Chapter 063 The difference between the two orbits

When it runs out of fuel, it becomes impossible to maintain its previous orbital position, and the satellite's service life ends.

Generally, when a satellite runs out of propellant, its transponders and other systems on the satellite can still function normally.

Some satellites can continue to operate in inclined orbits (with their subsatellite points drawn with an "8" pattern centered on the equator) if the North-South position hold control is stopped.

Alternatively, the satellite orbit can be raised to a "grave" orbit and disposed of.

......

In fact, the geosynchronous orbit and the geostationary orbit are not the same thing, and there are similarities and differences between them.

Geosynchronous orbit and geostationary orbit are both artificial earth satellite orbits with the same running period (23 hours, 56 minutes and 04 seconds).

There are three differences between the two tracks:

First, the orbital inclination is different.

A geostationary orbit is a circular geosynchronous orbit with an orbital inclination (the angle between the orbital plane and the equatorial plane) of zero. That is, the geostationary orbit must be on the equatorial plane; and the geosynchronous orbit plane can form a non-zero angle with the equatorial plane.

Second, observers see different phenomena.

Satellites in geosynchronous orbit pass the same place in the sky at the same time each day, and to an observer on the ground, the satellites appear in the same direction at the same time each day.

The satellite may be in motion relative to the observer for a continuous period of time.

While the satellites running in the geostationary orbit are in the sky over the same place at any time every day, the ground observer sees that the satellites are always in a certain position and remain stationary.

Third, the trajectories of the sub-satellite points are different.

The projection point of the artificial earth satellite on the ground (or the intersection of the line connecting the satellite and the center of the earth with the ground) is called the sub-satellite point.

The motion of the satellite and the rotation of the earth make the sub-satellite point move on the earth, forming the sub-satellite point trajectory.

The sub-satellite point trajectory of a geostationary satellite is a closed curve in a figure-8 shape, while the sub-satellite point trajectory of a geostationary satellite is a point.

Geostationary Orbit Environment Geosynosorbite The space environment of the geostationary orbit region.

The geostationary orbit is a high density area of ​​communication satellites, which is located in the near equatorial area about 6.6 earth radii from the center of the earth.

The space environment of this region is mainly composed of high-energy particles other than gravitational field, thermal plasma, plasma layer plasma, ring current, magnetic field, solar electromagnetic radiation, meteoroids and space debris.

The geostationary orbit area is the area where the earth's space environment is seriously affected by solar activity. When the strong solar wind arrives, the magnetosphere is compressed, and the geostationary orbit area is completely exposed to solar cosmic rays and high-speed solar wind.

During magnetic storms or substorms, high-temperature plasma injected from the magnetic tail can also reach this region, making this region a high-incidence region for spacecraft anomalies caused by the space environment, where high-energy particles (including solar proton events) are injected into the environment and substorms The thermal plasma environment is the most important contributing anomaly and is the region with the most severe charging problems for spacecraft.

This is why, when Zhou Wenwen did it, he felt a headache.

Although it is said that Zhou Wenwen, who protects himself with divine power, should not be afraid of these things at all, but the communication satellite in his hand is not so hard at all, and it is very easy to destroy.

A communication satellite is a satellite that acts as a radio communication relay station.

It is like an international messenger, collecting various "letters" from the ground, and then "delivering" them to users in another place.

Because it "stands" at an altitude of 36,000 kilometers, its "delivery" coverage is particularly large, and one satellite can be responsible for 1/3 of the earth's surface communication.

If three communication satellites are placed evenly in the geostationary orbit, global communication can be achieved except for the north and south poles.

When the satellite receives a weak radio signal from one ground station, it will automatically turn it into a high-power signal, and then send it to another ground station, or transmit it to another communication satellite, and then send it to another on Earth. On one side of the ground station, so that signals from far away can be received.

Communication satellites generally use geostationary orbits, which are located 35,786 kilometers above the Earth's equator.

In this orbit, the satellite revolves around the earth from west to east at a speed of 3075 meters per second, and the time around the earth is 23 hours, 56 minutes and 4 seconds, which is exactly the same as the time for the earth to rotate once.

Therefore, from the ground, the satellite image hangs in the sky and does not move, which makes the work of the ground receiving station much more convenient.

The antenna of the receiving station can be fixedly aligned with the satellite and communicate continuously day and night, without having to "sway" around like tracking those satellites that are not moving, so that the communication time is intermittent.

Communication satellites have undertaken all intercontinental communication services and television transmission.

Communication satellite is one of the earliest and most widely used satellites in the world, and many countries have launched communication satellites.

On April 6, 1965, the United States successfully launched the world's first practical geostationary communications satellite: Intelsat 1.

So far, this type of satellite has developed to the eighth generation, and each generation has certain improvements in volume, weight, technology, communication capability, and satellite life.

The communication satellites of the former Soviet Union were named "Blitzkrieg", including Lightning 1, 2, 3 and so on.

Due to the vast territory of the former Soviet Union, most of the "Bliksem" satellites are not in the geostationary orbit~www.wuxiamtl.com~, but in an elliptical orbit with a large eccentricity.

The first domestic geostationary communication satellite was launched on April 8, 1984, named "Dongfanghong-2", and six satellites have been successfully launched so far.

These satellites have successively undertaken radio, television signal transmission, telecommunication and other work, and played a huge role in the construction of the national economy.

Having said that, after Zhou Wenwen put a lot of effort into putting away the 6 communication satellites and base stations, he killed them and didn’t bother to get them. The follow-up maintenance didn’t go there except once when he sent the Guardian platform to the sky. No matter what, it's all up to the Palace of Doomsday.

So, what is the Guardian platform?

The structure of this platform is the same as that of the Star Palace. It is a mobile platform used by the knights of the Doomsday Palace when they are fighting externally. If the battle is unfavorable, the knights on the mobile platform can "fall from the sky" to support the battle against the ground.

But this thing is useless to Zhou Wenwen, what he needs is a strong thug!

Zhou Wenwen used a little energy and a lot of metal resources to repair this thing, full of expectations that it would be a powerful thing, but when he got this result, he was naturally furious.

The furious Zhou Wenwen planned to destroy this useless thing in person. In order to save the former men, the Palace of Doom quickly woke up the guardian platform, but found the treasure on the guardian platform.
