Sentinel 1
Encyclopedia
Sentinel 1 is a future space mission from ESA
of GMES
program.
The payload of Sentinel 1 is a Synthetic Aperture Radar
in C-band which provides continuous imagery (day,night and all weather).
On 12th March 2010, the European Space Agency and Thales Alenia Space signed a contract worth €270 million to build the Sentinel-1 satellite.
A launch date around 2013 is foreseen.

Synthetic aperture radar
Synthetic-aperture radar is a form of radar whose defining characteristic is its use of relative motion between an antenna and its target region to provide distinctive long-term coherent-signal variations that are exploited to obtain finer spatial resolution than is possible with conventional...

It will provide continuity of data from ERS and Envisat missions, with further enhancements in terms of revisit, coverage, timeliness and reliability of service.A summary of applications are:
- Monitoring sea ice zones and the Arctic environment, and surveillance of marine environment.
- Monitoring land surface motion risks
- Mapping of land surfaces: forest, water and soil
- Mapping in support of humanitarian aid in crisis situations
