Coordinates China ｜ "Thousands of Miles Passage" to achieve "Space Kiss"

Xiaoxin said

In the past ten years, a series of heavy weapons and super engineering created by central enterprises have engraved new coordinates of national development from different dimensions. On September 12th, the online theme promotion of "our ten years@coordinates China" was officially launched. Over the major achievements of representative infrastructure construction and scientific and technological innovation, it shows the courage, courage and wisdom of challenging the limits and challenging the limit.

On the journey of "Dream Flying", high -precision space meetings and docking technology is one of the most complicated technologies in the operation of spacecraft. China's self -developed microwave radar as a key measurement equipment for the long distance between the two spacecraft in the two spacecraft is called "Master" with a "thousand -mile needle". 0.1 degrees, which is equivalent to a precise "hollow" ball from Beijing's basket. Today, Xiaoxin brings you the tenth issue of the "coordinate China" series theme film, China's accurate "Space Kiss".

November 3, 2011

Tiangong -1 and Shenzhou 8 successfully implemented

China's first space meeting dock

It marks the third in the world in my country

Countries that independently master the connection and docking technology

December 6, 2020

380,000 kilometers away from Earth

Chang'e 5 successfully completed

The first monthly track in China has no one to meet with docking

Back the moon soil after the air relay

Construction at China Space Station

Freight spacecraft, manned spacecraft, experimental compartment and

Heaven and core cabin forward, backward, radial, etc.

Multiple meetings and docking

Continue to carry out, Lianshi victory

In the past ten years

The key core products of the meeting docking

25 microwave radar in China Aerospace Science and Technology Second Hospital

Accurate and reliable, unattended

Ensure strongly to complete the successful completion

On the journey of exploring the vast universe

Surprove a perfect answer sheet

Part1

How to achieve "thousands of miles"?

Two aerospaces

Flying in high -speed in space

High speed up to a few kilometers per second

"Find the other party" quickly

Relying on the radar "microwave" eye

Microwave radar is by radar host and responding machine

Two parts composition

Installed on two spacecraft

The two are like the ends of the phone

"Questions and Answers" through microwave implementation

Passing location and posture information

Continue "traction" spacecraft

Meet from each other

Until the completion

Part2

How accurate is radar "microwave"?

Microwave radar adopts 7 key core technologies

Within 100 kilometers

The ranging accuracy reaches 0.2 meters

The accuracy of the angle measurement reaches 0.1 degrees

Comprehensive measurement performance reaches international leading level

How accurate is it?

You can imagine

A slam dunk master stands in Beijing

Towards a basket in Tianjin, a hundred kilometers away

A "hollow" ball in accurate vote

This "master" is a microwave radar

Part3

How to continuously output accurate measurement information?

China Aerospace Science and Technology Second House

Microwave radar team since 1999

Start microwave radar independent development

From scratch, technical tackling

Through 20 years of innovation

Settle key technologies

In 2011 in Tiangong -1 and Shenzhou 8

In the first meeting docking task

Complete "First Show"

Chinese space meeting docking microwave radar technology

Among the world's first -class

Facing a more complicated moon environment

Microwave radar research team

Conquest with large angle range and high -precision measurement

Optimized design in the anti -moon dust and electromagnetic interference

"Fire Eye Golden Eyes" again

Realize Chang'e 5 "Moon Palace Hand in Hand"

After three generations of upgrade

Microwave radar is in normalization and series

In the direction of "horizontal and vertical two -dimensional" development

Smaller, lighter weight, and more fully functional

But the accuracy continues to improve

Continue to continue exporting for my country's space task

More accurate and reliable measurement information

Create Chinese accuracy with the ingenuity of central enterprises

China Aerospace Science

Deep mark on innovation, pioneering, and struggle under engraving

For the new era space career

Write a gorgeous movement

Continue to write "Hands to pick stars" space legends
