Chapter 1483

"Yes... Our navigation signal receiving stations in Australia, Guyana, South Africa and North Africa have not received any signals about on orbit navigation satellites since 2 a.m. GMT."

The official of the European Space Agency on the other end of the phone said anxiously. After listening, Draine immediately raised his arm and looked at the Rolex watch in his hand. It was 2 a.m. GMT, 10 hours later.

The signal from the Galileo navigation test satellite could not be received in 10 hours, which could have sentenced the spacecraft in the sky to death in ordinary space operation management.

If it is an ordinary spacecraft, the death penalty is the death penalty. The European Space Agency is not an unknown small role. This loss is nothing. What's more, spacefaring people all know that the uncertainty in outer space is great and the failure rate can never be eradicated. Therefore, in the face of failure, spacefaring people all over the world are very calm and find out the problem.

The problem now is that the "Galileo" navigation test satellite is a "Galileo" navigation test satellite that wants to seize the priority orbit and have a good frequency band. Especially after a big country in the East launched two domestic navigation satellites with one arrow and two satellites, this attribute of the "Galileo" navigation test satellite becomes more and more prominent.

Even if it can't be built, I TM will occupy the pit first. I won't kill you. I'll disgust you.

But now, the Galileo navigation test satellite suddenly pours on the street. Even if you have said hello to the International Telecommunication Union, you have to rely on something. It's not. There's nothing. Even if the International Telecommunication Union wants to favor you, there's no reason.

After all, it is an international organization, and its basic face still needs to be.

As a result, a cold sweat immediately appeared on delaine's face. If it really hit the street, it is unknown whether Europe can rise again in the global market of $300 billion.

Therefore, Draine ignored the presence of an outsider, merlinz, and asked urgently, "what is the reason? I have participated in the ground test of the Galileo navigation test satellite. There is no problem. Under normal circumstances, it is impossible to have an accident of signal interruption, the impact of space garbage, or the malicious interference of some malicious organizations?"

"Probably not..." the European Space Agency official at the other end of the phone was quite depressed.

"What's that?" delaine was impatient.

"It is likely that the power of our navigation communicator is not enough and has been covered by the higher power communicator of two navigation satellites just launched by a big country in the East..."

"What?" before the other party finished, delaine felt dizzy in his head. Immediately, an unknown anger burst out of his chest and roared at the phone: "It's impossible... I don't know the carrying capacity of the long march series of launch vehicles. One rocket and two satellites can carry a load of 2 tons at most. It's good to have 1.8 tons except for the fixed lock and separator. Divided by 2, each satellite can only weigh 900 kg at most. You can't say how much power can be installed in a one ton satellite platform?

You should know that the total power of our Galileo navigation test satellite is only 1000 watts, of which almost 200 Watts are divided between two atomic clocks. This is the limit of our Europe. Do you think the rough technology of a big country in the East can reach this level? "

The angry Draine spoke quickly and smashed several souls over the phone.

Naturally, the other party couldn't answer, but even so, the official of the European Space Agency at the other end of the phone finally said something that made delaine incredible: "I admit that your doubts are all right, Mr. delaine, but there is a fact... It is difficult to deny that... Since the two navigation satellites of a big country in the East successfully entered orbit and began to send navigation signals to the ground, our satellites lost their signals. All the coincidence is too strange. Doesn't that mean there is a problem?"

"That's impossible!"

Delaine was a little stunned, but the next moment he replied in a more angry tone: "just two satellites, even with 1000 kW equipment, can't rule the whole space. It's space... Vast space!"

Delaine's emphasis is not unreasonable. Radio waves do have the characteristics of mutual interference, but on the vast Taikong, due to the wide range, even if the communication equipment carried by ordinary satellites form mutual interference, it is also temporary. After all, the conditions required for continuous interference on a large scale are really not generally harsh.

At least the power should be large, otherwise how can it cover a large area outside the earth?

Moreover, it is necessary to divide the layout. After all, radio waves go in a straight line, while the earth's orbit is circular. Whether there is an atmosphere in outer space to provide refraction of radio waves. If you interfere with the earth, it will not affect the operation of the earth.

The ground stations of the "Galileo" navigation test satellite are distributed all over the world. Even if the navigation satellite of a big country in the East is powerful, it is impossible to cover the whole earth. The "Galileo" navigation test satellite will always have the opportunity to send signals.

It is for this reason that delaine feels that the official of the European Space Agency on the other end of the phone is nonsense, and he will feel more angry. What he wants is the truth, not prevarication and throwing the pot!

But the official of the European Space Agency at the other end of the phone didn't seem to feel Draine's anger, and still hesitated: "The problem is that a big country in the East is not building two simple navigation satellites this time, but a network similar to a constellation. To tell the truth, if it was not for the judgment given by the expert committee through data detection, i... I can't believe... They came up with such a talented idea, and unexpectedly... Unexpectedly... They transmitted the first generation navigation satellites as general signals The transmission node, together with three relay satellites already in orbit, forms a satellite LAN sufficient to cover the whole world.

Although their satellites have different functions, they have a common feature, that is, the communication power is generally too large. In addition, the frequency of navigation signals between us is too close. Their high-power equipment only needs to expand the coverage slightly, and our signals are easy to be disturbed and lead to failure... "

Now delaine was completely stupid. He thought he was just facing two navigation satellites that had just entered orbit?

Wrong. In fact, he is covered by a large network. It is difficult to imagine how a lonely Galileo navigation test satellite in space would feel when facing the information transmission constellation composed of several first-generation navigation satellites, second-generation navigation satellites and relay satellites.

Fortunately, I'm not human, otherwise I will yell loudly: "master, take the magic power, I know my mistake, and I won't touch Baigujing again ~ ~"
