Coming out of Zhang Shuxian's office, Jiang Xinwei politely declined Wen Guozhong's invitation and went to the Academy of Sciences.

The purpose of his visit here was to ask the Academy of Sciences to send experts to assist him in setting up a satellite ground station and to realize the positioning function for the positioning satellite. Satellite timing is only an incidental function of positioning satellites, and the most important function of positioning satellites is positioning. However, in order for positioning satellites to achieve perfect and accurate positioning, they also need ground stations.

The ground station is not only a satellite in the sky to monitor, nor is it just a command to the satellite in the sky to adjust the attitude, but more importantly, the ground station must give the satellite in the sky an accurate three-dimensional coordinate.

The coordinates of the positioning satellite itself need to be given by others, jokes, right?

Really, as ridiculous as it sounds. Although the positioning satellite has the ability to measure its own altitude, latitude, and longitude, these are not very accurate, after all, the measuring instruments and measuring equipment it carries cannot be very bulky, nor can it be very precise, otherwise the cost is too high and the operating life is too short.

The heavier the satellite, the more energy it consumes to fly in space, and the faster the fuel to maintain orbit is consumed.

Therefore, the satellite's own precise coordinates have to be sent to it on the ground, and they must be corrected at least once a day.

The satellite receives its own coordinates, and then sends it to all the positioning terminals that can receive these coordinates, and also sends accurate timing to these terminals, and the terminals on the ground (including airplanes and ships) receive these two signals and receive more than two positioning satellite signals in order to calculate their own accurate coordinates, which is the precise positioning.

Jiang Xinwei now hopes that the Academy of Sciences can help him build a ground station in Tunia.

The negotiations between the two sides went smoothly because Jiang Xinwei was willing to give money. The Academy of Sciences still lacks experience in positioning, and there is still a big gap with the satellite positioning power (the United States), and of course it hopes to do experiments.

With Jiang Xinwei, the unjust big man, they certainly want to.

As long as he pays for it, let alone build one, they are willing to build ten or a hundred, anyway, this thing is not military equipment, there is no big sensitivity, as long as other countries do not steal our technology.

The next step is to discuss specific issues such as the amount of funds, coordinate accuracy level, and construction date, and Jiang Xinwei naturally arranged for others to do it.

According to Jiang Xinwei's meaning, it is to build a simple ground station now, the sooner the better, solve the problem first, and improve the accuracy after it has it.

When the Academy of Sciences heard that Jiang Xinwei was willing to build it step by step, it was naturally even more happy, and it was not easy to solve the problem or not? They did not have any technical pressure, and they could use the old equipment now, and it would be open in a few days.

You must know that although Huaxia is not a satellite positioning power, but it is also a satellite power, the first satellite was launched in 1970, and there is a technology for positioning satellites on the ground.

After more than 20 years of hard work, Huaxia's satellite positioning technology has been quite mature, and at most it is a little bit behind accurate satellite positioning.

They naturally have this self-confidence.

Seeing that they were happy, Jiang Xinwei didn't feel like being a fool, anyway, what he is asking for now is fast, and the accuracy is low, as long as it can be used, it's a big deal I asked Mayoni to buy more missiles at that time, and use the number to make up for the accuracy.

Yes, Jiang Xinwei is busy helping that ambitious woman. He feared that the French would be annoyed by the loss of a task force and might send a large army to Tunia for a full-scale attack.

Now Mayoni can't buy GPS-guided missiles from the United States, so Jiang Xinwei has no choice but to get a simple positioning system by herself. If France doesn't invade Tunia, forget it, if they do, they have to suffer a little more.

As for the seeker of the missile, it will have to be solved by Mayoni herself, or buy it or develop it herself.

As for buying them from Huaxia, it is impossible! Huaxia itself does not yet have mature satellite-guided cruise missiles. As far as the urine of the Chinese military is concerned, the second generation will definitely not be sold without the development of the second generation.

Besides, now that France and Tunia are at war, it is inconvenient for a responsible power to sell weapons and equipment, right?

The reason why Huaxia approved the sale of the newly developed Steel Dragon 001 tank last time was not because the military changed its principles, but because there were other reasons. There are three reasons: First, this tank was developed by Jiang Xinwei's company, and it was also promised by the superiors that they had the right to import and export. Second, Jiang Xinwei promised him that he would develop a better tank than this tank. Thirdly, the military also hopes that this tank can enter real combat to see how real it will perform. And the military also wants to make some money.

After reaching a preliminary agreement with the Academy of Sciences, Jiang Xinwei said goodbye to them and returned to his communications satellite laboratory. This is Jiang Xinwei recently arranged for Zhang Gang to be established in the capital, and now everything is in the initial stage, scientific researchers are still gathering, and it will take a lot of time to really enter the research and development.

Before she could sit down, Mayoni called: "Honey, how are the positioning satellite negotiations going?"

Jiang Xinxu smiled and said, "It's going well. However, this thing can only be civilian grade for the time being. ”

Mayoni happily said, "Thank you." Civilian grade is not bad. As far as your country is concerned, it will certainly not allow the export of military-grade positioning systems. At least it solves the problem, doesn't it?"

Jiang Xinwei said: "I think so too, let's solve the problem first." And for army marching, fleet sailing or something, the civilian class is enough, just know which direction to go. ”

"It's a pity we don't have a fleet yet," said Mayonie. There were only a few small gunboats, which could not be separated from the coast for several kilometers. ”

Jiang Xinwei smiled: "Take your time." You, this time you are so bold that you have beaten the dignified France so badly. I like it, though. …… By the way, you have to watch out for the revenge of the French, I'm afraid they're going to bomb Banjiasi, don't let them blow up the good Banjiasi to rubble. ”

Because Banghasi was negotiated between Tunia and Kajifi, it was a peaceful handover, and the entire urban area was not affected by the war, and although the citizens of the city were scared enough, there was nothing to lose.

Mayoni said, "I know. We already know the evacuation plan, and we must not allow civilian casualties. Speaking of which, she said the purpose of today's call, "Honey, I want to ask you to do me two favors. ”

Jiang Xinwei asked, "What's busy, why are there two things at once?"
