"Xihe" brings us into the era of "exploring Japan" state-owned instrument enterprises are valued

[ Focus on Chemical Machinery Equipment Network ] The enterprise is the main body of innovation, and the central enterprise is the national team for scientific and technological innovation
.
State-owned enterprises, especially state-owned enterprises under the central government, must strengthen their independent innovation capabilities, research and develop and master more important national weapons
.
During the "14th Five-Year Plan" period, central SOEs will further increase R&D investment and speed up the capture of a number of key core technologies that are "stuck-necked"

"Xihe" Exploring the Sun
 
On October 14, the Long March 2D rocket carrying China's first solar exploration science and technology test satellite "Xihe" was successfully launched at the Taiyuan Satellite Launch Center, and China officially entered the "sun exploration" era
.

 
The main satellite launched this time is the solar Hα spectrum detection and dual super platform science and technology test satellite, which was developed by the Eighth Academy of Aerospace Science and Technology, and applied maglev technology in orbit, aiming to complete the ultra-high pointing accuracy platform and the stability platform in-orbit flight test
.
The scientific payloads, such as the solar space telescope, will carry out international solar Hα-band spectral imaging detection, and promote the collaborative innovation and development of China's space technology and space science
.

 
This mission also carried and launched 10 small satellites, such as the orbiting atmospheric density detection satellite and the commercial weather detection satellite
.
The Long March 2D carrier rocket is a liquid two-stage carrier rocket at room temperature with single-satellite and multi-satellite launch capabilities with different orbital requirements
.
This time, the Long Erding rocket adopts a carrying disk configuration, breaking through the previous side wall carrying, and the number of satellites and envelopes are limited, and the number of satellites carrying is expanded to 10
.

 
The Changer Ding rocket applied the grid rudder landing zone control system to carry out performance verification tests
.
Through the unfolded grid rudder, the attitude control of the return of the first sub-stage can achieve the goal of reducing the range of the first sub-stage landing area by more than 80%, making the landing point of the launch vehicle more precise and controllable, and greatly improving the safety environment of the landing area
.

 
Wireless energy and 1200W wireless charging, high-speed laser communication
 
This satellite is developed by the 811 Institute of the Eighth Academy of China Aerospace Science and Technology Corporation, which undertakes the entire satellite energy collection, storage, and distribution tasks
.

 
This is the domestic scientific test satellite project to realize the application of high-power, high-reliability and high-efficiency wireless energy transmission technology.
It has a high power of 1200W and a voltage range of 50V-100V
.
The satellite realizes an intelligent and integrated design system scheme for energy collection, energy storage, energy control management and secondary power distribution
.

 
In space, both solar panels and batteries provide direct current.
In the process of wireless energy transmission between the load bay and the platform bay, it needs to go through a conversion process from DC to AC to magnetic field, and then from magnetic field to AC to DC.

.
From energy input to output, the overall conversion efficiency of the entire link reaches more than 80%; in the magnetic field coupling part, the magnetic transmission efficiency reaches more than 95%, realizing high-efficiency and low-heat energy transmission
.

 
In addition, the satellite adopts two "mutual backup" wireless communication methods, laser communication and microwave communication, and sets up a 5G high-speed communication channel between the two cabins, further improving the efficiency and reliability of inter-cabin communication
.

 
There is also a "new face" on the "Xihe"-a stand-alone high-speed laser communication in the cabin
.
The equipment was developed by the 802 laser center team of the Eighth Academy of Sciences and is responsible for cabin data transmission.
This is also a cabin cableless laser data transmission device connected to the satellite platform.
It will work in orbit for three years as planned
.

 
　　"Xihe" will perform high-resolution spectral imaging of the sun, which will generate huge scientific data
.

 
　　The laser communication subsystem has a high-speed laser transmission interface, which can increase the data transmission rate of scientific payloads, greatly increase the data transmission bandwidth within the satellite, and provide an effective guarantee for the accumulation of high-definition imaging data of the payload
.
In addition, the integrated electronic sub-system platform bay management unit and 14 load bay products of the Eighth Institute of Electronics are responsible for providing the entire satellite with functions such as ground measurement and control, data transmission, and satellite management, which are also indispensable on the "Xihe".
The "black technology"
.

 
　　It is reported that the first-hand flight test data obtained by the "Xihe" on-orbit flight will greatly reduce the risk of subsequent application of the dual-supermarket control technology, laying a solid technical foundation for the serialized development of the dual-supermarket platform
.

 
　　In the future, the dual-super platform technology will also be widely promoted and applied in new-generation space missions such as high-resolution detailed ground surveys, large-scale three-dimensional surveying and mapping, three-dimensional solar exploration, and exoplanet discovery, greatly accelerating China’s progress in becoming a space power.
, To promote the leapfrog development of China's space science and aerospace technology fields
