SAR images from ERS, JERS and RADARSAT processed at Tromso Satellite Station since 1993

Tromso Satellite Station is equipped with one of the world's fastest
processing and distribution system for ERS-1 SAR data. The ERS-1 SAR
processor is based on a parallel processing concept and is developed
and produced in Norway. A similar, but not as powerful, processor is
used for JERS-1 SAR processing on a contract with ESA. The Norwegian
developed broad band distribution system, NORSAT-B (2 Mb/s), gives TSS
a unique and flexible distribution capacity for full resolution SAR
images.

TSS offers a SAR full resolution image, a SAR low resolution image,
and a SAR low resolution calibrated image from the ERS-1 SAR
sensor. These images cover areas of 100x100 km and are produced within
8 minutes after acquisition. In agreement with ESA/NASDA the same
products based on the JERS-1 SAR sensor will be offered. The JERS-1
products cover an area of 75x75 km and are available approx. 20
minutes after data acquisition.

Through the Norwegian national ERS-1 programme, the ERS-1 SAR data has been
demonstrated to be most useful for several near real-time applications:

* ice monitoring
* ship detection
* oil spill detection
* weather and wave forecast
* autumn ploughing

TSS will continue the operations on the ERS-2 satellite when data from that
satellite becomes available during Spring 1995.

All ERS-1 SAR images processed are available for ordering from archive.
