A delegation composed of Enders and others then visited the production workshop of Zhonghua Fokker Company, which is installing satellite transceiver terminal equipment for airlines.

The antenna of the satellite transceiver needs to be installed on the back of the passenger aircraft, in order not to change the aerodynamic shape of the passenger aircraft, the antenna shell is almost flush on the back, and the shell material can withstand the low temperature of minus 60 °C and the high temperature of hundreds of degrees, and can also withstand lightning strikes, and the technical content is not low.

Airbus has also done a lot of modification work in this regard, but because they produce Ku-band satellite antennas, the antennas are electrically rotated and relatively large, so the shell has to bulge out a big bag.

However, Huaxing Group uses a phased array array antenna, and the antenna does not rotate, so the shell is almost flush with the back of the aircraft, and will not bulge out a big bag.

The W-band network and data units used to drive and control the satellite antennas mounted on the roof of the aircraft, as well as several A's, are mounted on the roof of the cabin of the airliner.

For these technical products, Huaxing Group has always been very little publicity, did not engage in overwhelming marketing drafts, and did not proudly say how many high-throughput satellites they want to launch, and kept engaged in research and development to solve a large number of practical problems, and has a clear industrial development path, after spending a lot of manpower, material and financial resources, it has been able to provide a complete set of product and technical services for airlines.

China Fokker now basically undertakes more than 60 percent of the share of domestic airlines installing satellite broadband Internet access, and the total price of a complete set of equipment plus supporting software is 2 million.

China Satellite Communications Co., Ltd. provides airlines with satellite broadband services that can reach 1G data capacity, and airlines have to pay hundreds of thousands to millions of dollars a year for each aircraft.

However, this price is much cheaper than that of overseas satellite companies according to the traffic, and the price of Eagle Sauce domestic transmission of 1G data is about hundreds of dollars, the price is really expensive, and passengers can't afford it.

At present, domestic airlines basically provide membership cards to charge by the hour, almost 5 yuan an hour, and there will be certain discounts in the off-season.

Domestic airlines are now playing with this service that provides wireless Internet access.

At present, more than half of the passenger aircraft of domestic airlines have been equipped with wireless wLan equipment, and it has also created more than one billion revenue for domestic airlines for more than a year, which has become a new growth point for domestic airlines' profits.

According to this trend, the market size of domestic passenger aircraft wireless wlan will reach 10 billion in five or six years.

The European aviation market is more developed and has higher spending power, and the capacity of this market will be larger.

Seeing that Rabbit is the first in China to promote satellite broadband network services in the aviation market, this year in Europe and North America Faa, easa opens up the use of in-flight wiFi, and the aviation wiFi service launched in Europe integrates the ground base station, and provides data transmission to passenger aircraft through the link technology of L-band marsat, but the L-band marsat link can only provide passengers with 492K data transmission capacity, so the service experience can be said to be very poor, and it is impossible to achieve a smooth Internet experience of more than 10 megabits of broadband for domestic passengers like rabbits.

In the face of rabbit's domestic satellite communication technology and the rapidly expanding satellite communication market, the European Space Agency is also worried about this.

The European Space Agency also proposed to build a satellite broadband network platform similar to the Starlink network, but this matter is not a matter of shouting slogans, technology and capital are indispensable.

Who wants to spend $10 billion or two to build a backward satellite communications network?

Eagle Sauce is the fastest moving company in China, but the technical level is similar to that of Europe.

In fact, before the scene, Panasonic Group and several domestic companies of Eagle Sauce were ready to cooperate with Huaxing Group Company to build ground gateways in Neon Country and Eagle Sauce in China, and Huanyu Satellite Company, a subsidiary of Huaxing Group, provided commercial application technical assistance and gateway maintenance services.

Eagle sauce is very vigilant about this in China, because the underlying protocol standards of this network platform are all controlled by rabbits, and the domestic military has no way to monitor it, and the underlying control of this platform is in the hands of Huaxing Group Company, and the ground gateways distributed in other countries only have the right to use, and there is no way to control this Starlink network.

Because of the obstruction of the Eagle Sauce White House and the military, the agreement between Eagle Sauce and Huanyu Satellite Company has not been approved for a long time, but Panasonic Group has been approved by the Neon State Government and is now building a ground gateway.

Eagle Sauce's domestic airlines and passengers were not satisfied with the service provided by Gogo, and even sued the company to terminate the cooperation agreement and intend to bring in competitors such as Panasonic and Universal Satellite.

This is mainly the rabbit domestic airlines in the passenger plane wireless network on the service business development is too fast, and the service experience is very good, in addition to the take-off and landing stages can not enjoy the Internet service, other time periods of airlines can provide stable and reliable communication network.

In particular, domestic and international flights can enjoy a stable and reliable communication network when flying over the ocean and at different flight altitudes.

Gogo's WiFi system is so limited that WiFi is unusable when the plane is over the ocean or below 10,000 feet, and it limits bandwidth for each aircraft, resulting in slow internet speeds and high charges.

In this comparison, gogo's service is like an antique from the last century, no wonder the domestic airlines of Eagle Sauce are in a hurry.

After visiting Zhonghua Fokker, the delegation also came to Yanjing City.

When the delegation visited China Satellite Communications Corporation, the company's technical department also showed the delegation some new products of key components in satellite communication technology.

The R&D department will integrate multiple GaN monolithic microwave integrated circuits into one, the cost of the amplifier device is lower, and it has passed rigorous testing and inspection, and the performance of the device has been improved a lot and the reliability has also been improved.

Operating at frequencies up to 140 GHz and consuming up to 20 kilowatts, the device offers a significant increase in output and efficiency over previous devices.

This also means that the capacity of the communication satellite of China Satellite Communications Corporation will be further increased in the future, and the transmission capacity of the transponder will also be increased.

In the past, in order to achieve 140 GHz frequency communication satellites, a relatively mature traveling wave tube, RF power amplifier and gallium nitride device were used to work together.

Because Huaxing Group could not achieve such a high power in gallium nitride devices and space power synthesis technology at that time, it had to use vacuum traveling wave tubes to achieve such a high frequency.

Through continuous research and development in the past few years, Huaxing Group has finally developed a high-power amplifier that can replace vacuum traveling wave tubes!
