Update maritime satellite is an important part of the United Nations in the operation of maritime rescue operations. Maritime satellites can help maritime telephones to communicate. The development of this maritime rescue operation provides new guarantees ... It is reported that the United Nations will launch three maritime satellites.

Three satellites will run on the earth synchronous orbit, and its working scope will include global ... "[.. COM]

On January 10, 19972, at 12 o'clock noon, the Angel News Channel began to report on the news of the Maritime Satellite of the United Nations this morning.

However, for ordinary people, this kind of news seems to be difficult to cause their interest. At this time, they may not find that this news may have the impact on them.

For ordinary people, they are more concerned now. In fact, the news of the two heavyweight news of the Eden plan and earlier Babita project earlier a few days ago.

As for this maritime satellite, for them, it is not very important at all.

But this news is quite eye -catching in the business community.

Because just two days ago, Motorola also announced their plans, and their star plan has begun.

Although the positioning of the two is different, at this time, many people have seen the atmosphere of the two on the satellite phone.

They are obviously misunderstood -Catherine has never considered the matter about Motorola. For the Star Plan, Catherine has not taken care of at all.

When gradually pulled out of the stock market, Catherine now does not care about this plan.

But Catherine's thoughts did not say it, and such thoughts could not be passed on to others.

The Xingxing plan looks really good and powerful, but the number of satellites they use is too much, so maintenance is difficult. From another perspective, if they cannot make the telephone fee and the signal of the Xingxing plan, they cannot

If the intensity is upgraded, it can only end up in the end.

For Catherine, in this plan, the biggest variable is now.

Because there is no participation in this plan in history. Instead, they expressed their disdain for the Xingxing program, because this plan is really too much.

If the other party reacted at this time, and then adjusted the strategy in time, then Catherine might be stealing the chicken without erosion.

Although the problem is a major defect, the Xingxing program itself is still possible to avoid losses. Otherwise, when Motorola sells the company, why can the newly -taken charge of the company earn more than 20 million US dollars.

What is the profit?

The current positioning of the Xingxing plan is similar to history. This is why Catherine relaxes the La Xing plan, but the problem appears on Motorola's allies ...

The United Nations satellite launch. Internationally, it also caused a lot of sensation.

—— All of this is because of a resolution of the United Nations: such a resolution on humanitarian and space security regulations.

The unwanted UN resolution in this history is the product of the New Cold War.

This convention initially stipulates the importance and restriction of the earth's synchronous satellite track.

Earth synchronization track, also known as the 24 -hour track, the track cycle of satellites is equal to the rotation cycle of the earth in the inertial space, that is, 23 hours, 56 minutes and 4 seconds. The direction is also the same.

The same. When the orbit is reunited with the equatorial plane, it is called the earth's static track, that is, the position of the satellite and the ground is relatively unchanged.

Earth synchronous orbit is a rounded earth synchronization orbit with a zero -angle angle called the earth's static track. Because the satellites running on such tracks will always be located above the equator, and it is static relative to the surface of the earth. This kind of track satellite

The ground height is about 36,000 kilometers. Its coverage is very wide. The three such satellites that are all distributed on the earth equator can achieve global communications except a small part of the North and South Pole.

Satellite is because of this principle.

According to the new resolution, synchronous orbit as a very important track for the earth does not allow products like communication satellites to launch on this track, because this is "the community of human interests".

The number of satellites with synchronous orbits is preliminary divided. Now it is stipulated that the original 60 satellites, except the 10 of the 10 satellites reserved by the United Nations themselves.

At that time, both parties wanted to give themselves one more position, so they still argued.

Earth synchronous orbital satellites, also known as static satellites. The radio waves radiated by the antenna on this satellite are basically stable to the earth's coverage area. In this coverage area, it can achieve 24 hours of uninterrupted communication between any earth station. Therefore

Synchronous orbit static satellites are mainly used in land fixed communication, such as telephone communication, TV show broadcast, etc., but it is also used for maritime mobile communications.

