3.0 milliradians and the field of view is 45 degrees from
nadir.
The system has full radiometric calibration. Variations
in aircraft roll, pitch and yaw are corrected by sample
timing for roll, and inertially stabilised integral mount
for pitch and yaw. The scanner can operate at speeds up
to 300 knots depending on altitude above ground.
Typical area coverage per day can be as high as 8000
square km.

2. SATELLITE DATA RECORDING
The Australian Landsat Receiving Station in Alice Springs
managed by the Australian Centre for Remote Sensing
(ACRES) routinely receives data from Landsat 5, SPOT, and
ERS-1 SAR systems and will be able to receive data from
JERS-1 SAR and Radarsat when data becomes available.
The data is distributed through the ACRES facilities in
Canberra. An additional ground receiving station is
scheduled for installation in Hobart, Tasmania, in late 1992.
A British Aerospace Australia fast delivery processor will be
installed in the near future by ACRES to provide a SAR
processing facility for customers.

A new low cost NOAA Satellite Receiving System has been
developed by Pikeville Pty Ltd in collaboration with the
Centre for Remote Sensing, University of New South Wales
and the New South Wales State Government. The system
has an especially designed azimuth and altitude tracking
mechanism, supported by sophisticated software that allows
automatic and continuous 360° tracking of the satellite, and
links directly to an IBM or IBM compatible personal
computer. Data can be immediately viewed in image format
or transferred via Exabyte tape to any other image analysis
sen The cost of the system is approximately $US

The Department of Lands in Queensland participated in the
OEEPE SPOT triangulation study of 4 SPOT scenes. The
adjustment model developed made use of recorded auxiliary
data of satellite position and attitude. The results demonstrated
that triangulation is an effective means of minimising the
number of ground control points required for the adjustment
With a minimum impact on geometric accuracy.
3. GPS AIRCRAFT POSITIONING
À numbèr of organisations in Australia have been
experimenting with the installation of GPS receivers in the
101
aircraft during photography to determine its position. These
organisations include the Royal Australian Army Survey
Corps, Australian Aerial Mapping together with the
Queensland Department of Lands and AUSLIG. Preliminary
results by the Army indicate that the aircraft positions can be
determined with accuracies of less than 1m.

1. DEVELOPMENTS IN STEREOPLOTTER
EQUIPMENT
There are three companies producing Photogrammetric
Systems in Australia.
(i) Qasco Analytical Systems
PO Box 233 Baulkham Hills. N.S.W 2153
Telephone:+61 2 639 8822
Facsimile:+61 2 686 2620
Qasco Analytical Systems is committed to the
development of simple, cost effective digital mapping
Systems. Products include digital encoder interface
systems and software as well as the rapidly expanding
range of PC based kits for converting analogue plotters
to full analytical systems.
The Qasco range of conversion kits was introduced at
Kyoto in 1988 and now includes kits for Wild B8, Wild
B8S, Santoni IIC, Zeiss Topocart, Kern PG2, and
Wild A10 instruments.
The most recent development is a kit to enable existing
analytical plotters such as Wild BC1, BC2 and the Zeiss
Planicomp series to be upgraded to PC based operation.
(ii) ADAM Technology

In the past four years ADAM has made significant
progress in all aspects of its photogrammetric systems.
ADAM works closely with several Australian
Universities and now supports the foundation of a chair
in Photogrammetry at Newcastle University. As well as
the standard simultaneous bundle solution, research
grants have resulted in three alternative orientation
methods being offered to users. These are; a two-stage
coplanarity solution for large-format users; a reduced
normal equation collinearity solution for both terrestrial
and aerial; and an incomplete datum solution for close-
range terrestrial work. New versions of the standard
system software have been released regularly, and the
product range has increased to include analog-to-
analytical conversions for PG2, Topocart and B8
instruments.
The MPS-2 has been improved through changes to
chassis design (for added stability) lighting, optics and
motor-control firmware.
Significant improvements to the ASP2000 have
increased its performance to first-order standards with a
repeatability of 2-5 micrometres now readily achievable.
The optical system has been steadily enhanced and now
includes fixed power oculars of 10x, 20x and 33x and
10-20x differential zoom as cost options. Its electronics
system is currently being upgraded to utilise the 1386
chip set.
By early 1992 all ADAM systems will use this common
"Core-processor" design based on a single CPU and
math co-processor. This will enable higher
transformation rates, better communication and a wider
range of peripherals on the stereo-plotter. In addition,
