Starlink satellite is the world's first satellite to use phased array communication transmission technology, and it is also the first time to use 140g hertz UHF microwave communication technology, if it is not for Huaxing Group for seven or eight years has been conducting in-depth research on the waveform coding and algorithm of UHF microwave communication, plus Yang Jie himself is a communication expert, in his previous life in the baseband chip of UHF microwave communication to conduct various research, sometimes he will personally get started, Huaxing Group is naturally very fast in this regard.

This is equivalent to the realization of communication technology more than ten years in advance, not to mention the blessing of gallium nitride devices, Huaxing Group now recognizes the second in ultra-high frequency microwave communication technology, and no one dares to recognize the first.

In the past few years, Huaxing Group has successively made 140G hertz ultra-high frequency modulator chips and RF antennas, high-power microwave generators, and array antenna modules, and passed various tests and tests.

The Starlink No. 1 satellite array antenna module is an electrical scanning, without mechanical parts, and uses gallium nitride high-speed switch, the total switching time is shortened to tens of nanoseconds, which makes the satellite respond extremely fast, and adopts a multi-beam working mode, supports multi-beam tracking, and can track 500 high-speed moving transceiver terminals at the same time without losing signals.

This is almost an early warning aircraft moved to the air, but it is mainly used to transmit high-speed signals, no need to search for targets, only after receiving the application of the transceiver terminal to establish a connection, the connection will be established, the signal tracking will be carried out, to ensure that the link can be established at any time, and the signal strength of the beam is adjusted according to the needs of the transceiver terminal. ∵ Eight ∵ Eight ∵ Read ∵ Books, .↗.▲o

Meixihu University's School of Artificial Intelligence is also involved in the project, developing a set of intelligent algorithms to make satellite signal transmission more efficient and intelligent.

The research and development of such a satellite is also the use of the cutting-edge technology of Huaxing Group Company, this satellite can be regarded as a masterpiece, but also a revolutionary satellite product!

Huaxing Group company's scientific research has always dared to think and dare to do, with a good product technology concept, it is immediately started to carry out research and development, with a sense of urgency, and research and development needs some special instruments and equipment Huaxing Instrument Equipment Company will immediately start to develop and produce, will never delay the progress of research and development.

Of course, in the past few years, the research and development of this satellite has also encountered a lot of technical problems, but with the support of more than 100,000 technical engineers from various technical fields and a large number of technical patents of Huaxing Group, these technical problems have also been overcome one after another.

The production management standard system of Huaxia Satellite Communication Company is also strictly in accordance with this set of process standards for the design and production of satellites by Motorola and the standards that Huaxing Group has explored over the years, and this set of standards is also to ensure that the quality and performance of satellite products are very reliable according to this set of process standards.

Because a lot of new technologies and new materials are used, if they are replaced by other companies, these satellites will basically be sky-high.

However, these core components provided by Huaxing Group to Huaxia Satellite Communications Company are all provided at internal cost prices, because there is no way to recover the cost of these satellites alone, and they can only make money back from the software services of ground transceiver terminals.

So these five satellites are basically the cost price, and the price has been pushed down to four million dollars.

With the help of Motorola's company, Huaxia Satellite Communications Company has established an automated production line with a clean room, using a lot of robots, and these satellites are assembled on the assembly line like producing cars, which is also the first time that a domestic company has done this, and it also ensures that the assembly line can produce at least three satellites a week.

In Yang Jie's memory of his previous life, Motorola's Iridium program is also a miracle in technology, breaking many of the so-called rules for manufacturing spacecraft, basically using satellite devices produced by themselves, without any complete space quality qualification or certification, and the other is to move the production assembly line, and these satellites can be launched by almost every space-faring country with launch capabilities, the most important thing is that these satellites are designed to work for five years, and in the previous life, these satellites worked for twenty years and are still working effectively。

This shows that Motorola is really good at quality control in electronic and electrical engineering technology!

Huaxia Satellite Communications Company also learned a lot from these satellite experts and engineers sent by Motorola, and they all strictly followed the process standards for production.

Yang Jie is quite assured of the quality of the satellites produced by the satellite production line of Huaxia Satellite Communications Company.

It took almost two hours, and the upper stage intelligent distributor released all five satellites at different positions in five orbits, and these five satellites basically covered the entire territory of Huaxia, and the signal relay between the satellites would not be interrupted.

By the next morning, the five high-speed communication satellites had all been activated, and the ground control station was also undergoing various tests and adjustments before the networking.

Yang Jie attaches great importance to R&D efficiency, but the process must be meticulously repeated, until it is determined that a complete set of ground control stations and satellite networks in space can remain stable and reliable under some extreme conditions, and the first phase of the Starlink project is completed.

In the afternoon, Yang Jie also participated in the celebration banquet held in the Sky City.

This time, Yang Jie was very happy in his heart, and he also specially asked the secretariat to invite a well-known chef to this celebration banquet, and brought top ingredients to reward all the staff involved in the launch, and held a free lottery and prepared various gifts.

Such a banquet also made everyone smile.

This kind of celebration banquet is also a place for the people of the Aerospace City to experience the boldness of Huaxing Group to treat its partners.

Huaxing Group is not only rich, although Huaxing Group has very high requirements for suppliers, and the R&D system and management are very similar to Western companies but very different, but as long as the standards are met, it is really willing to spend money.

After the celebration banquet, the crown prince of the caliph originally wanted to follow Yang Jie to the ground control station in Xi'an, but because there was something to deal with, he had to leave by special plane. 11
