We have long been accustomed to seeing all kinds of pictures of the earth taking pictures from space, but we often forget how complicated it is to observe the earth.

In fact, doing anything in space is difficult, let alone trying to capture high-resolution, high-precision surface images.

This is indeed awesome for digitalglbe satellites;

DG's Earth Imaging Satellite can capture images with a resolution of 30-50 cm from a height of about 700 kilometers above the ground;

What does it mean? It’s like taking a photo from the Oriental Pearl Tower of the China Sea, you can see a car on the Wuhan Yangtze River Bridge.

dgThe awesome things are more than that.

The satellite that took this photo was flying at a speed of about 27,000 kilometers per hour, which was equivalent to arriving from Yanjing to Taiyuan within minutes.

It is very difficult to keep the camera stable at such shooting speed!

In addition, the launch of the DG satellite is also a very difficult task, and the orbital window it occupies is about 2 square kilometers;

It is difficult to put a satellite in that small piece of space safely than shooting a football into a truck tire from as far away from seven football fields;

Moreover, each satellite weighs 3 tons, the size of a small school bus;

From here you can know that American DG is not unreasonable.

Whether it is our domestic whiteness, Gaode, Tengxun, Apple, Google, these map images are all from DG.

At the same time, many companies such as Uber and Faebk that provide positioning services are also DG customers.

Of course, saying so much is not to show that DG is powerful, but to want to make such a satellite and send it to space. In addition to technology, the most important thing is ney, a big ney~

Adding 300% to the highest 300% forecast of $150 million, nearly $500 million;

Even if you consider R&D costs, it will cost more than US$300 million just to send one to the sky.

According to the global coverage frequency, 3-5 are launched, and here are hundreds of millions of US dollars.

Technology, money, and various relationships are in place. Do you think you can launch satellites?

wrong,

There is still a queue!

You have to queue up for dinner, and you don’t have to queue up to launch satellites?

As for when you will be ranked, it depends on luck.

Nowadays, domestic and foreign commercial companies are busy sending small satellites to the sky, and the schedule is full. If you are lucky, you will be able to get there for three or five months, but if you are not lucky, you may be able to get there for a year or two years.

hat the fuck?

I'm ready for everything, but I'm not going to have the east wind. You've asked me to wait a year or two?

pass~

So, after thinking about it, Han Yi thought of launching a "nano satellite".

Nanosatellites are small satellites with mass between kilograms and 0 kilograms, and use a 0x0x0 unit cubic structure.

The most convenient thing about nanosatellites is that they are simple to launch, and they can be launched together by "hiking a car" on the rocket;

The launch time is 3-0 weeks, and the price varies depending on the weight of the satellite and the distance of space, ranging from 300,000 US dollars to 00,000 US dollars, and the maximum will not exceed 2 million US dollars per.

...

Dare to do it when you think of it

The first is the aerospace camera.

Aerospace cameras must withstand the violent vibrations when rockets are launched;

We need to take clear images of the ground through the atmosphere from hundreds of kilometers or even thousands of kilometers away from the ground, in an environment of ice and fire, and on tracks without tripods and bean bags.

Currently, there are only a handful of people in the world who are capable of manufacturing aerospace cameras, and the top ones are just a few days.

There are no aerospace cameras on the market, they need to be ordered from the manufacturer, and the price is high.

Leave this matter to Suriel to contact, and Han Yi then went online to find a DIY expert to buy nanosatellite models.

There are many people doing this in private, and even some rich people spend money to launch it into the sky. It’s just that it’s not a remote sensing satellite, but it’s not a large commercial monitoring satellite.

Finally, I contacted a seller in Yangcheng online. The other party offered a price of RMB 1 million, but did not bargain, and had to pick up the goods at home.

Han Yi didn't think much about it and agreed to deal in person in three days.

After contacting the shell part, the next step is to prepare various auxiliary materials.

I drove to the hardware market to order a large number of sensors, solar panels, memory and other items.

