Sentinel-1 satellites combine radar vision
22 June 2016
The twin Sentinel-1 satellites have – for the first time – combined to show their capability for revealing even small deformations in Earth's surface.
Following its orbital manoeuvres, the recently launched Sentinel-1B satellite reached its designated orbit position on 15 June.
The satellite is now orbiting Earth 180° apart from its twin, Sentinel-1A, at an altitude of almost 700 km. With both satellites finally in the same orbit, together they can cover the whole globe every six days.
The two-satellite ‘radar vision' mission for Europe's Copernicus programme carries an advanced radar to provide an all-weather, day-and-night supply of imagery of Earth's surface.
