The refining of communication satellites is not easy, it is necessary to refine the exclusive yin and yang energy collectors, and also refine the components of the signal transmission device, and then place them one by one. After the satellite is initially refined, it will also be deployed and tested, and each finished satellite will take Su Yaowen three days to refine.

The problem with the energy harvester is not a big problem, after all, after refining so many physical objects, there is still a lot of experience. Moreover, because this is only an exclusive version for communication satellites, in addition to being used for flight and maintaining the same speed as the planet's rotation, there is no additional consumption in normal times. Xiaomi has only designed a smaller energy harvester, which is much less difficult to refine.

The real trouble is the device used to transmit signals, the communication satellite is at an altitude of 50,000 kilometers above the ground, which is more than 100 times more than the coverage of the previous signal device, and even the second-generation signal device can only guarantee signal transmission within the range of 500 kilometers.

In order to realize the global common network, the transmission power of communication satellites must be increased by tens of thousands of times that of the present, and if it were not for Su Yaowen's cultivation that had broken through to the Dan period, he might not be able to refine this enhanced version of the signal device.

If you want to achieve global networking, you need to upgrade the signal reception and transmission of communication satellites, so that it can adapt to the current mobile phone.

If Su Yaowen was on the earth, he might need to use a lot of high-tech tools to help him, but in the cultivation realm, it was different, the refining technology and formation knowledge he had here were not inferior to the technology on the earth, and with millet here, it was very easy to integrate their respective advantages.

Xiaomi has made a more thorough upgrade of the previous signal transmission formation. More complex formation sigils have been added to it, and the newly developed formation layout technology has been applied, so that it can receive all signals within 500,000 kilometers, and it can also ensure that the network latency will not be higher than 0 even during busy hours. 1 second. This kind of improvement is enough for the network at this stage.

In order to make the whole planet within the coverage range of signal satellites, Su Yaowen has refined a total of more than 30 satellites, these satellites have the function of sharing resources, if there is a busy period, the satellites will bridge with each other, so that the signal can be transmitted through neighboring satellites, which greatly reduces the working pressure of a single signal satellite.

Because it is used to transmit signals inside the planet. Therefore, the flight orbit of these satellites is also regulated, just like the communication satellites above the earth, which generally choose the geostationary orbit. Because the satellite orbits on this line, the speed of the rotation of the planet is the same as the rotation speed of the planet, which ensures that the satellite will not leave the current operating area because it is too fast or too slow.

Geostationary orbit generally refers to a circular orbit above the equator, and as long as the communication satellite is on this line, it will form a relatively stationary state with the ground. will always be in the same position outside the Earth. The orbital eccentricity and orbital inclination are both zero, and the period of motion is the same as the rotation period of the Earth. If viewed from the ground, the satellite appears to be stationary.

Because the planet where Su Yaowen is located is different from the earth, the surface area is more than three times larger, the volume is definitely not the same, and the rotation speed has also increased a lot, and the position and height of the planet's diameter orbit are somewhat different. These require detailed calculations by Xiaomi to be able to arrive at accurate values.

According to Xiaomi's calculations, on the line of geostationary orbit, as long as ten communication satellites are placed, it can be guaranteed. In the whole planet, except for remote locations such as the poles, the signal transmission in other places can be kept unobstructed. As for the signal problem at the north and south poles, Su Yaowen will place other communication satellites in polar orbit, which can also be used to bridge signals with other communication satellites, so as to ensure global networking. As long as you are not in some area with a disturbed magnetic field, you can use your mobile phone to connect to the Internet.

Although the role of these communication satellites is significant, the manufacturing cost is not expensive, and the materials are only used some ordinary metal minerals, and the real core is still the refining techniques and signal formations inside. These don't need to cost another spirit stone, as long as Su Yaowen consumes a little spiritual energy when refining, in this way, each satellite actually only needs to spend the cost price of a top-grade spirit stone, and there is no problem at all if you want to mass produce it.

Since there is no need to worry about manufacturing costs, in addition to placing a sufficient number of satellites in polar orbit and geostationary orbit, Su Yaowen also plans to place some communication satellites in the high elliptical orbit between the two, so as to ensure that nothing goes wrong. Even if a satellite is damaged or falls for some reason, it will not cause the signal connection in its working area to be lost, and other communication satellites can quickly replace it.

Because of Su Yaowen's cultivation problems, it is not possible to refine powerful long-range weapons and place them on satellites for the time being, but it is still possible to place a camera. It was a billion-pixel camera, the camera with the highest pixel that Su Yaowen could refine at this stage. Although it is not possible to photograph people or objects on the ground very clearly, it is enough to monitor the movement inside the planet.

In the final analysis, it is still because of the low cultivation, and this topic has been mentioned several times by Xiaomi. Su Yaowen couldn't cry or laugh. I've only been cultivating for more than ten years, and it's already great to be able to have this cultivation now, so don't keep mentioning the matter of cultivation all the time.

It took more than three months for Su Yaowen to refine more than 30 communication satellites in one go, and this time it was a big deal. In addition to the more than a dozen communication satellites that follow the rotation of the planet, the rest are spare satellites, which are mainly responsible for secretly photographing the ground in normal times, and can also replace damaged communication satellites in an emergency.

Xiaomi has installed an operating system in each communication satellite, which can control the satellite from a distance, in addition to being used to shoot ground scenes, it also has the ability to control its movement. Because there is an energy harvester inside the satellite, there is endless energy around it, so Xiaomi has added a thruster device that can allow the satellite to move quickly in the universe.

At that time, Su Yaowen wants to know the latest situation somewhere in the Xianluo Continent, so he can let the signal satellite move to that location, take pictures of the ground, and then feed back to Xiaomi. And after a satellite is damaged, these spare communication satellites can be moved to the corresponding position with the help of thrusters to take over their work.

After finally refining all the satellites, Su Yaowen breathed a sigh of relief, refining satellites is not simple. Because the signal formation has undergone an important upgrade, the formation inside is very complicated, and there is only a small gap between the runes and the runes. If you don't notice it for a while and draw a certain formation rune seal wrongly, the entire formation will be scrapped and you need to start all over again, so Su Yaowen's mind must be highly concentrated, and there will be a lot of consumption on his spirit.

After the preparations were over, Su Yaowen rested for a few days before officially starting the journey of the universe. (To be continued.) )
