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.

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,
