Yang Jie looked at Chris and said, "I know that your company is very experienced in the design and production of small communication satellites, I wonder if your company is willing to cooperate with us to develop a new small communication satellite platform?"

Chris glanced at Yang Jie in surprise: "Your company is going to enter the field of satellite communications?"

"Yes, I plan to build a global low-orbit communication network to provide high-speed satellite broadband to customers around the world, and I have formed a company to conduct related research and development. ”

Yang Jie looked at Chris and said: "If Motorola is willing to provide us with satellite platform technology, we can purchase such satellite platforms from Motorola in bulk, and if your company is willing, we can also cooperate with ground terminals and mobile terminals." ”

Chris's eyes widened: "Mr. Yang, please forgive me, I am not very optimistic about your satellite high-speed communication broadband network. ”

Motorola's subsidiary, Iridium, went bankrupt two years ago, leaving Motorola with billions of debts.

"Mr. Chris, if you were aware of our plans and technological advances, I think you'd change your mind. ”

Song Manli said at this time.

“......”

Chris glanced at Song Manli and Yang Jie suspiciously, and said, "You mentioned satellite high-speed communication broadband technology just now, are you solving the technical problems of satellite high-speed communication?"

"Hehe, to be honest, our Huaxing Group has made a breakthrough in W-band microwave transmission technology, and now it can be said that the communication transmission technology of this band has been relatively mature. The communication capacity of a signal transponder we developed can now achieve a transmission capacity of 100G, and now the satellite we developed and designed is equipped with 12 transponders, with a total capacity of 1200G. ”

The year before last, Huaxing Group used gallium nitride technology to achieve the transmission rate of a signal transponder in the laboratory to 5G, almost two years later, Huaxing Group of these communication experts and mathematicians have made a great breakthrough in the research of waveform coding algorithms and adaptive antennas, and the transmission capacity of the signal transponder has been increased by 20 times!

Because Yang Jie put forward modular requirements for Huaxia Satellite Communications Co., Ltd. in the development of satellites, requiring the satellite platform to use an open architecture, China's modular spacecraft will soon start space tests, and the outstanding feature of modular construction is the use of open architecture, which can be added on the basis of the basic architecture of the center, such as communication, meteorological detection, navigation and positioning.

According to his requirements, according to the modular division standard, the satellite as a whole is divided into a plurality of functional modules, each functional module is an independent whole, can independently complete one or more tasks, each functional module adopts a standard unified interface, and the functional modules produced by different manufacturers can be compatible with each other in mechanical, telecommunications and data interfaces, and can be assembled more conveniently.

The open architecture design of the satellite is mainly handed over to these experts and technical teams from the space group to complete, and now the design of this open architecture satellite has produced a prototype, and the mechanical, telecommunications and data interface standards have been confirmed, and there is no need to make significant changes to the satellite platform itself because the product technology upgrade is too fast.

Huaxing Group is mainly responsible for the research and development of signal transponders, power supply systems, air interface technology, satellite broadband architecture, and ground terminals, and these experts and technicians from the aerospace group are responsible for the research and development of satellite platform open architecture, tracking telemetry instructions, and control systems.

The speed of upgrading the technology of the satellite platform is much slower than the upgrade speed of these functional modules on the platform, and Yang Jie took this problem into account before the start of this project.

"......" Chris and the two vice presidents who came over with him all showed shocked expressions, they never dreamed that Huaxing Group Company would achieve such a degree in satellite communication, and they all suspected that they were having auditory hallucinations, or these Chinese people in front of them were joking with them.

The data transmission capacity of a satellite can exceed 1t, and now the transmission speed of international optical cables can break through this level.

One such satellite is enough to meet the needs of tens of millions of people to enjoy high-speed Internet access.

Yang Jie saw that Chris and the others had a look on their faces that could not digest the news, smiled, and said, "In this way, tomorrow I will accompany Mr. Chris to visit our W-band data transmission test site......"

"No, now I can't wait to see your test equipment!"

Chris interrupted Yang Jie's words at this time and said excitedly, as if he couldn't wait for a second.

