Ludi Tance 1-01A (L-SAR 01A), lead satellite of a Chinese radar interferometry pair testing the same trick Germany's TanDEM-X pioneered — two satellites flying in precise formation, comparing radar echoes of the same ground to build 3D elevation models accurate to a few meters, entirely independent of weather or daylight.
