Australian Centre for Remote Sensing announces reduction in ERS SAR prices

SHARE

Australia, 20 December 2006 – The Australian Centre for Remote Sensing (ACRES) has announced a major price reduction in Synthetic Aperture Radar (SAR) products from the Earth Resource Satellite (ERS).

Prices have been reduced from over $2000 down to $590 as a result of ACRES being granted greater pricing flexibility by the satellite operator. The reduced price will increase the attractiveness and utilisation of ERS SAR data to a wide range of users.

For a small fee, customers may also place requests for the ERS satellite to acquire data over a particular area in the future. ERS SAR products have been available from ACRES since 1993. A major advantage of SAR data is its ability to image the Earth through cloud or at night. C-band SAR data is particularly useful in coastal and ocean environments where it has been successfully used in helping to identify oil seeps and slicks, and ship detection.

ACRES holds a large and comprehensive archive of ERS SAR data over Australia and New Zealand, including complete continental coverages from the ERS-1 and ERS-2 tandem mission undertaken for nine months in 1995-96.

During the tandem mission, the orbit configuration of ERS-1 and ERS-2 enabled global observations, one day apart, from the ERS-1 and ERS-2 satellites. Data acquired during the period of the tandem mission is particularly suited for interferometric applications, including Digital Elevation Model (DEM) generation. The ERS-1 and ERS-2 SAR data may also be used for time series studies with the currently available Envisat ASAR data.

– About ERS-1 and ERS-2
The first satellite in this series, ERS-1 was launched on 17 July 1991 and ERS-2 on 20 April 1995. These satellites are designed to gather information about the earth’s ocean, ice and land resources using a variety of sensors. Orbiting the Earth for nine years, over three times its planned lifetime, the ERS-1 mission was ended on 10 March 2000 by a failure in the on-board attitude control system.

ERS-2 is a notable European engineering achievement, reaching the milestone of 10 years in orbit on 21 April 2005 with all instruments working and providing excellent data. Over the 10-year period, the satellite has underpinned and supported the development of unique know-how, a broad range of outstanding Earth Observation science results and a range of operational applications.
