The physical configuration of the Transit satellites:
four solar panels charge the internal batteries and signals
are transmitted to the Earth by the "lampshade" antenna.
A stabilization boom ensures that the antenna is always
pointed downwards. The radio beacon emmissions (150 MHz)
of the satellites are used by the group to investigate
mid-latitude ionospheric scintillation causing irregularities.

The research conducted by this group is comprised of: the radio-satellite
study of ionospheric inhomogeneities, the global detection of
large scale gravity waves and ozone research.
Research by the group has been supported by a number of ARC grants over many years.
Extensive national and international collaborations have been maintained during this period.
Projects currently being undertaken include :
Scintillation Project
in collaboration with Communications Research Laboratories, Japan.
With the recent trend toward an holistic study of space weather, the group's efforts
are being extended toward servicing the requirement for a complete picture of the
mid-latitude ionosphere, particularly with respect to scintillation studies. As
part of a review of the literature available in this area, an extensive reference
list is being assembled. To view documents describing mid-latitude ionospheric scintillations, or peruse the list of
papers researched to date, please follow these links.
Warning: The construction of these pages is an on-going process.

Data that may be of interest
to collaborative partners or curious spectators has been made available
for examination. Some record files may be downloaded, others can be
examined in real-time or you are free to browse through the records
of observed passes for the NNSS satellites in the 1992 to 1996 period.
