EO Data: Sentinel-1

EO Data: Sentinel-1

SENTINEL-1 is the main source of EO data for GEORICE project. It is the first of five missions that ESA is developing for the Copernicus initiative of the European Commission (EC) and the European Space Agency (ESA).

The SENTINEL-1 mission is designed to provide enhanced revisit frequency, coverage, timeliness and reliability for operational services and applications requiring long time series as for rice monitoring. The mission provide an operational interferometry capability through stringent requirements placed on attitude accuracy, attitude and orbit knowledge, and data-take timing accuracy.

The mission is composed of a constellation of two satellites, SENTINEL-1A and SENTINEL-1B, sharing the same orbital plane. This constellation cover the entire world’s land masses on a bi-weekly basis, sea-ice zones, Europe’s coastal zones and shipping routes on a daily basis and open ocean continuously by wave imagettes.

The SENTINEL-1 mission includes C-band imaging operating in four exclusive imaging modes with different resolution (down to 5 m) and coverage (up to 400 km). It provides dual polarisation capability, very short revisit times and rapid product delivery. For each observation, precise measurements of spacecraft position and attitude are available.

A Synthetic Aperture Radar (SAR) has the advantage of operating at wavelengths not impeded by cloud cover or a lack of illumination and can acquire data over a site during day or night time under all weather conditions.
