ERS-1 and ERS-2 parallel acquisitions

05 March 1997

Next week, during a 3 days ERS-1 instrument check-out, some areas in the visibility of Canadian and ESA stations and ground stations in Cordoba, O'Higgins, and Taiwan will be covered by ERS-1 and ERS-2 SAR in parallel.

Frames shifted in May 1996 ERS-1 SAR data

06 February 1997

The data acquired in May 1996 by the ERS-1 sensor presents an anomaly: the image data is shifted by about 6.5 Km in azimuth compared with the nominal expected frame (while the latitude/longitude annotated in the product corresponds to the nominal expected frame). The anomaly can be partially compensated by the ESA/ESRIN ERS service. If necessary and behind specific request re-processing of data could be comtemplated. In turn new orders will be processed directly with a compensation method. Please note that only RAW, PRI, SLC and SLC-I products can be accepted for that timespan. For information the orbits concerned are 25203 to 25479. For ascending satellite passes the shift takes place northwards while for descending passes it occurs southwards. For more details do not hesistate to contact EOHELP.

Applications of ERS data by subject

01 February 1997

Why can ERS SAR provide information on tropical agriculture and deforestation even when the skies are very often cloudy? How is ERS data used in the management of the Coastal Zone? How can high precision ERS SAR assist in the task of compiling and updating maps? In what ways do ERS data contribute to forecasting of marine risks such as high winds and waves, and nowca sting of sea ice? How can ERS help to assess risks and aid response to natural disasters?
