Huaxing Group also provides high-precision hydrogen atomic clocks to the Beidou navigation system, which greatly improves the timing accuracy of the Beidou navigation system, and the technical standards in all aspects are even more advanced than the EU Galileo navigation system.

Now the domestic satellite spaceborne atomic clock has fully adopted the domestic atomic clock, of which Huaxing Group is the best in the technical level of the atomic clock, the rubidium atomic clock used in the Starlink network is its own product, and the atomic clock is also used on the base station and server.

Huaxing Group Co., Ltd. as an important supplier of Beidou navigation system, Yang Jie also pointed to the Beidou navigation system research and development chip to enter the market, he hopes that the European Space Agency can take the initiative to relocate to other channels.

But he only thought about it this way, the Europeans of this Galileo navigation system frequency was finally obtained from the hands of Eagle Sauce, and the technical design has long been carried out according to this frequency, if it is moved to other frequencies, many designs and equipment will have to be re-modified, and this frequency is the best, they will never give up.

Yang Jie also learned that during this negotiation, the two parties were both lip and tongue, and the fierce confrontation was wonderful.

As for the Europeans' request for the domestic space agency to move the "Beidou" No. 2 system to other channels, China certainly refuses to do it.

The internationally accepted principle of satellite launch frequency has always been "whoever uses it first, who gets it first", and now that China has obtained the ownership of this channel resource, it is naturally not willing to give up an inch of its own rights and interests.

The delegation of the European Space Agency had no choice but to leave in a huff.

Yang Jie, who was accompanying Bai Bing and his son in Tanzhou City, was also called to Yanjing City by a phone call.

In a conference room, Song Xinyang, Zhang Haiping, and officials from the Aerospace Science and Technology Corporation and the Space Administration all came.

"You must know about the negotiations between the European side and us about the frequency of the navigation system?"

Song Xinyang looked at Yang Jie and asked.

Yang Jie nodded: "Chief, what can I and my company do this time?"

Song Xinyang glanced at Zhang Haiping, who said: "The central government has decided to speed up the global construction of the Beidou navigation system and strive to complete this task within three years. ”

Yang Jie was also surprised when he heard this - it seems that the attitude of the central government and the military towards the construction of the navigation system is very urgent!

The negotiations between the European Space Agency and China have also made the high-level bigwigs determined to complete the layout of the global Beidou navigation system as soon as possible, so that the European Galileo navigation system has no way out.

With this system, this is also a huge boost to the group's weapons defense export business, which can make the exported precision-guided missiles and zhà dàn have an additional guidance mode and hit more accurately.

At the same time, Huaxing Group can also open up a new market in this navigation system network.

"We, Huaxing Group Company, resolutely complete the tasks assigned to us by the central government!"

Yang Jie said with a firm face.

A few days later, Yang Jie followed the military boss Zhang Dingkun to the command center where the North Sea Fleet was located, and the commander of the North Sea Fleet, Rear Admiral Su Wuhai, and others came up.

"Yang Dong, I have heard of your name for a long time, and today I can finally see your honor. ”

Su Wuhai shook hands with Yang Jie and said.

General Su was polite. ”

Yang Jie said with a smile.

Zhang Dingkun opened his mouth and said, "Has the exercise started?"

He spoke with a Sichuan accent.

"Everything is ready, just waiting for your order, Chief. ”

Su Wuhai said with a smile.

"According to your established plan, I came here this time to see the product and technical strength of Honghu Shipbuilding Company. ”

Zhang Dingkun waved his hand, and then walked into the command center with Yang Jie and others.

The command center of the North Sea Fleet has a huge display screen, which is the North Sea Fleet's surveillance system, and there are many monitor screens displayed on the large screen.

The exercise was the first life-saving bell exercise held in the Bohai Sea region, and simulated the contents of a drill in which a submarine broke down and sank to the bottom of the sea, and the navy dispatched a life-saving bell to rescue it.

This set of life-saving bells was developed, designed and manufactured by Honghu Shipbuilding Company on the basis of deep-sea submersible technology, and after it was delivered to the North Sea Fleet, the North Sea Fleet also conducted the first rescue exercise of the life-saving bells.

Since the life-saving bell was being used for the first time in China, all the officers and men participating in the exercise had already undergone 22 operations and 36 on-site docking trainings, but at this moment they still did not have a firm grasp of it, and some even showed all kinds of concerns.

At this time, a submarine had already dived to the bottom of the sea at a depth of more than 60 meters, and at the same time released buoys and communication systems to send out a distress signal.

At this time, on the lifeboat, the medical personnel wearing white coats were on standby at the entrance of the hyperbaric oxygen chamber, stretcher, and diving ladder of the ship, and the pilots of the carrier-based helicopters of the aviation unit also entered the wheelhouse early and were ready to rescue at any time.

After a while, several life-saving bell controllers and several divers entered the life-saving bell in turn on the large screen of the command center, and began to check the air tightness, close the upper round door, and disengage the meshing......

After a series of meticulous preparations, the life-saving bell, towed by a giant ship crane and a deck winch, slowly dived into the sea and began to dock with the "wrecked" submarine.

The life-saving bell designed and manufactured by Honghu Shipbuilding Company is composed of five parts: the bell body, buoyancy adjustment system, electronic control system, hydraulic system and life support system.

The upper chamber of the bell body is the rescue manned cabin, and the lower chamber is the rescue cabin of docking with the submarine rescue platform under normal pressure in the life-saving bell; the buoyancy adjustment system is mainly to adjust the buoyancy of the life-saving bell when it is in working state, and the adsorption force of the counterpart platform with the "wrecked" submarine; the electronic control system needs to be controlled electronically when the operation is completed; the hydraulic system is an important system for completing the operation of each stage of the rescue of the life-saving bell; and the function of the life support system is to ensure the atmospheric pressure environment space in the upper chamber of the life-saving bell.

Different from foreign life-saving bells, Honghu Shipping Company's observation port is larger, and it is also equipped with lidar, infrared and optical observation and sonar systems, which allow the controller to observe the situation on the seabed through these devices even in very low conditions, and can accurately locate and dock the submarine that needs to be rescued.

These equipment condenses the top technology accumulated by Huaxing Group Company in these aspects for many years, and is naturally very advanced.

Time flew by, 1 minute, 5 minutes, 10 minutes......

The people waiting on deck held their breath, their eyes glued to the fluttering cables, anxiously waiting for the news of the life-saving bell docking.

At the same time, the command hall was very quiet, and it seemed that the air was frozen.
