At 23:08 on November 29, the Shenzhou 15 manned spacecraft was successfully launched. The "Classic Eye" developed by Xinxiang City for the 15th time staring at return capsule , protecting the launch of three astronauts. In order to be foolproof, China Electronics Technology Group Corporation has formed an on-site support team of 15 people to implement technical support at the mission site, providing "nanny-style" thoughtful guarantee for the launch of Shenzhou 15 without blind spots.

"Classic Eye" is called a positioner, developed by the 22nd Research Institute (22nd Institute) of China Electronics Technology Corporation located in Xinxiang City. Its function is that whether astronauts are returning in the return capsule (launched ascendant phase) in an emergency moment or completing the mission, they must promptly, accurately and quickly discover the location of the return capsule in a timely, accurately and quickly, and guide the search and rescue forces to quickly arrive at the return capsule landing point to rescue astronauts, which is an important guarantee for ensuring the safety of astronauts.
Directional instrument is like Sun Wukong's fiery eyes, like a pair of "wisdom eyes" accurately positioned in the vast dark night. It is equipped on a diverse search platform such as transporter , helicopters, search vehicles, and rescue ships. It can receive the "call" signal from the return capsule. Through this signal, you can know the exact location of the return capsule, and you will discover the return capsule as soon as possible, guiding the search and rescue forces to quickly arrive at the return capsule landing point to rescue astronauts, and even know the status of the astronauts in the return capsule in advance.

According to the relevant person in charge of the Institute of 22, since the directional instrument adopts a radio "call-reply" working mode, it is different from other search methods such as radar , optics, etc., and will be greatly affected by external environmental factors. The directional instrument can position the return capsule all day, all day, and no blind spots, especially in night and harsh climate conditions, its advantages are more prominent. Whether in the Gobi desert or in the distant ocean, whether it is day and night, wind and rain, it can find the return capsule.
It is understood that the helicopter front cabin search and guidance system developed by Institute 22 will also be applied to air search and rescue. Thanks to the adoption of advanced technologies such as machine learning and multi-source information fusion, it constantly collects information seen by the "eye" such as radar, optics, navigation, telemetry, and communication and processes it, and then pushes it to the front cabin pilot in the most concise form to provide accurate guidance for the pilot. At the same time, it is accurately synchronized with the landing forecast data of the Beijing accusation hall. Searching for helicopters can predict the operation trajectory of the return capsule in advance, and gains valuable "advance" for finding the return capsule.

This year marks the 30th anniversary of the approval and implementation of the manned spacecraft project. Over the past 30 years, the 22 manned space mission teams have always adhered to the original aspiration and mission of "providing scientific and technological support for spacecraft landing and recycling". Generations of people have continued to strive to create many firsts in the history of my country's spacecraft landing and recycling: the first "vehicle-mounted directional instrument", the first "ship-mounted directional instrument", and the first "air-mounted directional instrument", ensuring the successful completion of the mission of finding the launch and recovery return capsules of previous manned space projects.
