|TerraSAR-X and TanDEM-X dependably acquire high-resolution and wide-area radar images independent of the weather conditions. The two satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor. With the upcoming addition of PAZ, the three almost identical satellites will be operated in a constellation and will deliver optimized revisit time, increased coverage and improved service.||
It plans to launch in orbit on 3Q 2015 the third twin to TerraSAR_X / TanDEM-X satellite name PAZ. After starting the operating, frequency revisits will increase from 43 hours to 21 hours.
