There are three types of application satellites according to their uses: first, radio signal relay: "international communication satellites", domestic communication satellites, military communication satellites, maritime satellites, broadcasting satellites, tracking and data relay satellites, and search and rescue satellites. These satellites are equipped with transponders and antennas operating in various frequency bands, which relay radio signals from ground, sea, air and low-orbit satellites for the transmission of telephone, telegraph and television broadcasts, as well as data communications. Except for some satellites with large elliptical orbits, most of these satellites operate in geostationary orbits.

The second type of earth observation platform: this type of satellite includes meteorological satellites, earth resources satellites, and reconnaissance satellites, which are called earth observation satellites. These satellites are equipped with remote sensing instruments or other detection instruments of various wavelengths from ultraviolet to far-infrared light for earth observation, collect electromagnetic waves from various frequency bands of land, sea and atmosphere, extract useful information from them, and analyze, judge and identify the nature and state of the measured object. These satellites can directly serve meteorology, agriculture and forestry, geology, water conservancy, surveying and mapping, oceanography, environmental pollution, and military reconnaissance. Many of these satellites are in sun-synchronous orbits, while others use geostationary orbits and other orbits.

The third category is used for navigation and positioning datums: such satellites include navigation satellites, geodesic satellites, etc. These satellites are equipped with light beacon lights, laser reflectors and radio beacon machines, transponders, etc. The spatial position, distance to the ground and the speed at which such satellites operate can be predetermined, and can therefore be used as a reference for positioning, navigation and geodesy. Ground-based fixed or moving objects, airplanes and ships at sea can use these satellites to determine their own coordinates. The orbits of such satellites are mostly polar.

It can be said that the trajectories of different satellites are different, according to the convention, just the navigation system, there are more than 20 satellites!

The white technicians installed the systems almost mechanically.

Immediately afterwards, the staff of Yige Group began to accept.

The acceptance results are very satisfactory, and they are much stronger than some of the satellites that the United States is using.

Yige Group finally has its own super-tech satellite system, which includes satellite communication, reconnaissance, surveying and mapping, navigation and other functions.

"Mr. Bertram, your company's level of business is very high! All systems are working perfectly! ”

Long Wu was dressed in a Tang costume, and after the acceptance, he shook hands with the representative of Yelihua Company.

The foreigner named Bertram also had the same petrified expression as those technicians, and his mind was full of question marks, wasn't it a satellite model that the company sold to these Huaxia people?

What kind of monster is this sent into space?

Satellite broadband communication systems already exist in the United States and other Western countries, and many developed countries are eyeing the huge cake of China.

Because the development and application of broadband satellites in Huaxia lag behind that of developed countries, and Huaxia is vast, with a large population, and a very huge application market.

At this time, Bertram already knew in his heart that they must have invisibly offended many partners today, which is how many jobs of their peers have been smashed.

However, fortunately, the launched satellite was not studied by the official of Huaxia and was directly launched into space, and the technology was not leaked.

"This satellite navigation map is very useful! I hope it can be mapped and mapped soon! ”

Qin Xiaolu is full of confidence in the prospects of satellite navigation maps.

She is looking forward to the practical effects of satellite navigation maps. Because, before that, she used the funds on hand to acquire three courier companies.

This move puzzled many people, the three express companies she acquired were not big, and their reputation was very poor in the industry.

If you rate these three express companies, the highest speed index is only 3 stars, the lowest one has only one star, the staff quality is 1 star, the customer evaluation is 2 two stars, and the price is 3 stars.

No matter which way you look at it, these three express companies are the kind of people who can't do it and are about to go out of business.

When Lin Qingyi learned of Qin Xiaolu's thoughts, she couldn't help but be impressed by her.

In this world, the first element that limits the development of online shopping is that it cannot be tried like a physical store, and the return rate is high.

The second element is that the payment is in the hands of the bank.

The third element is express delivery!

Lin Qingyi also deeply felt this point, in the previous world, when the express delivery industry had not really developed, it took more than five days to send an express delivery, or even longer.

If there is such a long waiting time, customers who need goods urgently need to go directly to the physical store to buy them.

