PC
- Old ones P1 , newer P3
- Microphone picks up sound from meteor going through atmosphere
- Software
- Using Redhat 7.3 (released 2002)
- ntpd sync’d
- New System using Centos 5.2
- Digital Cameras
- Triggered system
- sequence of hi-speed HR images fired when event detected
- 11 images/second
- Complicated design so put aside for now
- Long exposure system
- MK-I – 2 built as testbed
- eBox Pc, 933Mhz, 3xUSB, 1TB HDD, DSLR taking 30s exposures, leo stick uController for power, GPS and camera control, 3G modem, 2x2TB NAS
- 3G modem lockups
- Slow CPU
- SD card unrelaible
- External HDD a worry
- MK-II – 10 built, 5 deployed, 60 planned across Australia + USA
- Industrial PC
- Video Camera
- Atom N2600 dual core 1.6GHz
- 480G SSD
- 2 X 4TB external HDs
- Kit camera system for enthusiasts
- Similar to long-exposure system, possibly lower resolution
- Goal 60 Cameras, cover 1/3 of Australia. See 15-20 meteorites / year in searchable areas, 500TB data per year
- Data available for other uses?
