## Fedsat – An Australian Research Satellite (deceased)

-  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

_**Above:**_ Launch of the NASDA H-IIA rocket carrying Fedsat into orbit, 14 December, 2002.

## TIGER: Tasman International Geospace  Environment Radar

**TIGER: **_**T**_asman _**I**_nternational _**G**_eospace  _**E**_nvironment _**R**_adar

_**Concept:**_
- 2 radars
- with intersecting beams.
**      **

_**Advantages**__:__ _
-  Lower latitude coverage than    other SuperDARN radars
-  Provides essential longitude     coverage for mapping convection     in Southern Hemisphere

## Cosmic Ray Program

_**Equipment**_
- Multi-directional surface and underground muon telescopes (Mawson, 73 S mag and Hobart, 51.6o S mag)
- Collaborative array with Japan, Brazil, Germany monitoring space environment variations

_**Scientific Program**_
- Magnetic storm precursor identification
- CME shock strength and geometry via collaborating high and low energy monitor arrays

## Australian Monitoring network

**Australian Monitoring network**

- Network of sites
- Australian mainland
- Antarctic Territory
- PNG and Pacific Norfolk Is., Niue, and soon Cocos Is.
- New Zealand
- Low-High latitudes
- 150E & 120E long. chains
- Area covered
- (110E-170W, 0-70S geog.)

## Slide 12

## Earth Station Downlink Availability

- Aust. Remote Sensing Centre (ACRES) Alice Springs (9m X/S-, 5m X-band dishes)
- TERSS (9m X-band Landsat 7) Hobart
- Note: not verified recently.

## Radio astronomy

_**ASKAP**_**: ****Australian SKA Pathfinder**
- http://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 Array**
- http://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 component - SHI.
**SHI = **Solar-Heliospheric-Ionospheric Science
- Interplanetary Scintillation
