Chapter 288 Luxshare Precision in the Satellite Industry

"Impossible, absolutely impossible!"

"What a joke!"

"Do you think everyone is an idiot? How can a small satellite with limited payload achieve such strong performance data... Even if the high-definition resolution can reach 0.5 meters, a single scene shooting can still achieve an image of 60*70 kilometers?!"

"Fake news! These data are definitely false!"

"Oh my god, the revisit rate of a single satellite has reached 72 hours, which is nearly 24 hours faster than ordinary remote sensing satellites! If their satellites are connected to a multi-satellite network, it is not possible to achieve a revisit rate of less than one hour...

…?”

As soon as the news came out, many commercial satellite manufacturers flatly denied the news. They knew all too well how difficult it is for "small remote sensing satellites" to have such technical performance!

Unlike communication satellites that pursue stable communication signals and fast transmission speeds, for "remote sensing satellites", the most important performance is to have sufficient image collection capabilities.

To put it simply.

Because the satellite is always orbiting the earth, it is impossible to stare at a certain area on the earth and take pictures continuously. Therefore, this requires the satellite to collect as much as possible, quickly and clearly when it reaches the "mission collection area".

Map information in the mission area.

but.

As we all know, the wider the shooting range, the more light and shadow data the sensor receives, and the clarity of the picture will naturally decrease.

According to the existing technology, the shooting range of general remote sensing small satellites is about 50*50 kilometers wide, and its purpose is to ensure the clarity of remote sensing pictures!

And what about the "Viewing No. 1" announced by "Happy Planet"?

Good guy, not only does the single-scene shooting area reach 60*70 kilometers, but the resolution also reaches an accuracy of 0.5 meters?!

How is this done?!

It would be fine if multiple optical instruments were used on a large satellite, but this is a small satellite that only weighs 520KG!

Industry experts suddenly fell silent.

certainly!

If the imaging ability were just stronger, everyone in the industry wouldn’t be so surprised!

Experts in the industry immediately discovered another data that surprised them, that is, the data downlink rate of "Guanjing-1" exceeded the 2-thread 2*450Mbit/s of ordinary remote sensing satellites, reaching 4*450Mbit/s.

s!

What is the data downstream rate?

To put it bluntly, it is the speed of downloading data.

Perhaps in the eyes of ordinary people, the download speed of 450M per second with dual threads is already very fast, but in fact, the 2*450M data downlink data of ordinary remote sensing satellites has gradually been unable to meet the actual needs of existing remote sensing satellites!

Nowadays, the photos taken by better mobile phones are tens of MB in size. You can imagine how much data a remote sensing satellite photo of 60*70 kilometers with a pixel accuracy of 0.5 meters will be!

It is at least a few hundred GB in size, and this is just a picture!

Such huge data ultimately needs to be transmitted to ground signal service stations by satellite signals, and the most terrible thing is...

There is a window period for stable data transmission between remote sensing satellites and the ground!

Because satellites are orbiting the earth all the time, satellites and ground signal receiving stations (Tianguo) have signal strength and weakness cycles.

Under normal circumstances, data transmission will only be started when the satellite and the ground service station achieve a strong signal connection, that is.

If during the transmission window period, there is too much data and the transmission downlink speed is not fast, and all the data on the satellite cannot be downloaded to the ground during the window period, then you can only wait for the next strong signal before transmitting.

This situation is not only troublesome, but the satellite will basically suspend all shooting missions before downloading again.

Why?

Because the storage space on the satellite is limited, you can only shoot a batch of data, transfer a batch of data, and then shoot again!

And now the "Viewing No. 1" announced by "Happy Planet" not only has strong shooting capabilities, but also has a storage space of 5T on the satellite. The most important thing is that it has a data transmission capacity that is more than double that of other remote sensing satellites!

In other words, "Guanjing-1" can take several more pictures and transmit more pictures to the earth than other remote sensing satellites in the same time.

This collection efficiency and speed are completely twice as high as other remote sensing satellites!

Thinking of this, industry experts are in complete disbelief.

