A single phased array antenna began to be mass-produced after a series of tests in the later stage, and Xiao Er also developed the phased array radar into three different models according to the different needs of different aircraft and ground radars, the new phased array radar is codenamed "Hawkeye", the fighter airborne model is Hawkeye-1, the large aircraft, early warning aircraft airborne model is Hawkeye-2, and the ground model is Hawkeye-3.

Three different Hawkeye radars, the biggest difference is the difference in volume, for a single combat unit such as a fighter, the radar detection distance of three to five hundred kilometers is enough for actual combat use, after all, their own strike ability can not even exceed this distance, and, the larger the distance, the larger the airspace that the radar needs to scan, in this way, the radar first needs more phased array antennas, greater power to meet the detection of longer distances, so that the greater the detection distance, the greater its weight and volume, The more power is needed, and every kilogram of lift-off weight is very valuable for a fighter, so high-power radar is not suitable for fighter jets.

The effective detection range of Hawkeye-2 is within the range of 700-1000 kilometers, and the improvement of the detection range has made the weight of the whole set of radars increase geometrically, but for large aircraft such as early warning aircraft, which mainly focus on radar services, this weight is nothing to it, and Hawkeye-2 because of its larger coverage area, it also greatly increases its demand for processing power, so that Xiao Er has set up a processing platform for it, which is Dongchen's own CPU.

The effective detection range of the Hawkeye-3 is even several times larger than that of the Hawkeye-2, and its core task is only one point, that is, to scan the largest range possible and track as many targets as possible. This radar. It already belongs to the base station-type early warning radar. It has a strong control over the entire airspace, and as a source of early warning information, it can serve a lot of objects, not only can indicate a longer range of targets for air fighters, but also can be combined with the fire control system to directly provide radar services for surface-to-air missiles.

For Zhang Wenhao, the main use of the new phased array radar is to exchange for admission tickets for satellite launches. When he handed over the three radars to the military for testing, Zhang Wenhao discussed with Xiao Er the research and development of stereotaxic satellites, more than 30 satellites, Zhang Wenhao hopes to be able to launch all within a year, and even, a year is a bit too long.

Xiao Er knew that Zhang Wenhao couldn't wait for the stereoscopic satellite positioning system, so at the moment of research and development, he said to Zhang Wenhao: "Boss, I think you can already negotiate with those countries that have the ability to launch satellites." Let them provide us with commercial launch services, if we can use all the launch vehicles and launch centers in the world. Then I think in two months at most, our stereo navigation system can be built. ”

Zhang Wenhao said: "I have consulted the high-level about the overseas commissioned launch before, and the high-level has not raised any objections, but they still hope to complete the launch locally as much as possible. ”

"It's too long." Xiao Er couldn't help but say: "If we rely on domestic launches, it will take at least two or three years to launch all the satellites we need, even if Dongchen now funds and the state to jointly build a new launch base, we do not have carrier rocket technology, we still have to follow the domestic launch capacity, and it is already very remarkable to have ten satellites a year." ”

Zhang Wenhao nodded and said: "This can be communicated with the United States, Russia and those countries in Europe, judging from our current situation, I believe these countries will not refuse." ”

Xiao Er reminded: "Don't forget that there is also Japan, their satellite launch technology is also world-class, but we can communicate with the Japanese government and let Japan also undertake certain launch tasks." ”

Zhang Wenhao thought for a while and said: "You look at the current density of satellite launches in various countries, as well as their maximum launch capacity, estimate how much of the remaining launch capacity is there every month?" ”

Xiao Er immediately searched for relevant information on the Internet, including information that everyone can see on the Internet, as well as confidential information of various countries, and finally came to the conclusion: "Boss, the current satellite launch market in the world is very flat, and there are no large-scale launch missions and plans this year. ”

Speaking, Xiao Er said: "There is also a certain risk in satellite launches, so I estimate that our most conservative ones will have to launch 35 times to ensure that our entire positioning system can cover the whole world, of course, there is also the risk that launch mistakes will bring us risks." ”

Zhang Wenhao thought for a moment and said, "How long will it take to build 35 satellites?" ”

Xiao Er replied: "Soon, we will produce the main body of the satellite by ourselves, and we can also use our own technology for the battery, as for the solar cell, we don't need to develop it ourselves, we can purchase it directly from the supplier." ”

Zhang Wenhao asked again: "How many years is the lifespan of each satellite?" ”

"More than fifty years." Xiao Er replied: "Our technology is absolutely the world's top level, as long as the launch vehicle can send the satellite into the predetermined orbit, at least fifty years, the satellite will not have any problems, if you are really not at ease, you can also launch a few more satellites as a backup." ”

"Counting the backup, counting the possible launch mistakes, at least forty satellites must be prepared, and these will be left to you to complete, as for the launch carrier, I will meet with Director Liu again, and let him tell the senior management, Dongchen can't wait too long, once the satellite is manufactured, we will find the most launch vehicle resources in the shortest possible time for us to quickly complete the launch."

Xiao Er blurted out: "Don't worry, boss, forty satellites are only, it's not a problem, and it won't exceed a two-month cycle, you'd better determine the launch resources of forty satellites within two months, and when the time comes, the satellites can directly enter the launch process." ”

Zhang Wenhao shook his head and said, "I started to do this after I met with Secretary Liu, and I can't wait until you build all forty satellites before launching." Instead, we should seize the time to secure the launch resources. Then whenever you have satellites offline. We're all getting it into orbit the first time! ”

Officer Liu has been very busy recently, after the military got the "Falcon" engine from Zhang Wenhao's hand, the frequent test flights have made the entire high-level pay great attention, and he has become a forward commissioner, most of the time at the test flight site, to convey more first-hand information about the test flight to the senior leaders, and play a certain coordinating role in the entire test flight.

