With the launch of the Shenzhou 16 spacecraft, the "Shenzhou" spacecraft from the 510 Institute of the Fifth Academy of China Aerospace Science and Technology Corporation (hereinafter referred to as the "Aerospace 510 Institute") has entered the public eye. The Aerospace 510 Institute was established in 1962 and is the earliest professional research institute in China engaged in vacuum science and technology. The products developed are widely used in various satellite and ship missions launched, making outstanding contributions to major special engineering tasks such as manned spaceflight, lunar exploration engineering, and Beidou navigation. The "Space Siri" is one of the 43 products (sets) undertaken by the institute for this mission. During the operation of the spacecraft, it provides astronauts with reminders of important events and flight plans, as well as voice broadcasts of various alarm messages, "said Zeng Zhengyi, a senior engineer at the institute. The "Shenzhou Intelligent Flashlight" mainly provides lighting for astronauts' work and life inside the cabin, as well as camera assisted lighting for the rendezvous and docking between manned spacecraft and space stations in shaded areas. Yang Jun, the R&D leader of interior/exterior lighting equipment, introduced that the interior lighting equipment (close range floodlighting) and rendezvous and docking lighting equipment (long-distance transparent lighting) of the Shenzhou 16 spacecraft use advanced solid-state lighting sources, which have the advantages of shock resistance, vibration resistance, low power consumption, and high stability. How can search and rescue personnel accurately locate the return capsule? The 'spacecraft GPS' is particularly important, as it relates to the success or failure of the entire mission and the safety of astronauts' lives. According to Wang Kai, a senior engineer at the institute, "spacecraft GPS" refers to an international rescue position indicator, which integrates positioning information acquisition, data processing, coding, modulation and transmission. It has high positioning accuracy and can achieve reliability and effectiveness in emergency rescue, This beacon signal meets international standards and can be recognized by the global maritime satellite search and rescue system with shore stations all over the world, ensuring that search and rescue personnel can quickly find the return module
