What difficulties did BDS 3 encounter at the beginning of its development?

I think there are four main difficulties in the early stage of the development of Beidou-3:

1.There is a lack of talent in related aspects.

2.There is a lack of research data and related equipment.

3.The State has not allocated sufficient funds.

4.Blockades and obstructions in Europe and the United States.

In the early stage of construction, there were relatively few talents, and the state carried out long-term personnel training. At the same time, there is a lack of information and equipment. It is also limited by the technological level of European and American countries.

At the beginning of the development of Beidou-3, the most difficult thing was the problem of science and technology, which could not further reduce the error range, and the accuracy error of the satellite was somewhat large, but in the end, it relied on the efforts of scientists to solve this problem!

At the beginning of the development of Beidou-3, it encountered the difficulty of lack of talents, and it was necessary to cultivate talents. And there is a lack of a lot of information, as well as related equipment. When I first started researching, I was blocked and hindered by European and American countries.

The first is the lack of talents in the initial research of the Beidou navigation system, and the need to cultivate talents. The second is the research and development stage of the Beidou navigation system, which lacks a large amount of information and related equipment, and the third is that the Beidou navigation system has just begun to be researched, which is blocked and hindered by European and American countries. Fortunately, our country overcame many difficulties and finally completed the research and development of Beidou-3.

What difficulties did BDS-3 encounter at the beginning of its development? The Beidou navigation system is very good, the accuracy can be said to be very high, it was officially started on July 31, which has direct benefits for China's science and technology and economic development, of course, at the beginning of the development of the Beidou navigation system, we encountered a lot of difficulties, the following will give you a specific introduction, friends for reference:

1. There is a lack of talents in the initial research of Beidou navigation system, and it is necessary to cultivate talents

Beidou navigation system is of great significance to our country, you must know that the United States GPS system, although it seems that it is open to the world, but the United States can be closed to others at any time, that is to say, an excuse will make a country completely lose the GPS function, which has a huge obstacle to national defense security and related economic development, China has also suffered in GPS, so the country is determined to develop its own. Due to the development of the Beidou navigation system, China lacks some professional personnel, the country can only find ways to train specialized personnel from various colleges and universities, which is a relatively arduous process, but also the biggest difficulty, but China's scientific research personnel persevere, and finally become full of talents.

Beidou navigation system for scientists, the most difficult point is the lack of relevant information, as well as related precision equipment, these need to be studied by China itself, because Beidou navigation system is a new technology, we need to go our own way, to avoid being controlled by others, so data and equipment is the most difficult thing, but Chinese scientists, or successful.

3. The Beidou navigation system has just begun to be studied, but it has been blocked and hindered by European and American countries

In the research stage of the Beidou navigation system, European and American countries have been hindering China's development at the technical level, and even blocking some relevant news and technology, these difficulties have not hindered the development of China's Beidou navigation system, Chinese researchers are very tenacious, and we have succeeded with our own high-end technology.

The main thing is that the export restrictions of major scientific and technological countries on China's main components, as well as the fierce competition in the market, the satellite systems of the United States, Russia, and Europe were very perfect at that time, and we were just starting out, and the key is the scarcity of talents.

The technical problem is a difficult problem to overcome, and the second is that the accuracy is also difficult, but fortunately, it is the persistence of the researchers that it can be achieved.

In the early stage of the development of Beidou-3, the country's limited research and development funds and the lack of complete mastery of high-precision aerospace technology were the primary problems encountered in research. The development of the aerospace industry will inevitably overcome many difficulties, and China's astronauts have been working hard to tackle key problems under the existing conditions, and finally achieved breakthroughs.

The main thing is the monopoly of the great powers on navigation. At first, the United States, Europe and Russia were able to use their navigation systems on a large scale because of their strong scientific and technological capabilities, and China's Beidou navigation not only faced a fierce competitive environment, but also was monopolized by major powers in terms of key technologies, so they could only find their own way out. The monopoly problem is the biggest obstacle to the development of the Beidou system.

The significance of BDS-3 to the country and individuals is as follows:

1. The impact of Beidou satellite navigation on China's industry.

According to the "Medium and Long-term Development Plan for the National Satellite Navigation Industry", the scale of China's satellite navigation industry will reach 400 billion yuan in 2020, of which the contribution rate of Beidou satellite navigation system and its compatible products will reach 60%, and the important application fields will reach more than 80%.

Navigation systems have significant applications in many fields, such as the current development of autonomous driving, where enhanced positioning functions are an indispensable part. There are other shared transportation, smart phones, drones, Internet of Things, wearable devices and other terminals will have rapid development with the support of navigation systems, which are all indispensable industries for future economic development.

2. The impact of Beidou satellite navigation on personal life.

Beidou satellite navigation has many impacts on our personal lives. For example, at the end of last month, 12 elderly people and 3 children in Kunming drove to the Nujiang River in Yunnan Province. As a result, the landslide caused the signal facilities to be damaged, and the family members could not get through, so they lost contact, and then they could be located and searched through satellite navigation.

