Exploration of the Solar System
with VLBI radio telescopes

UTAS radio telescopes have been used for a number of space projects to track, monitor and study the signals propagated by spacecraft. From the landing of Huygens on the moon Titan, to scintillation studies of the solar wind with Venus and Mars Express, tracking support of Lunar missions, orbit determination of Radio Astron space antenna, to launch and re-entry maneuvers of rockets in Earth orbit.

radio telescopes

UTas operates five radio telescopes distributed around the Australian continent. The antennae are used daily for a number of astronomical, geodetic and spacecraft tracking purposes. All radio telescopes are operated remotely from the control room in Hobart.

space missions

Spacecraft observations for
deep space exploration

Spacecraft as a target for radio observations are used to study a broad range of scientific phenomena in our solar system and to enhace space missions with additional ground-support.

The University of Tasmania is expanding its tracking capabilities and satellite communications with the construction of two new antennas to provide ground-support (TTC and downlink capabilities) to Earth-orbiting satellites. The installation of the 7.3 metre (in S-,X- and Ku-band) is well on-time on 2021.