Yang Jie exchanged glances with Song Manli, Uncle, Hu Huanzhi and others, all with smiles on their faces.

In the afternoon, at a ground test receiving station, Chris saw that the oscilloscope showed a band of only one millimeter, an uplink frequency of 120GHz, a downlink frequency of 80GHz, and a download rate of an astonishing 14G, and this transmitting base station was hundreds of kilometers away!

Chris also deliberately went indoors to use a handheld terminal to check the signal, and he found that the signal strength received indoors was still very good.

"Mr. Chris, the electromagnetic wave penetration ability of this band is very strong, and the degree of signal blocking attenuation is relatively light in many places in the building. ”

Luo Zhen said to Chris with a smile.

"Unbelievable, how did you do that?" said Chris, shocked.

"Hehe, we have made a good breakthrough in gallium nitride materials, and we have studied a lot on high-frequency microwaves, so we can do this step. Luo Zhen said proudly, as for how to do this, he naturally won't reveal it.

Chris took a deep breath and said to Yang Jie, "Mr. Yang, let's talk about your Starlink network plan......

The W-band high-speed transmission technology demonstrated to Chris by Huaxing Group has completely convinced several of these Motorola executives, and they also see the potential commercial benefits brought by this Starlink plan.

Chris knows that this Starlink project is quite similar to the Iridium project led by his father, but the Iridium project can only provide the function of making calls and communication, but Huaxing Group has been able to achieve a transmission rate comparable to that of a fiber optic network, and the gap between the two is very large.

The Iridium project began to be prepared in the late eighties, and the three scientists involved in this project were all more or less involved in the previous Star Wars program in the United States before that, from the concept of '87 to the official launch of the project in '89 to the launch of the satellite in '97 to the completion of the satellite launch in '99, which was ten years in between, compared with the digital communication network in terms of communication technology.

Moreover, Motorola's market positioning has also deviated, and it is naturally thankless to use Iridium mobile phones to enter the price-sensitive consumer mobile phone market.

"Mr. Chris, in our program, we are targeting customers such as aviation, ships, railways, automobiles, news organizations, and exploration and research agencies. ”

Yang Jie said with a smile: "My idea is to open up the Internet, mobile Internet, and Starlink networks to achieve seamless links, so that passengers in the transportation industries such as aviation, ships, railways, and automobiles can enjoy high-speed Internet access services." ”

"There are now more than 100,000 flights flying around the world every day, and these millions of consumers are not able to enjoy the experience of high-speed Internet access, and there are hundreds of millions of customers who fly every year, which is a very huge market. Similarly, rail trains and ships are also excluded from these services, and if we can open up this market, it will not be a problem to make money. ”

Yang Jie said with a smile: "With this network, we can also provide a variety of services, for example, we can use satellite tracking technology to provide navigation services for aircraft around the world, because the ground radar will not always track the aircraft, generally only when the aircraft is flying over land, it can keep in touch with the air traffic controller through the radar, transmit relevant flight information, and once the aircraft flies 100 to 150 miles offshore, the aircraft will enter the "program airspace" Air traffic controllers must rely on pilots to report the aircraft's position every 10 minutes. We can use this to allow airlines to fly more non-stop routes, which can reduce the cost and time of air travel. ”

"In addition, this can also be used to provide information about the position, speed, altitude and other information of the aircraft for air crash investigations, and it can also provide faster rescue operations. ”

Yang Jie said: "Although Motorola's previous Iridium program has been stopped, it is very groundbreaking from the technical level, and I have also received a lot of inspiration from this program. ”

He looked at Chris and said: "Mr. Chris, your father is the initiator of this plan, although this plan has been frustrated, but Motorola has also mastered a lot of advanced technology in satellite through this project, and I very much hope that you can also join the construction of this Starlink network." ”

"I am very impressed by a lot of Motorola's technological innovation in the design and manufacture of satellites, and you have been able to compress the production time of satellites to the level of producing at least two satellites a month, which is very engineering and technical. ”

Chris smiled: "We still have a lot of talented engineers within Motorola. ”
