"Brother Yang Jie, after these four high-speed communication satellites are launched this time, how long will it take for you to officially put them into operation?"

The Crown Prince of the Caliph asked.

"If the satellite is successfully launched this time, we need to carry out a variety of technical verification for more than a year, if we encounter various problems, we also need to make various technical adjustments, and it will take at least two to three years if it is long, if it goes well, the satellite launch will enter an intensive launch period at the end of next year, and I hope to complete the launch of 60 satellites in more than two years, and initially complete the global coverage. ”

"I hope that within ten years, this satellite network will have more than 100 satellites in orbit, and I hope that with the reduction of satellite manufacturing costs and launch costs, more satellites will be launched in the future. ”

Yang Jie said to the Crown Prince of the Caliph.

"Brother Yang Jie, the UAE's Suraya Satellite Communications Company now only has two geostationary orbit mobile communication satellites, these two satellites were built by Boeing, and they are indeed much behind you in satellite communication technology. ”

The two satellites mentioned by the Crown Prince's caliph are the world's first communication networks that creatively integrate the three functions of satellite, digital communication network and GPS, and can provide a communication system that provides five services: voice, text message, Internet access, fax and GPS positioning.

When the user using the Suraya communication system can use the terrestrial cellular communication service to make mobile phones in the terrestrial network coverage area, and once the user leaves the traditional terrestrial communication network coverage area and comes to a remote area, his mobile phone will automatically switch to satellite communication mode. Therefore, whether the user is in the city, town, or to the countryside and remote areas, or at sea, can use handheld communication equipment, with the help of the Sulaya communication system, fast and convenient voice and data communication.

However, the communication capabilities of these two communication satellites are similar to Motorola's Iridium system, and the so-called data communication is to provide a data transmission rate of 384K, or allow customers to enjoy the function of remote connection, which can be connected to the enterprise network, update or access company and customer information from time to time, and the other is the function of sending emails and file transfers.

However, when the Crown Prince of the Caliph visited the Huaxia Satellite Communications Company, he learned that the total data capacity of such a small satellite developed by this company reached an incomparably astonishing 1200g!

And Huaxing Group seems to have adopted a new network topology architecture, each of these communication satellites is a node, because these satellites are moving at high speed, when the satellite flies over the ground receiving station, it will automatically join the network, when the node leaves the network, the rest of the nodes can automatically reroute other satellites, to ensure that there is a more reliable communication path.

Moreover, this technology allows data from one node to be forwarded through multiple remaining nodes before it reaches a ground gateway, without sacrificing the current channel capacity, maximizing coverage, requiring only short-distance communication links, and experiencing less interference, thus providing a very high throughput rate and high spectrum reuse efficiency for satellite communication networks.

Due to the existence of multiple routing paths between the nodes of the satellite network structure of the Starlink plan, the network has strong fault tolerance and robustness to single point or single link failure.

The biggest advantage of this network structure is that although all nodes are equal and have the same computing and communication functions, one node can be designated as the cluster leader node and can perform additional functions, and once the cluster leader node fails, another node can immediately supplement and take over the additional functions performed by the original cluster leader.

Naturally, the crown prince of the caliph did not know that this network topology architecture was a technical solution proposed by Yang Jie, and it took Huaxia Satellite Communications Company and Huaxing Group Company nearly two years to realize this technical solution.

Although it is not known how Huaxing Group did this, the technical prowess displayed by Huaxia Satellite Communications Company when it demonstrated to the crown prince of the caliph also frightened the latter.

Therefore, the crown prince of the caliphate also came to participate in the first launch of the four satellites of the Starlink program this time.

The Sulaya satellite system covers 80 countries and regions including China, Australia, North Korea, Europe, North Africa, Central and South Africa, the Middle East, Central Asia, South Asia, etc., covering nearly one-third of the world's regions, and can provide cost-effective satellite communication services for sea and land mobile users of more than 2 billion people in these countries and regions, and its business scope covers mobile voice, broadband, maritime, rural telephone and other communication services.

However, this Starlink plan can provide customers with a high-speed transmission rate of more than 1G, which is hundreds of times the transmission rate of existing satellites!

With such a satellite high-speed communication satellite comparable to the high-speed broadband capability of optical fiber, the business of the previous communication satellite has been expanded.

The technical team of the crown prince of the caliph has also calculated that a high-speed communication satellite with such a large capacity can provide 2 trillion bandwidth Internet services to more than 30 million users after it is put into operation, and the network delay is controlled at 45 milliseconds, which has fully met the requirements of many gamers for some fighting and shooting game input delays.

At this stage, the network delay of the Internet is basically 160 milliseconds, and if the network is not good, the delay can reach more than 188 milliseconds, but Huaxia Satellite Communications Company can control the network delay at 45 milliseconds, which is really a technical miracle!

This is due to the new coding method of polar code proposed by Yang Jie and the topological architecture scheme of the satellite network, which makes the network delay of this satellite network reduced to a very amazing degree during ground testing!

The crown prince of the caliph did see with his own eyes at the ground test station that the response speed of the exquisite ground mobile terminal equipment launched by the Huaxia Satellite Communications Company is really fast, although the actual situation of the high-speed communication satellite after entering the designated orbit is not much different from this.

In fact, Dubai is also the main sponsor of the Sulaya satellite system, but the data transmission capacity provided by the satellite is still very weak compared to the Internet broadband belt, and now the Huaxia Satellite Communications Company has made such a starlink plan, which can provide high-speed Internet access services for ships, airplanes, cars, trains, etc., and can provide communication services for areas that cannot be reached by terrestrial communication networks and optical fiber broadband.

If deployed, this network will already have a new satellite communications network that will provide high-speed Internet access to the world's billions of other consumers who do not have access to broadband.

The Starlink-1 satellite developed by Huaxia Satellite Communications Company is the world's highest bandwidth satellite, although the Crown Prince Caliph does not know how much the manufacturing cost of such a satellite is, but in recent years, Huaxing Group must have spent at least 400 million US dollars on it.

Although the platform of such a high-speed communication satellite is a mature satellite platform, it also uses a lot of high technology, and the cost of the first batch may be very high, but as long as it is on the scale, the manufacturing cost of the satellite will naturally be reduced to a very low level.
