CCAP: TerraSAR-X Accuracy Exceeds Standards

[Satellite Today 03-19-09] The Civil and Commercial Applications Project (CCAP) group within the U.S. National Geospatial-Intelligence Agency (NGA) asid the geolocation accuracy and performance of Infoterra’s TerraSAR-X data product exceeds the product description’s own standards, according to a report released March 17.
    Thomas Ager, author of the report titled “Geometric Precision in Space Radar Imaging: Results from TerraSAR-X,” said the results of an evaluation process of high-resolution SpotLight and StripMap acquisitions “are consistent with the accuracy values listed in the product specification. … It is plausible that the TerraSAR-X accuracy is even better.”
NGA’s CCAP performs geolocation accuracy evaluations for civil and commercial imagery being purchased or considered for purchase by the agency.
