"Yes... our navigation signal receiving stations in Australia, Guyana, South Africa and North Africa have not received any signals from orbiting navigation satellites since 2 am GMT..."

The European Space Agency official on the other end of the phone said anxiously. After Drain listened, he immediately raised his arm and looked at the Rolex watch in his hand. At 2 am GMT, 10 hours have passed.

The signal from the "Galileo" navigation test satellite cannot be received for 10 hours. This can already be sentenced to death for spacecraft in the sky in ordinary space operations management.

If it is an ordinary spacecraft, the death penalty is sentenced to death. The European Space Agency is not a small unknown role. This loss is not a big deal, let alone those involved in aerospace know the uncertainty of outer space. The failure rate can never be eradicated. Therefore, in the face of failure, astronauts from all over the world are very calm and just need to find out the problem.

The problem is that the problem now is the "Galileo" navigation test satellite, which wants to seize the priority orbit, and the "Galileo" navigation test satellite with a good frequency band, especially after a big country in the east has launched two domestic navigation satellites. This attribute of the "Galileo" navigation test satellite has become more prominent.

Even if it can't be built, I TM will take the pit first. If you can't kill you, you can do it if I'm sick of it.

But now, the "Galileo" navigation test satellite suddenly hits the street. Even if you have already greeted the International Telecommunication Union, you have to rely on something. No, nothing. Even if the International Telecommunication Union wants to favor you, there is no reason. .

After all, it is an international organization, and the basic face is still needed.

As a result, a cold sweat broke out on Delane's face immediately. If it really hits the street, it is unknown whether Europe can re-emerge with the US$300 billion global market.

So Delaney ignored the presence of the 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, and it is impossible under normal circumstances. Was the signal interruption accident hit by space junk or malicious interference by some malicious organization?"

"Maybe it's not..." The European Space Agency official on the other end of the phone said in a rather frustrated tone.

"What's that?" Delane was a little impatient.

"It is very likely that our navigation communicator has insufficient power, and it was covered by the more powerful communicators of two navigation satellites just launched by a major eastern country..."

"What?" Before the other party could finish speaking, Delane felt dizzy in his head, and immediately a group of nameless anger poured out of his chest, and shouted at the phone: "This is impossible...how much is the carrying capacity of the Long March series of carrier rockets? Don’t I know? Two satellites with one arrow, at best, a load of 2 tons. Excluding the fixed lock and separator, 1.8 tons is good. Divided by 2, each satellite is at best 900 kg. You said it’s less than a ton. How much power can be installed in the satellite platform?

We must know that the total power of our "Galileo" navigation test satellite is only one kilowatt, and two of the atomic clocks are almost 200 watts per minute. This is the limit of our Europe. Has it reached this level? "

Angrily, Delein spoke quickly, and hurled several souls to torture the opponent through the phone like a gun.

The other party was naturally unable to answer, but even so, the European Space Agency official on the other end of the phone said something unbelievable: "I admit that your suspicions are correct, Mr. Delane, but there is one The fact is... but it’s hard to deny, that is... Since the two navigation satellites of a large eastern country successfully entered orbit and started to send navigation signals to the ground, our satellites have lost their signals. All coincidences are too weird. Isn’t that? Is there a problem with the explanation?"

"That's impossible!"

Delane was taken aback for a moment, but the next moment he replied in a more annoyed tone: "Two satellites, even with a kilowatt of equipment, can't dominate the entire space. It's space... the vast space! "

Delane’s emphasis is not unreasonable. Radio waves do have the characteristics of mutual interference. However, due to the vastness of the control, the communication equipment carried by ordinary satellites will interfere with each other, it is temporary. After all, The conditions required for continuous interference in a large area are really not generally harsh.

At the very least, the power must be large, otherwise how to cover the entire large area outside the earth?

Furthermore, it is necessary to divide the layout. After all, the radio waves follow a straight line, but the earth’s orbit is circular. If the atmosphere in outer space provides refraction of radio waves, if you interfere with the earth, it will not affect the earth. Operation.

The ground stations of the ‘Galileo’ navigation test satellites are distributed all over the world. Even if the navigation satellites of a major eastern country are powerful, they cannot cover the entire earth. The ‘Galileo’ navigation test satellites always have the opportunity to send out signals.

It is for this reason that Delane feels that the European Space Agency official on the other end of the phone is nonsense, and feels even more angry. What he wants is the truth, not evasiveness and rejection!

However, the European Space Agency official on the other end of the phone didn't seem to feel Delane’s anger, and he still said hesitantly: "The problem is that a large country in the east is not building two simple navigation satellites this time. UU read www.uukanshu.com and It is a network similar to a constellation. To be honest, if it weren’t for the judgement given by the expert committee through data detection, I...I can’t believe it...they actually came up with such a genius idea, even...the first generation of navigation satellites As a general signal transmission node, it cooperates with the three relay satellites already in orbit to form a satellite local area network capable of covering the whole world.

Although their satellites have different functions, they have a common feature, that is, the communication power is generally too large, and the navigation signal frequencies between us are too close. Their high-power equipment only needs to expand the coverage slightly. The signal can easily be interfered and lead to failure..."

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

Wrong, he is actually covered by a big net. It is hard to imagine a solitary'Galileo' navigation test satellite in space, facing several first-generation navigation satellites, second-generation navigation satellites and relay satellites. What is the feeling of the radio output of the information transmission constellation all the time?

It’s not a human being to lose, otherwise you will definitely scream loudly: "Master, take in the magical powers, the disciple knows it is wrong, and never touch the bones again~~~"
