TerraSAR-X satellite data, available to SOCET SET® and SOCET GXP® users, delivers highly accurate results
The superb accuracy defined in the TerraSAR-X data product specifications has now been confirmed by the Civil and Commercial Applications Project Group within the National Geospatial-Intelligence Agency (NGA). The group published the results of its geolocation accuracy evaluation of TerraSAR-X radar satellite imagery during the ASPRS Annual Conference in March 2009. In their paper, “Geometric Precision in Space Radar Imaging: Results from TerraSAR-X,” Thomas P. Ager, NGA systems engineer for radar, and co-author Paul Bresnahan of Observera Inc. describe the evaluation processes and parameters applied to 13 high-resolution SpotLight and another 13 StripMap acquisitions. These were collected in single-polarization, or VV mode, generated as multi-look, ground-range detected products with spatially enhanced processing, and included the rapid orbit metadata. Ager confirms, “The results of this evaluation are consistent with the accuracy values listed in the product specification,” and adds, “It is plausible that the TerraSAR-X accuracy is even better.”… Read more >>
BAE Systems implemented the sensor model for this data source in both SOCET SET and SOCET GXP. All exploitation tools in SOCET SET and SOCET GXP can be applied to SAR data.
Infoterra GmbH holds the exclusive commercial exploitation rights for the German radar satellite TerraSAR-X, launched on June 15, 2007. It enables the company to provide weather-independent, high-resolution radar data and reliable data access services.
