    Sentinel-1A is a European radar imaging satellite launched in It is the first Sentinel-1 satellite launched as part of the European Union's Copernicus. Sentinel-1 is the first of the Copernicus Programme satellite constellation conducted by the European Space Agency. This mission is composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B, which share the same orbital plane.

    They carry a C-band synthetic-aperture radar instrument which provides a. The Sentinel-1 mission comprises a constellation of two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging.
    A direct LEO-to-Ground downlink is also possible and could reach data rates of up to 5.

    The RWA consists of four wheels to achieve three-axis control with built-in redundancy. The map may be less reliable over vegetated areas but can provide useful guidance in identifying damaged areas. Three priorities fast-track services for the mission have been identified by user consultation working groups of the European Union: Marine Core Services, Land Monitoring and Emergency Services.

    The large chasm running northwards is called Chasm 1, while the split extending eastwards is referred to as the Halloween Crack.

    Early maps from the s indicate that the ice shelf used to be a mass of small icebergs welded together by sea ice. The FSS is 16 by At nearly km long, the Lena River is one of the longest rivers in the world.

    Sentinel-1 is the first of the Copernicus Programme satellite constellation conducted by the European Space Agency.

    Sentinel-1 is a two satellite constellation with the prime objectives of Land and Ocean monitoring.

    Each image pixel is represented by I and Q magnitude values. Data products can be used for SAR Interferometry applications. WV mode resembles ERS and Evnisat mode, but with better spatial resolution, larger vignettes and a 'leap frog' acquisition pattern.

    C-SAR is an active phased array antenna created to provide a faster scanning in different elevations and in azimuth.