What restricts the speed of express delivery, in addition to transportation, is the delivery route!

Undoubtedly, Qin Xiaolu's own gaze was extremely accurate, not as Qin Guoqing thought, completely dominated by emotion, and realized the huge prospects of the satellite navigation system proposed by Lin Qingyi from the beginning.

"Don't worry, cousin! Now that the satellite is in the sky, it will soon be possible to map and map the satellite map, there are maps and navigation satellites, and the satellite navigation map will soon be perfected! ”

The principle of mobile phone navigation Lin Qingyi knows that it is by receiving the signals of at least 4 satellites, so as to realize the coordinates x, y, z and the clock difference Vto of the receiver, and finally realize the positioning and tracking function. So, theoretically, as long as the mobile phone can receive 4 satellites, no matter which system they come from, it will be able to complete the navigation mission.

At this time, Lin Qingyi finally took a solid step!

She took out her mobile phone and posted a Weibo: "We can use our mobile phones to watch the live broadcast of space tonight!" ”

"Brother Yi, what is space live broadcasting? You're not already in the sky, are you? ”

"Phew! Upstairs, you're in the sky! ”

"The missing person returns, first brother, you won't be stupid for building a school recently, right?"

"Brother Yi didn't want to talk and threw a school at you!"

In the past month, Lin Qingyi has indeed disappeared from the Internet for a month, but legends about her have been circulating in the rivers and lakes.

According to incomplete statistics, there are more than 80 'Linhai Hope Primary Schools' that have been built or are under construction, covering dozens of districts and counties.

Therefore, although Lin Qingyi did not make any remarks in front of the public this month, her loyal fans spontaneously defended her.

Whenever someone is on the Internet Black Forest Light Clothes, there are fans on the side who kindly persuade that a brother can't be black, this is true!

This Weibo not only caused a huge wave among fans, but also dropped a depth charge on the Internet.

Does anyone in Huaxia launch a private satellite? No!

"Lin Qingyi really launched a private satellite?"

At the same time, some financiers who had previously analyzed Lin Qingyi on the Internet were also surprised.

"Lao Mei didn't cheat her?"

In fact, most of them, like Qin Guoqing, can only do OEM and import talents.

To put it simply, the most tiring and dirtiest work is done by Chinese people, but the link of making money is in the hands of foreigners.

Chen An's posture of watching the play appeared: "Didn't you say that you want to broadcast live at night?" Shall we see later? ”

Wang Hongfa also said: "I hope it won't be a joke then!" ”

Except for Qin Guoqing, no one knew that Lin Qingyi's satellite had actually been successfully launched at this time.

The reason why Lin Qingyi posted this Weibo is to build momentum for the upcoming Huanyutai.

Satellite stations are not the same as satellite TV stations, and without the backing of the state, income can only be generated by advertising.

At the same time, there is no need to use terrestrial satellite receivers to receive signals in the closed-circuit system promoted by the broadcasting bureau.

This kind of terrestrial satellite receiver looks like a pot lid, and most of them are popular in remote mountainous areas where CCTV does not cover them.

However, the signal emitted by Lin Qingyi's super satellite is actually different from the traditional satellite signal, and the signal can be searched through the mobile phone.

At this moment, a system prompt sounded: "Congratulations to the host!" Complete the main quest 3 and get a mystery reward! ”

"Mystery reward?"

Lin Qingyi has seen this reward more than once, and this also depends on luck, or being able to open a new function of the system, or being able to strengthen an organ in the body, or being able to obtain a high-level skill.

At any time, with anticipation, Lin Qingyi smashed the treasure chest that symbolized the mysterious reward.

A system prompt sounds: "Congratulations to the host!" The opening of the system hyper-tech manufacturing plant is now in the first phase. ”

"Super Manufacturing Factory: A super technology factory from the science and technology star field, there is only the unimaginable, there is nothing that cannot be manufactured, mobile phones, rice cookers, computers...... Consume a certain amount of exchange points, and it can be successfully produced. ”

"Level 1 produces 10 units a day? This rate is a bit slow! ”

Lin Qingyi took a look at the efficiency of this super manufacturing factory and felt that it was useless for the time being.
