The ESA ground stations directly acquire
SAR data over the European area. International
Ground Stations (IGS) also receive ERS
data. Full-resolution SAR data cover
almost all of the land surface, and much
of the oceans. Low Bit Rate (LBR) data
from the other instruments are stored
on board the satellite for transmission
to ground stations, providing complete
worldwide coverage.
The ESA acquisition strategy to-date is
to acquire, where possible, data of all
land areas using SAR Image Mode, within
the constraints of power limitations. To
be certain of any future acquisition, programming
requests should be placed in advance. The
AMI is routinely switched to Wind/Wave
Mode over oceanic areas. Orders for SAR
Image data of oceanic areas (e.g. for ship
and oil monitoring) should be made in advance. |