After getting this done, Han Yi asked Suriel to make an appointment with a satellite launch company in advance.

At several launch sites in China and neighboring countries, the "boarding service" will be scheduled for 3 months;

Finally, I asked around and found the United States again.

p's...

The company is called spaeflight. In Seattle, USA, they can provide services, and they are affordable and cheap. If they don’t provide additional “bundle services”, it only costs $500,000. Make an appointment now and go to heaven within three weeks.

Bite your teeth, pinch your nose, and admit defeat~

Sony responded quickly and replied in the afternoon of the email, willing to provide them with aerospace cameras for $400,000 and arrive in one week.

purchase!

...

At noon the day before National Day, after preparing everything, Han Yi went to the company.

When he came back, he was about to walk along the river road, but Yu Jingyao called and asked him to take her to the Jade Garden. Han Yi asked Zhao Hongwu to turn to the Conservatory of Jin Normal University.

When he arrived at the Industrial and Commercial Bank of Yanjing Road, Han Yi asked Zhao Hongwu to stop the car.

Because the seller in Yangcheng said that cash transactions are needed, he doesn’t have that much, he needs to withdraw a little.

Han Yi is a platinum customer of ICBC. He didn’t have any reservations. When he arrived at the big customer room, he lit the card and drank coffee and waited for money.

The speed was very fast. About 20 minutes later, the account manager came over with a large bag of cash, and there were two security guards waiting to escort outside the glass room.

"Mr. Han, I've been waiting for a long time~" the account manager was enthusiastic.

"fine."

Han Yi put down his coffee and was about to leave when he saw a man with a familiar face passing outside the glass room and heading towards the business window at the bank counter.

Han Yi went around half a circle to the other side to observe carefully, and the familiar feeling became stronger and stronger;

Then he suddenly remembered that the other party was just a Tianyi employee. The last time he went to the construction site of Xiling Town, the other party reported to him about his work, but he couldn't remember what his name was.

"Why is he here?"

In a puzzled manner, Han Yi said to the account manager next to him: "Help me see which company is in the account window?"

"Okay, Mr. Han wait."

The account manager is coming quickly and comes quickly. He came in less than 2 minutes.

"Mr. Han is a company called Deye Building Materials Co., Ltd.."

"Okay, thank you~" Han Yi didn't ask the other party's name or what he was doing in the bank. It was enough to know the company's name.

The security guard helped him deliver the money to the Mercedes-Benz trunk parked at the door.

After getting on the bus, Han Yi called Tianyi's "International Business Intelligence Analysis Center" and said, "Which upstream buyer is helping me check the building materials of Chadye?"

When the bus arrived at the south gate of the Conservatory of Music, the phone came in.

"Boss, Deye's buyer is a bag company called Jianjia Trading, and Jianjia is an offshore company registered in Shenzhen City, and the legal representative is Feng Xiangxue."

A small bag company has gone through so much effort to make it so complicated, so the subsequent problems must be very serious.

Han Yi said coldly: "Continue digging down~"

"Okay, boss~"

…………

After following Yu Jingyao, he went back to the Jade Garden directly.

Because He Xiaoxiao had just arrived in Yanjing, she did not return to Jinling last week and said she was waiting for her return on National Day.

However, He's mother is here, and there are two other nannies. Yu Jingyao is here basically every night, so she doesn't have to worry about no one taking care of the big cat and kitten.

By the way, Geng Kailin often comes over.

When I got home, the setting sun was setting, and a golden light passed through the French sycamore planted in the community, which was particularly beautiful.

As soon as he got off the car, he came and asked Yu Jingyao to enter the house first. Han Yi sat in the car and picked it up.

"I found out that Feng Xiangxue is from Xiangjiang. We found through her mobile phone number that she often contacted a man named Li Yu in China;

And Li Yu also runs a trading company, which has only one customer, called "Wanqi Heshuo".

Han Yi couldn't help laughing, "There is no loofah vine?"

"Uh...no more. Wanqi Heshuo..."
