THE TERRASAR-X/PAZ RADAR

SATELLITE CONSTELLATION

In 2012, Hisdesat entered into an agree-
ment with Airbus Defence and Space
(formerly Astrium GEO) for the creation
of a constellation of radar satellites, by
coordinating the resources that PAZ,
TerraSAR-X and TanDEM-X make availa-
ble to clients. Some of the advantages of
this constellation are:

— Significantly reduced revisit time
(between 4 and 7 days), important
for interferometric processes and
applications with strict time requi-
rements

— Improved capacity for surveillance
applications and map generation

— A simplified client request process
via a single portal and a single ser-
vice catalogue
