X – azimuthal (East-West) Z – radial (outwards)

FedSat Coordinates

• Australia’s first satellite in 35 years

• Built by Cooperative Research Centre for Satellite Systems (CRCSS)

• 58kg micro satellite (approx 50cm cube), three-axis stabilised and with 2.5m deployable boom

• Scientific and communications experiments

• Launched by NASDA in H-IIA rocket in December 2002

• In a low Earth circular polar orbit, sun synchronous at 10:30 LT, an inclination of 98.7º and a period of ~101 min

Newmag magnetometer payload

• Triaxial fluxgate magnetometer• Built in collaboration with IGPP/UCLA• Mounted on 2.5m boom to minimise interference from the spacecraft platform and other payloads• Burst mode sampling rate of 100 vector samples/second (nominally 10VS/s)•Quicklook data http://www.ips.gov.au/World_Data_Centre/1/5

Concept:•2 radars •with intersecting beams.

Advantages:

• Lower latitude coverage than other SuperDARN radars

• Provides essential longitude coverage for mapping convection in Southern Hemisphere

Radio astronomyASKAP: Australian SKA Pathfinderhttp://www.atnf.csiro.au/projects/askap/science.html ASKAP is designed as a survey instrument: 700-1800 MHz, field of view of 30 square degrees, cover the sky ten times faster than any current telescope.Primarily an astronomy instrument .

MWA : Murchison Wide-field Arrayhttp://www.haystack.mit.edu/ast/arrays/mwa/

MWA is: an array of 500 tiles Operating frequency range of 80 to 300 MHz An astronomical instrument with a solar