A large base station, the mobile business exchange center is still located on the shore. The communication between the sea mobile terminal (that is, between the ship and the ship) needs to be achieved after a satellite jump.

For example, if the A ship needs to contact the B ship, then the A ship sent the signal to the satellite, and the mobile business exchange center on the shore station was jumped through the satellite.

Jump to the B ship.

This is the principle of Catherine's maritime satellite.

Theoretically, the number of satellites that can be accommodated by the earth synchronous orbit is quite huge, but due to technology and some inevitable factors, satellites cannot absolutely relax the earth, and they also deviate from the earth synchronization orbit.

Accidents -Specifically, it may be a collision, because they are not absolutely static, and in some cases, they may be seriously deviated from the original track -so the actual number must be greatly reduced.

The United States also uses this reason to mention this resolution.

They originally expected that the Soviet Union would refuse the proposal, and they even prepared for long -term confrontation with each other.

But who knows that Androbov beats the snake on the pole and bites this resolution at once.

This was not expected by the United States.

After the success of the moon landing, the Soviet Union has been landing three times so far. At this time, they are self -confidence. In this regard, they are no longer afraid of the United States.

The Americans did not expect such a thing, so at the end, the two sides were entangled with the interests of satellites. At this time, it was already entangled.

In other countries, most of the other countries are playing soy sauce to see the lively. Although countries such as Britain and France are also struggling to be reasonable, more countries are leisurely at this time.

Chatting argument.

The reason why this happens is also very simple -the launch of synchronous orbits is really difficult. The difficulty is that there is basically no country except the Soviet Union and the United States.

In terms of satellites, you can only use the relationship between the United States and the Soviet Union. However, some people have calculated it. The price in this launch is too huge, and the disadvantages are greater than the benefits. They can't bear it.

Because due to the limitations of the rocket's loading capacity and the launch site are generally not affected by the equator, most of the launch vehicles cannot send the satellites directly to the synchronous orbit. It must be divided into three stages to track. The first step.

Send to the mooring orbit 200300 kilometers away from the ground; the second step, the satellite accelerates the satellite to the transfer orbit of the transfer orbit at the diversion speed, that is, the remote point of the transfer orbit; the third step, ignite the engine on the distant location, ignite the engine on the distant location

, Make satellites into the earth synchronous orbit, and adjust the attitude of the satellite with small engines on the satellite, so that the satellite enters the synchronous track completely.

If the satellite launch field of a country is built on the equator of the earth, then it seems that the launch of this satellite is much simpler?

Launched from the west to east on the equator to reach the required orbit height. At the appropriate position, the problem is solved. Unfortunately, everyone knows what the situation of those countries near the equator ...

Uncle Hei might be willing to let these people build a launch site in their own country, but other countries obviously do not agree ...

Although the first batch of sixty satellites' strategies are a bit ridiculous, whether it is the United States or the Soviet Union, at this time, they are maintaining this strategy with a malicious attitude.

The United States wants to strive for the greatest interests and excludes other countries outside. At this time, the Soviet Union wants to negotiate this resolution.

Speaking of which, there is a country that originally wanted to veto this agreement -China.

If Meisu wants space at this time, it is not the biggest threat for them, but for China, which cannot launch a synchronous orbit satellite, it is a bad one

information.

China, which has also been one of the gangsters, is ready to wave its own veto to reject the plan to the full amount.

At this time, the United States and the Soviet Union visited China and promised to leave a lot of satellites to China, and the problem was solved at this time.

Although the specific arrangement has not yet appeared at this time, there is basically a consensus.

Five gangsters... Each of the five permanent members of the Security Council will be able to launch 6 geostationary satellites, while the remaining 20 satellites will be adjusted and allocated by other countries.

Although it is a bit ridiculous, the gangsters still maintain this ridiculous plan for their own benefit.

When the opinions were almost unanimous, the United Nations' own satellite had already been launched into space...