Several important indicators that determine remote sensing satellites: shooting width, on-board storage capacity, data downlink capability and maneuverability. At present, in addition to maneuverability, the "Viewing No. 1" developed by "Happy Planet" has actually achieved industry-wide

Leading?!

This is the development direction of small remote sensing satellites that everyone dreams of!

Damn it!

At this moment, the well-known domestic commercial satellite manufacturers, "Tianyi Research Institute" and the rising star "Time and Space Daoyu" satellite company, simultaneously issued a burst of urgent instructions.

"Hurry up and contact Happy Planet and learn about their technology!!!"

…

the other side.

Aerospace Group Headquarters.

Luo Yongheng, the head of the aerospace group, frowned as he looked at the latest industry information.

"Single satellite revisit rate is 72 hours, downlink data 4*450Mbit/S..."

"'Happy Planet' Satellite Company?"

The leader, Luo Yongheng, frowned even more tightly. He looked at the news carefully again, and finally put down the phone in his hand and murmured:

"I've never heard of the company 'Happy Planet', and it's not even a member of the Commercial Aerospace Association. How come it suddenly has such a huge technological breakthrough?"

"Hey, I don't know if it's true or not!"

After thinking for a moment, Luo Yongheng still couldn't help but feel a little curious. He picked up the phone on his desk and called his secretary Zhang Hao.

"Xiao Zhang, please come in."

After a while, Zhang Hao walked in with a charming smile.

Before Zhang Hao could speak, Luo Yongheng directly handed Zhang Hao the latest information about "Happy Planet" on his phone, frowned and said:

"Xiao Zhang, you are here. There is news that you need to verify."

"This satellite company called 'Happy Planet' recently launched a satellite. Please go find out if their satellite parameters are the same as what is said in the news."

Zhang Hao Secretary Zhang took the mobile phone from Mr. Luo with a surprised look on his face. He had never heard of the "Happy Planet" satellite company.

He took the phone and looked at it. He looked a little surprised at first, then laughed and said decisively:

"Mr. Luo, this is impossible."

"I have never heard of this 'Happy Planet' satellite company. How could it suddenly come up with such an advanced small satellite? If you ask me, it's probably fake data from fake news reports..."

Luo Yongheng also somewhat agreed with this statement, nodded and said:

"It's possible."

"However... although the current news media is not reliable, you should verify this news."

"good."

Seeing Luo Yongheng's insistence, Secretary Zhang had no choice but to agree.

He had just put his phone back on his desk and was about to leave when Mr. Luo's voice came to his ears again.

"By the way, Secretary Zhang, didn't Phoenix Group take over our Ka-band a few days ago? Have they contacted us recently?"

"Also, you said before that the Phoenix Group had the idea to purchase our Gaofen-7 satellite. How are the talks going now?"

As soon as Luo Yongheng finished speaking, Secretary Zhang suddenly felt a thump in his heart.

Somehow, he suddenly remembered that Director Zhang came in person more than a week ago, hoping that the aerospace group could help customize and produce a satellite.

At that time, I had just heard that Phoenix Group had taken over the group’s Ka-band, so I directly rejected Director Zhang’s request...

Won't……

Suddenly, the hair on Secretary Zhang's body stood up, his heart was pounding, and a huge idea suddenly emerged in his mind.

Thinking back to the news that Mr. Luo showed him just now, an unknown "Happy Planet" satellite company suddenly customized and produced the "Guanjing-1" satellite for a customer and successfully launched it...

Good guy.

Isn’t this custom customer the Phoenix Group?

The "Guanjing-1" satellite could not be the satellite that the Phoenix Group came to customize for itself, right?

Thinking of this, Secretary Zhang quickly glanced at Mr. Luo with a guilty conscience. After thinking for a moment, he gritted his teeth and said:

"Mr. Luo, Phoenix Group has canceled their purchasing plan...and they haven't contacted us during this time."

Mr. Luo frowned slightly, seeming a little confused.

However, after thinking for a while, Mr. Luo still said calmly:

"Okay, you go and do your work first."
