Shenzhou-13's return capsule touched down at the Dongfeng landing site in North China's Inner Mongolia autonomous region at 9:56 a.m. on April 16. In the meantime, the rescue helicopter also landed at the same site.

Unlike airport, the Dongfeng landing site is a large and geographically complex area without paved runways. Affected by wind, it is nearly impossible to make accurate prediction on the return capsule's landing point. Moreover, its small size made itself hard to be found right after landing.

According to the 22nd Institute of China Electronics Technology Group Corporation located in Xinxiang city of Central China's Henan province, its newly-developed series of orientation devices are indispensable to the accomplishment of this task.

The new series of devices can capture the first signal sent by the return capsule after passing through the "black barrier", thus quickly determining the capsule's real-time position.

As the guarantee of timely finding of the return capsule, the series of orientation devices, dubbed as the "eyes" of the recovery and rescue team, made breakthroughs in a number of key technologies. Its strong adaptability to different environments will help ensure that the positioning signal transmitted by the return capsule can be tracked at anytime and anywhere.
