    Functional camouflage castration of mass-produced radars has no direct benefits for national defense, but it can ensure that the current situation does not become turbulent. The emergence of the Falcon engine has already improved its deterrent effect on neighboring countries.  , but that is only from a power perspective, and has not yet reached an invincible height. According to the design performance of the J-20, even if it is equipped with a Falcon engine, it is impossible to improve its stealth capabilities, let alone improve its ability to target missiles.  defense capabilities, which is acceptable to neighboring countries and Western countries.

    But if Dongchen's phased array radar is released, I'm afraid the whole world will be in chaos. The strike capabilities of the air force around the world will be greatly reduced in front of Dongchen. The most important thing is that Dongchen's own fighter jets will be equipped with this  After building a radar, it will have sufficient pre-emptive capabilities, and all aircraft will be unable to hide in front of it. This is simply a scientific research result that can reverse the entire form of air combat. Once released, it will inevitably receive pressure from all over the world.

    Zhang Wenhao himself is more inclined to the idea proposed by the senior management. Under normal circumstances, even the pilots themselves cannot grasp the essence of a radar with great potential. However, once the critical moment comes, this kind of radar will no longer be able to  Hiding one's own need, just show your true ability and fight to the death with Ya. Even after a fight, no one is still hiding it.

    Based on this idea, Zhang Wenhao asked the waiter to redesign the radar. Therefore, the redesign added a new function. The power of the radar and the ability to perceive radar waves were locked to ensure that under normal use,  There is no obvious difference with ordinary phased array radars, which greatly reduces the exposure probability of this radar.

    Soon, the waiter added a fully functional locking module to the original basis of the radar. The locking module is remotely controlled. Most of the functions of all radars are locked when installed, and the control  The locked terminal will be manufactured separately and provided to the military senior leadership, who will have fundamental control over it. As long as they enter the authorization code and confirm the unlocking, the phased array radars mounted on all fighters will reach the terminal in an instant.  its true detection capabilities.

    The military's order quantity for this kind of sky-defying radar is not high. The total number of fighter-mounted, early-warning aircraft-mounted, ground vehicle-mounted and fixed units is no more than a hundred sets. Zhang Wenhao scheduled the production of radars after satellites.  After Dongchen manufactures his own stereopositioning satellite, he will then manufacture the radar they need for the military.

    More than half a month later, Dongchen's positioning satellites have all been offline. Zhang Wenhao has the ability to launch launches around the world at the same time. In other words, in the first round of launches, Dongchen can launch at least more than ten satellites into the sky, basically building a coverage  A complete navigation system for the Asia-Pacific region. However, in Zhang Wenhao's idea, the first phase of the launch would only involve domestic satellite launch bases launching four satellites for themselves to fully cover the entire country to conduct the first phase of testing.

    The first phase of the launch mission is evenly allocated to the two established satellite launch centers, Xichang and Jiuquan. The two satellite launch centers will each launch two Dongchen positioning satellites within three days, and will be responsible for the launch mission.  It is the Long March 3A, China¡¯s most technologically advanced and most successful tripolar launch vehicle.

    All launches of the Long March 3A carrier rocket from 1994 to the present have been successful without any failure, and the launch range also meets the needs of positioning satellites. Most Beidou positioning satellites are launched into orbit by it, and its various indicators are also  All meet the needs of Dongchen positioning satellites.

    When forty satellites were ready for launch in Jiangcheng, Liu Qiyang, chief engineer of the Jiuquan Satellite Launch Center, went to Jiangcheng to meet with Zhang Wenhao. They expected to launch at least five positioning satellites for Dongchen within a few months in the second half of this year.  It is also the one with the heaviest mission among all Dongchen's launch partners. Moreover, the launch of Dongchen's first satellite was also undertaken by the Jiuquan Satellite Launch Center.

    After Liu Qiyang personally went to Jiangcheng and visited the positioning satellite that Dongchen was preparing to transport to Jiuquan, he was quite surprised and said: "The size and weight of the satellite are 400 kilograms lighter than Beidou, and the volume is also reduced by about 25%, and the surface area of ??the solar cell is also smaller.  It is 30% less than Beidou. Under such circumstances, can the satellite ensure sufficient power to operate?"

    "Of course." Zhang Wenhao said with a smile: "The power conversion efficiency of our solar panels is higher than that of normal panels. In addition, our batteries have a larger power capacity with the same weight and volume, so it is completely  It can meet the operational needs.¡±

    Liu Qiyang nodded and said: "The launch window starts from 8:45 pm three days later and ends at 11 pm seven days later. Our current launch plan is that the first satellite will be launched at 10 am four days later, and the second satellite will be launched at 10 am four days later."  At eight o'clock in the morning six days later, the launch vehicle was ready. According to your request,They just launch, and everything after entering orbit is controlled by Dongchen himself. Therefore, after the satellite arrives in Jiuquan, it can be loaded onto the launch vehicle, and then when the launch time comes, as long as there are no unexpected situations, the satellite will be launched on time.  .  "

    Zhang Wenhao thought for a while and asked: "There are four days in the window period. Can we take advantage of this opportunity to launch another satellite?"

