TerraSAR-X and TanDEM-X flying in close formation

TerraSAR-X and TanDEM-X flying in close formation
On 14 October 2010, the radar satellite TanDEM-X transitioned to close formation flight with its ‘twin’ TerraSAR-X. This image shows the two satellites flying together – ‘side-by-side’ – 350 metres apart. The two satellites operate in synchronisation and are able to perform simultaneous data acquisitions of the same area.
