Minimize Mission Objectives

The mission provides an independent operational capability for continuous radar mapping of the Earth.

The SENTINEL-1 mission is designed to provide enhanced revisit frequency, coverage, timeliness and reliability for operational services and applications requiring long time series.

The mission will provide an operational interferometry capability through stringent requirements placed on attitude accuracy, attitude and orbit knowledge, and data-take timing accuracy.

The constellation will 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 SAR instrument and short revisit time will greatly advance users’ capabilities and provide data routinely and systematically for maritime and land monitoring, emergency response, climate change and security.

Each SENTINEL-1 satellite is expected to transmit Earth observation data for at least 7 years and have fuel on-board for 12 years.

The SENTINEL-1 Mission Requirements Document (MRD) describe all mission specific requirements in detail.