    Liu Qiyang said: "From a hardware perspective, the problem is not big. Our launch vehicles are sufficient. However, the biggest problem is that we have never carried out such an intensive launch mission. Launching two rockets in four days is already a big problem for us."  It¡¯s a big challenge, let alone launching three.¡±

    Zhang Wenhao said: "You don't have to put too much pressure on us. We just need to complete each launch in an orderly manner. As long as the satellite is put into orbit, we will do everything ourselves."

    Liu Qiyang thought for a moment and said: "If we just undertake the launch mission, then I think this is not a big problem. We can now put a Long March 3A rocket into the waiting room within 24 hours."  state."

    Zhang Wenhao nodded and said: "Then prepare according to the frequency of launching three missiles every four days."

    Liu Qiyang reminded: "If this is the launch frequency, insurance companies will not be willing to insure the third satellite."

    "No problem." Zhang Wenhao waved his hand and said: "If eighty can be launched within four days, Dongchen can fully bear half of the loss rate. What we are pursuing is speed, not cost."

    Liu Qiyang nodded helplessly. If it were to undertake a commercial launch under normal circumstances, the launch client would usually struggle with liability and insurance for a long time. Because the launch cost is so huge, once it fails, the insurance company will need to pay compensation for a long time.  For a period of time, moreover, it takes a long time and cost for a general enterprise to entrust the development or order to purchase an artificial satellite. Once it fails, even if the insurance company pays full compensation, their second launch will have to wait a long time before it is ready.  However, Dongchen does not follow this routine. They are not afraid of breaking the satellite. Even if no insurance company is willing to contract, they are not worried. This kind of wealth is far beyond the reach of even state-owned enterprises and central enterprises.

    Due to a temporary change in the launch plan, from the original two satellites in four days to three satellites in four days, Liu Qiyang did not wait for Dongchen's satellite to set off, and took the first flight back to Jiuquan to arrange a new launch mission. The current sanitary launch has been compared to  It has been much faster in the past, and the technology of launch vehicles has matured, especially the Long March 3 series of launch vehicles. Not only is the technology mature, but it also has a high launch frequency. Therefore, the Jiuquan Satellite Launch Base has built its own launch vehicle reserve. In this way, every launch vehicle  For each launch, there is no need to transport the rocket all the way to the launch base by train. Once there is a launch mission, the base can assemble and debug the stocked launch vehicle and add fuel before launch.

    As soon as Liu Qiyang left, Zhang Wenhao arranged for Dongchen's own 747-8 transport plane to go to Jiangcheng. Two 747-8s, one carrying three satellites and the other carrying two, took off one after another that night, flying to Jiuquan and  For the two satellite launch centers in Xichang, the BBJ-2 business jet Zhang Wenhao took flew directly to the Jiuquan launch center.

    When they arrived in Jiuquan, a Long March-3A carrier rocket was already standing on the launch pad. Except for the satellite fairing part, which had not yet been installed, the other three-pole rockets had been installed. Dongchen's plane  As soon as they landed, the staff immediately transported the three satellites to the assembly room and installed the satellites in the fairing.

    A satellite launch, if broken down, has countless important links, but generally speaking, there are only two links, one is the launch stage, and the other is the satellite into orbit.

    Take the Long March 3A launch vehicle as an example. The structure of the three-pole rocket makes each stage an independent working unit. Each stage rocket has its own mission, which is to push the rocket to a fixed height, then disintegrate and then disintegrate.  The next stage of the rocket is ignited until it finally reaches the intended orbital altitude, and then the satellite fairing opens, releasing the satellite.

    When the satellite is successfully released in the predetermined orbit, the launch process is considered to be successfully completed. All that remains is the orbiting and joint adjustment of the satellite. When the satellite reaches the orbit, it must deploy solar panels in the orbit. This is the core energy source for the satellite to work in outer space. If  If the satellite reaches orbit but cannot deploy its solar panels, then the satellite is basically scrapped. If the satellite reaches a predetermined altitude and the solar panels have been deployed and the energy problem is guaranteed, but the ground cannot contact or control it, this is also an extreme situation.  It's a big tragedy. Koreans often make this mistake. Once the satellite is in the sky, they either refuse to stop when it reaches the orbit. They continue to send the satellite to a higher position. After sending it up, they lose contact at every turn. In the end, it is completely equivalent to  Spending a lot of money to send a pile of scrap metal to the sky.

     Dongchen's satellites all use future high-end technologies, and the technology is extremely stable and reliable. For Dongchen, as long as there are no problems with the launch, the success rate is almost 100%.  (To be continued. Please search Piaotian Literature, the novels will be better and updated faster!)