Another example is the use of Beidou positioning technology, when buying vegetables in the market in the future, you can scan it with your mobile phone to track the growth location of vegetables and what fertilizers have been applied in the management process.

It can improve our country's comprehensive strength, and at the same time, let other countries dare not bully us and see our strength; For individuals, it is certainly a reminder of their own satisfaction, pride in the country.

Beidou satellites are related to China's national defense, economy, civilian and other aspects. For individuals, the Beidou satellite facilitates people's travel, and for the country, it is like a golden key to open the country, of course, it cannot stand in the hands of others, so I must develop it myself.

It can reflect the enhancement of China's comprehensive national strength, increase the sense of personal mission and responsibility of the people, and at the same time enhance the pride of the people and make the country strong, then everyone's living standards can be guaranteed.

The development of Beidou satellites can greatly improve the country's military strength, and at the same time, everyone can enjoy better positioning services.

The Beidou system can be called one of the greatest achievements in the development of China's aerospace industry in the past 20 years. In the scenarios where we use Beidou in daily life, most of them are used in positioning systems, and with the successful launch of the last satellite of the Beidou-3 system, the positive impact in real life will be visible to the naked eye.

It is slowly affecting living habits, and the shared bicycles that are commonly used when traveling, the smart locks of these bicycles have the positioning chip of the Beidou system to send, and the positioning information of the bicycles can also be monitored by the background of each vehicle, as well as sending scheduling instructions to nearby vehicles.

Applied to mechanical agriculture to improve productivity: When the Beidou system is applied to agriculture, it will bring great convenience to farmers' work. For example, Gansu has begun to focus on using modern technology to transform traditional agriculture.

The local area has begun to promote the use of satellite navigation, etc., high-precision technology in agriculture began to promote the development, in the local related enterprises have installed the Beidou system, mainly used for sowing potatoes, corn mulching and other field operations that consume more manpower, with the promotion of Beidou system agricultural machinery, to a certain extent, reduce the labor intensity of farmers.

After all, such a design requires a lot of difficulties, and at the same time, it is also necessary to understand the sky and some environments in the satellite, so that the measurement can be more reasonable to set the key grinding hail meter, and can also design more good things.

After experiencing some difficulties and obstacles, I also experienced a shortage of funds, and at the same time, when facing some environmental factors and equipment shortages, I also paid a lot of heart-to-heart blood. Only then was the global satellite navigation system completed.

It is not easy for these engineers, many of them are constantly transporting in bulk without research, and these technologies are controlled by developed countries at that time, and we have no way to obtain relevant knowledge, only to verify step by step.

1. Beidou-3 was successfully launched at Xichang Satellite Center. The Beidou-3 satellite navigation system consists of 24 medium-circle earth orbit satellites, 3 geostationary orbit satellites and 3 inclined geosynchronous orbit satellites, a total of 30 satellites.

2. The BDS-3 satellite navigation system provides two service modes, namely open service and authorized service. The open service is to provide positioning, circular speed measurement and timing services free of charge in the service area, with a positioning accuracy of 10 meters, a timing accuracy of 50 nanoseconds, and a speed measurement accuracy of meters and seconds. The authorization service is to provide more secure tracking cavity world, speed measurement, timing and communication services and system integrity information to authorized users.

At 2:07 a.m. on November 19, China successfully launched the first Long March-3B carrier rocket at the Xichang Satellite Launch Center in the form of "one rocket and two satellites".

Four. Ten. 2. Forty-three Beidou navigation satellites. On December 27, the construction of the Beidou-3 basic system was completed and global services began.

On June 23, the last global networking satellite of Beidou-3 was ignited at the Xichang Satellite Launch Center.

The completion and opening of the Beidou-3 global navigation satellite system fully reflects the political advantages of China's socialist system in concentrating on major affairs, and is conducive to enhancing China's comprehensive national strength and promoting China's economic development and improvement of people's livelihood under the normalization of epidemic prevention and control.

It is of great significance to promote China's opening up to the outside world under the current international economic situation, to further enhance national self-confidence, and to strive to achieve the "two centenary" goals.

Over the past 26 years, all the personnel involved in the development and construction of the Beidou system have risen to the challenge, dared to fight tough battles, continued to struggle, carried forward the spirit of "two bombs and one satellite", and cultivated the Beidou spirit in the new era, which should be inherited and carried forward. It is necessary to promote the application of the Beidou system, do a good job in ensuring the stable operation of the system and other follow-up work, and make new and greater contributions to promoting China's economic and social development and promoting the construction of a community with a shared future for mankind.

The completion and opening of the Beidou-3 Global Satellite Navigation System fully reflects the political advantages of China's socialist system in concentrating on doing great things, and is conducive to enhancing China's comprehensive national strength and promoting the improvement of China's economic development and people's livelihood under the normalization of epidemic prevention and control.
