双语说河南｜神舟十三号定位系统是咱河南制造

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.

4月16日9时56分，神舟十三号载人飞船返回舱在东风着陆场成功着陆。就在返回舱着陆的同时，前来接应的搜救预备分队空中分队直升机也降落到了现场。

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.

要知道，东风着陆场并非一个方圆几平方公里的“飞机场”，而是地形复杂、地广人稀的大范围区域；受风速、风向等各种因素影响，返回舱的着陆点无法固定——再加上返回舱体积较小，想要迅速锁定返回舱位置实现“舱落人到”，难度堪比“海底寻针”。

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.

4月17日，记者从位于新乡的中国电子科技集团公司第二十二研究所（以下简称“22所”）获悉，能顺利完成这一高难度任务，为迎接航天员出舱争得最宝贵时间，该所提供的新型定向仪系列产品功不可没。

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.

据新型定向仪设计人员介绍，22所研发的系列产品，能第一时间捕捉返回舱冲出“黑障”后发出的首个信号，快速确定返回舱的即时位置。

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.

据了解，作为着陆场发现返回舱的保底手段，该产品突破了测向抗干扰、虚拟极化合成等多项关键技术，在环境、平台等方面适应性强，无论天空海上、风霜雨雪、寒暑昼夜，都能第一时间确定着陆返回舱发射的标位信号，引导搜救力量快速抵达落点，被誉为返回舱回收的“火眼金睛”。
