"At 10:58 this morning, the first maritime satellite of the United Nations, successfully launched the S8 maritime satellite is an important part of the United Nations application in maritime rescue operations, maritime satellite can help maritime calls, this sea rescue action The promotion provides protection ... It is reported that the United Nations will launch three maritime satellites, these three satellites will run in the earth synchronous track, and its work range will contain global ... "

On January 10, 1992, 12 o'clock in noon, the angel smelled channels began reporting on the Wen of the United Nations, the United Nations, the United Nations this morning.

However, for the average person, it is difficult for us to attract their interests. They are probably not found to have the impact on them at this time.

For the average person, they are now paying attention, in fact, the two heavyweight news of the Eden planned and earlier before the previous day.

As for what maritime satellite, for them, it is not very important.

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

Because it was in the first two days, Motorola also announced their plans, and their quarium plans have begun.

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

They are obviously misunderstood - Catherine did not take into account the things about Motorola, for the comet scheme, Catherine did not put it in the heart, in the end of last year, the funds in the comet schemes from the comet When the stock market was gradually smoke, Catherine now is no matter what the plan is not asked.

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

The quarry plan seems to be very powerful, but the number of satellites they use is too much, so maintenance is very difficult and from another perspective, if they cannot use the phone cost and the signal strength of the phone cost and the If the upgrade, then the last is only the same as the same history.

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

Because the history of history does not participate in this plan, they expressed their dismissive for the comarter plan, because this plan is really defective.

If the other party reacted, then adjusted the strategy in time, Catherine may not strand the chicken.

Although the problem itself is a big defect,

However, the comarter plan itself wants to avoid loss or otherwise, when Motorola sells the comarter company, why can the company earned more than 20 million US dollars?

The

......

The United Nations satellite launches also caused a small sensation.

- All, because of a resolution of the United Nations: such a resolution on humanitarian and space safety procedures

This resolution in this history does not exist is the product of the cold war.

This Convention initially stipulates importance and restrictions in the earth synchronous satellite orbit

Earth synchronization track, also known as 24-hour track, the satellite track cycle is equal to the rotation cycle of the earth in the inertia space, that is, 23 hours and 56 minutes and 4 seconds, and the direction is also, the satellite is the same at the same time at the same time at the same time. When the track is coincident with the equatorial plane, it is called the earth stationary orbit, that is, the position of the satellite and the ground remains unchanged.

Earth synchronous track is a circular earth synchronous track for zero angle is called an earth still track because the satellite running on such a track will always be at the empty side of the equator, which is stationary relative to the surface of the earth. About 36,000 meters of the coverage is very wide, using 3 such satellites on the equator of the earth, can achieve global communication outside the Northern Arctic Some parts of the Northern Arctic, now Catherine's three maritime satellite is because of this Principle

According to the resolution, the synchronous track is a very important track of the earth, and the products similar to the communication satellite are not allowed to be transmitted to this track, because this is "human interest community", and the United Nations also temporarily synchronized track The number of satellites has made initial division, and now, the initial 60 satellites, in addition to the 10,000 satellites, the rest of the 50 satellites will be divided and formulated in the United States, but only when it is at this time. Who wants to give yourself a position, so it is still arguing

Earth synchronous track satellite is also called still satellites, radio waves radiated in this satellite, the coverage area of ​​the earth is basically stable, within this coverage area, any earth station can achieve 24 hours uninterrupted communication therefore, Synchronous track stationary satellites are mainly used for land-fixed communications, such as telephone communications, TV programs, but also used for sea mobile communications, but it is not as many base stations like land on the end of cells, only satellites are one The large base station, the mobile service switch center is still located on the shore, that is, the communication between ships and ships between the sea mobile terminal, it is necessary to achieve the satellite two.

For example, if the Boat needs to contact the ship, then the Boat will send the signal to the satellite, and the satellite hop to the mobile business exchange center on the shore station, then, the shore station will send the signal to the satellite, and then satellite Jump to Boat

This is the principle of Catherine's maritime satellite

In theory, the number of satellites that can accommodate the earth synchronous track is quite huge, but due to technical and some inevitable factors, satellites cannot absolutely absolutely relative to the earth, but also deviate from the Earth Synchronous Track, in order to prevent satellite due to crowding production Accidents - Specific sayings may be collisions, because they are not absolutely stationary, in some cases, may also seriously deviate from the original track - so its actual number is greatly reduced.

The United States is to use this reason to file this resolution.

They were originally expected that the Soviet Union would refuse this proposal, they have been prepared to make long-term confrontation with the other side.

But who knows Andropov hits the snake, bit this resolution

This is what the United States did not think of

After the success of the moon, the Soviet Union has already settled three times, and they are self-confident, they are not afraid of the United States in this regard.

Americans did not think that there would be such a thing, so they finally, the two sides on the number of satellites, this time is already entangled.

And other countries, this time, most of them are waiting next to soy sauce, although the country like the British and France is also in the business, but many countries are leisurely watching the two giants in the world. Chatting there. Argument

The reason why the reason is also very simple - the launch of the synchronous track is too difficult, difficult to in addition to the Soviet Union and the United States, basically no country's ability to launch synchronous track satellites, they want to launch themselves The satellite, only the relationship between the United States and the Soviet Union, but some people have calculated, this cost is too great, and the disadvantage is greater than the profit, they can't bear it.

Because the limitations and launch fields are generally not affected on the equator, most carriers cannot be delivered directly to the synchronous track, and must be divided into three stages to enter the first step, carry the rocket to send satellite By the parking orbit of 200300 km from the ground; the second step, the satellite is added to the transfer track and the synchronous track, that is, the distant point of the transfer track; the third step is to ignite the engine. Engers satellites into the Earth synchronization track, and adjust the satellite's gesture with a small engine on the satellite, so that the satellite completely enters the synchronous track

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

In the equator, it is transmitted from West East, reaching the required track height, fixed in place, the problem solves the unfortunately, who knows what the countries located near the Equator ... What is the situation ...

Uncle Black Uncle said that it would be very willing to let these people build a launch site in their own country, but other countries will obviously do not agree ...

Although this first batch of sixty satellites have a bit ridiculous, no matter whether it is the United States or the Soviet Union, this time is a malicious attitude in maintaining this strategy.

The United States wants to strive for our own benefits, eliminating other countries, while the Soviet Union is going to negotiate with this resolution.

To put it, I originally want to veto this agreement, there is a country - China

If Mei Su wants to be space at this time, it is going to say that for themselves, it does not have the greatest threat, but China who cannot launch synchronous track satellites is a bad thing. news

China has also ranked among one of the big rogue, and it is prepared to waive your own veto to give this plan to the full amount.

At this time, the United States and the Soviet Union have been visiting China, and promised to leave a lot of satellites in China, this time the problem is solved.

Specific arrangements have not appeared at this time, but basically already have a consensus.

Five rogues ... The five permanent members will be able to launch 6 synchronous track satellites, while the remaining 20 satellites, followed by other countries to register and distribute

Although it is a bit ridiculous, the rogue will maintain this comic plan for your own interests.

When the opinion is almost consistent, the United Nations's own satellite is already launching into space ...
