A variety of equipment in the space station can be used as a network terminal According to experts, more than 10 wired and wireless network cameras, wired and Bluetooth headsets, mobile phones, PADs, and laptops can all be used as network terminals on the space station’s Tianhe core cabin. These terminals connect the collected image and voice data to the in-cabin Ethernet switch through wired or wireless Wi-Fi, and transmit it to the ground via a relay link through a high-speed communication processor. On the morning of June 23, the space station call was held at the Beijing Aerospace Flight Control Center. Just like on the ground, phone calls and text messages must be made through the antenna of a mobile phone. The communication between the space station and the ground is mostly done by the relay antenna on the core module. At an altitude of 40,000 kilometers, the space-based measurement and control network composed of Tianlian-1, 03, 04, and Tianlian-2 01 is like a “space base station”, connecting the core module and the ground station to create a space “sky Road”. Voice, video, e-mail data and downlink scientific experiment data between the space station and the ground all go through this “road to heaven”. Like at home, you can talk to whoever you want to talk to In terms of experience, the voice processor of the space station can not only make the astronauts in the space station feel like they are at home, make calls inside and outside the station, but also connect with the Shenzhou spacecraft on the way, and even establish a connection.

Space station voice processor developed by the Eighth Academy During group chat, you can also adjust the volume separately for each end, which is more precise and practical to use. Astronauts can access chat in any corner of the space home, and accurately set single or multiple call partners. In the space network speed, the downlink rate of the communication link is 1.2Gbps, which is equivalent to the terrestrial 5G communication rate. The relay satellite ground station receives space data in real time, then transmits the data to the Beijing Flight Control Center, and then automatically distributes it according to different identifiers, with a delay of only seconds. 360-degree panoramic camera for real-time high-definition imaging Experts from the Eighth Academy said that this new generation of image products adopts high-definition digital imaging technology and the latest international image compression coding method to increase the image resolution from the original standard definition to 1080P high definition. While the image definition is greatly improved, The code stream is also controlled within the tolerable range of the system. At the same time, the high-definition camera architecture adopts a fully digital and integrated design, which not only includes all the functions of the second-generation camera and image encoder, but also includes image acquisition, preprocessing, encoding, network transmission and other functions, so that the product can meet different requirements. Channel conditions and user needs. “In order to cope with the harsh environment such as the huge temperature difference outside the cabin, space radiation, atomic oxygen erosion, etc., we also put a layer of’protective film’ with a temperature control function on the outside camera to ensure the stability, reliability and reliability of the outside camera. Image quality.” said Shen Jianfeng, the chief designer of the extravehicular high-definition camera. In order to meet the 360-degree panoramic surveillance of the extravehicular and when the astronauts exit the capsule during the flight, the 4 panoramic cameras currently installed in the space station’s sky and core capsules have a 360-degree panoramic field of view real-time imaging function, which is the first in the domestic aerospace field. It realizes real-time splicing and fusion of multi-channel images, and has video output and photo output functions at the same time, meeting the requirements of high-definition video output with a horizontal 180-degree field of view and panoramic photo output with a horizontal 360-degree field of view and a vertical 100-degree field of view. “With these high-definition and panoramic cameras, the rendezvous and docking during the construction of the space station, the deployment of solar wing windsurfing boards, the lifting of relay antennas, the monitoring of the status of the astronauts in the cabin, and the astronauts’ world-to-earth calls can be recorded by our cameras Wonderful moment.” said Xu Qi, the chief designer of the panoramic camera of the Eighth Institute of Electronics