The "Falcon" engine has not really completed the test of multiple models, and Zhang Wenhao's Hawkeye radar has been delivered to the military for testing. At this time, the military is even more busy, a large number of radar, electronic equipment experts poured into the J-20 test flight site, the test flight aircraft radar was removed, replaced with Dongchen's Hawkeye radar, the significance of this test, is not smaller than the engine, if this radar really meets the standards Zhang Wenhao said, then this radar even if it is installed on the J-10, can also bring a lot of improvement to the actual combat capability of the aircraft.

I heard the news that Zhang Wenhao was going to meet with him. Director Liu hurried to Jiangcheng, and the senior management had explained to him before coming. This time to meet Zhang Wenhao, the time should be controlled as early as possible within 48 hours, and after 48 hours, Director Liu will rush back to the test airfield to track the whole process of the J-20 equipped with new engines and new radars.

When Director Liu and Zhang Wenhao met, the two exchanged a few words, and Director Liu said: "Wenhao, now is an extraordinary period, the top management attaches great importance to the two sets of tests of the military, usually I don't even have a pee time every day, this time you called me over, the top management only gave me 48 hours, within 48 hours, I have to return to the scene, so there is no need for the two of us to be polite, you can just say anything directly, When I'm done lately, I'll catch up with you, brother. ”

Zhang Wenhao smiled: "Okay, since you said so, brother, then I won't go around in circles." Saying that, Zhang Wenhao said: "I'm looking for my brother to come over, mainly hoping that you can help me convey a situation to the high-level." ”

"What's the situation?" Officer Liu asked.

Zhang Wenhao said: "We have now started the manufacture of stereo navigation satellites, but the domestic launch capacity is really limited, and Dongchen cannot wait in line for two or three years to launch, so I want to take advantage of the cooperative relationship between Dongchen and international countries to entrust capable countries around the world to provide commercial launch services for Dongchen. ”

Director Liu thought for a while and said: "The high-level is not opposed to this matter, but has certain scruples, worrying that your technology will be exposed to foreign countries, but Dongchen's strength is at present, and no one has the ability to copy it, so I don't think the high-level should have any opinions." ”

Zhang Wenhao said with a smile: "You better confirm with the high-level, if it is confirmed, I will immediately start to promote this matter, and strive to get all the launch needs before our first satellite goes offline, so that as long as a satellite is built, it can be sent to all parts of the world for launch at any time." ”

Director Liu thought for a moment, and then said: "Then let's do it, I'll contact Yanjing now, and convey your thoughts to Yanjing." ”

Zhang Wenhao nodded and said, "The sooner the better." ”

Director Liu smiled: "You still can't trust me? When will I drag you back. ”

Although the information has been transmitted to Yanjing, it has been reported layer by layer, and after the senior management learns about it, it still needs to be discussed through internal meetings, so Zhang Wenhao waited for a full 24 hours, and after 24 hours, Director Liu's mobile phone received an email, the content of the email was very simple: "Regarding matters related to satellite launch, Dongchen is in charge of everything." ”

At this time, Zhang Wenhao was completely relieved, and the high-level let himself be in charge, which means that no matter what you do, whatever you do.

After obtaining this permission, Zhang Wenhao immediately contacted the United States, Russia, Ukraine, ESA, Japan, India, Australia and other countries in the name of Dongchen, and put forward a request from Dongchen to assist in the commercial launch.

When submitting launch requests to these countries, Zhang Wenhao directly pointed out the purpose of Dongchen's satellite launch -- positioning satellites.

This makes those countries that have the ability to launch artificial satellites puzzled, China's Beidou navigation system has been built for the most part, in a few years, perhaps the global navigation system can be completed, and the technical level of Beidou navigation itself belongs to the world's top ranks, after all, the United States GPS is several years earlier than Beidou, and the upgrade of satellites is very difficult, once the architecture of Beidou global navigation is dug up, its comprehensive strength, is engaged in GPS, so, in this case, Dongchen even has to engage in its own positioning system, This is somewhat unnecessary.

After all, no country has yet established two satellite navigation systems by itself, which not only has a huge waste of resources, but also the satellite launch and navigation system architecture itself is also a very costly project, in their eyes, Dongchen does not need to do this, but Dongchen insists on building its own satellite navigation system, and changes the previous wording, no longer to ask for assistance in launching, but to ask for assistance in launching, this time, it can be seen how strong Dongchen's insistence on this matter is, And these countries are not ready to go against Dongchen, anyway, commercial launch itself is not a violation of principle, since Dongchen wants to launch, and there is enough financial support, these countries do not have any need to refuse.

Dongchen has a strong influence in the world, when it announced that it would establish its own satellite navigation system, the world was not surprised by it, but there was not too much discussion, after all, Dongchen's strength is too strong, they have enough financial resources to establish their own satellite navigation system, and they don't know at all, Zhang Wenhao is going to launch the navigation satellite this time, what is the difference between the previous navigation satellite.

The United States replied that it could arrange the launch of eight satellites for Dongchen in a short period of time, and ESA was also very good, and also gave Dongchen the launch capacity of eight satellites, Russia gave five, Ukraine gave two, Japan gave five, and India also gave five.

Even if there is a certain probability of failure, but normally speaking, the launch of 35 satellites cannot reach the maximum number of failures, not to mention, China can provide at least five to eight satellites with the launch capacity, so that the launch needs have been fully solved.
