How Sputnik is changing our lives

1. How to determine the use of artificial satellites?

The composition of an artificial satellite can be basically divided into two parts: the satellite body and the payload. Payload is the instrument used by the satellite for experiments or services, and the satellite body is the vehicle that maintains the payload operation. The purpose of a satellite depends on the payload it carries.

2. What are the types of artificial satellites?What is it used for?

The advantage of artificial satellites is that they can process a large amount of data at the same time and can be transmitted to any corner of the world, and the use of three satellites can cover all parts of the world, according to the purpose of use, involving satellite TV programs, GPS, etc.

Satellites can be broadly divided into the following categories:

Scientific satellites: satellites sent into space orbit to carry out experiments or tests on atmospheric physics, astrophysics, geophysics, etc., such as Zhonghua Satellite 1, Haber, etc.

Communication satellites: satellites used as telecommunications relay stations, such as Asiasat-1.

Military satellites: satellites used for military photography and reconnaissance.

Meteorological satellites: satellites that ingest cloud maps and related meteorological information.

Resource Satellites: Satellites that capture images of the earth's surface or deep composition for the purpose of exploring the earth's resources.

Interstellar satellites: satellites that can sail to other planets for exploration and photography, generally called planetary probes, such as Vanguard, Mars, Pathfinder, etc.

Hope it helps.

The weather conditions we see on a daily basis are provided by the Fengyun series of satellites.

Provide data on forests, oceans, etc.

To provide communication services (including our televisions).

Because we provide navigation, weather**, communication, etc., it is closely related. The use of building satellites is very extensive, some are equipped with photographic equipment, used to take pictures of the ground, reconnaissance, survey resources, monitor the earth's climate and pollution, etc., some are equipped with astronomical observation equipment, used to carry out astronomical observations, and some are equipped with communication relay equipment, which are used to relay radio, television, data communication, and other communication signals.

The role of artificial satellitesIt is mainly used in space as a radio communication relay station, which plays a great role in modern communications. Communication and broadcasting satellites have brought about many changes in the production and life of human beings, and they have provided us with services such as radio, television, live broadcast and mobile communications, all of which we cannot do without. A working communications and broadcasting satellite receives a radio signal from Earth or a spacecraft and amplifies it.

Frequency conversion and other ways to another site to achieve the transmission of information. There are many advantages of communication and broadcasting satellites, it covers a large area, the communication distance is long, the transmission capacity is large, not limited by the terrain environment, the communication is high, the cost is low, the benefit is high, it is an indispensable helper in human daily life.

1. The "most sociable" communication and broadcasting satellite

A communications and broadcasting satellite is an artificial earth satellite operating in space and used as a relay station for radio communication. It is an important means of communication in modern times, which has greatly changed our production and lifestyle, providing us with services such as radio and television, live television and mobile communication.

2. Navigation satellites that are "the best at finding their way".

Navigation has gradually become an indispensable guiding tool in our daily life, no matter where we want to go, as long as the navigation is in hand, we don't have to worry about getting lost, and it is the navigation satellite that helps us guide the route.

3. Earth observation satellites that are "the best at reconnaissance".

Some people are accustomed to checking the weather forecast before going out in the morning, and they seem to be a little unsure of the weather. Earth observation satellites help everyone to keep track of the weather at any time.

The significance of building an artificial satellite:

The artificial satellite flies in orbit, and for the earth, it stands high and has a large field of view, and it is a veritable "clairvoyant" and "ear to the wind", and it is very advantageous to use it for observation.

According to the different objects of observation and their uses, artificial satellites can be divided into several categories: meteorological satellites, resource satellites, oceanographic satellites, reconnaissance satellites, and so on belong to remote sensing satellites, space exploration satellites and astronomical satellites belong to scientific experiment satellites, as well as communication satellites, technical test satellites, and so on.

Since astronomical satellites are outside the Earth's atmosphere, they are not affected by all kinds of interference and influence from the atmosphere, and they are used to observe distant celestial bodies much more clearly than they can see on the ground. Meteorological satellites are closely related to people's lives, and are mainly used to observe the distribution and movement of the atmosphere and clouds, and to make weather forecasts.

70% of the earth's surface is ocean, and it is also useful to observe information such as islands, fish, pollution, and tides in the ocean through ocean satellites. Resource satellites are mainly used to observe information on forests, deserts, farmland, villages, cities, rivers and other information on land, and can also be used for resource survey, urban planning, disaster prevention and mitigation, etc.

Sputnik. Making life better has become an indispensable technology in modern society. Although a large amount of garbage has been left in space, it is only that the current technology is still limited and it is impossible to collect and clean up space junk.

The main reason is that the cost is too high), but space junk has little effect on humans on the ground.

There are many uses of satellites, such as communications, environment, meteorology, navigation, resources, monitoring, agriculture, geological exploration, etc., and many aspects are closely related to development. Agricultural satellites, combined with meteorological and environmental satellites, can better guide agricultural production; Navigation satellites make ships and others not afraid to deviate from their routes in the vast sea; Resource satellites can assist humans in detecting certain resources in a large area, instead of using manual slow search; Communication satellites allow us to enjoy more efficient and short-latency communication services. The development of satellite technology has played a significant role in promoting modern society.

It can also be used for deep space exploration, so that human beings can better understand the universe.

The ability to launch satellites on their own.

It has also become an aspect of measuring a country's technological strength, and aerospace technology can also be applied in a variety of ways, and the development of down jackets is said to have made use of spacesuits.

The vegetable seasoning packet is said to use the dehydration technology of space food; Certain materials made by space technology are also playing a role in more places. At present, there seem to be a lot of satellites outside the Earth, but in fact there is still a long way to go for human needs, but the various satellites that continue to be launched and scrapped also make the Earth's orbit full of space junk.

But that's just relatively speaking, the earth's outer space is very wide, the satellite orbit from more than 100 kilometers to tens of thousands of kilometers from the ground, such a spherical shell range can accommodate a lot of satellites, the distance between each other is also very far, tens of thousands of space junk is also under monitoring, the impact on the current space activities is small, there is almost no impact on the ground residents, most of the fine space junk in the atmosphere.

Before the fall of large space junk, the space agency will also notify the residents of the possible landing area in advance, so that there will be no major accidents.

The impact of many artificial satellites in space on people: making life better has become an indispensable art in modern times, and satellites have many uses, such as communications, environment, meteorology, navigation, resources, monitoring, agriculture, geological exploration, etc., which have little impact on the inhabitants on the ground.

Artificial satellites have made great contributions to human scientific exploration, satellites also have a service life, and many artificial satellites that have reached the end of their life and are abandoned will remain in the orbit around the earth in space, becoming space junk Junk runs in the original orbit at a very high speed, and will not easily crash, even if it crashes, most of it will burn up due to the friction of the atmosphere, so it will generally not have a particularly big impact on the life of human beings on the earth.

Artificial satellites are mainly used in various fields such as scientific exploration and research, weather forecasting, land resource survey, land use, regional planning, communication, tracking, and navigation. An artificial earth satellite is an unmanned spacecraft that orbits the earth and orbits more than one circle. Abbreviated as Sputnik.

Artificial satellites are the most launched, most versatile, and fastest-growing spacecraft.

Artificial satellites can be divided into three categories according to their use: scientific satellites, technical test satellites, and application satellites. Scientific satellites mainly include space physical exploration satellites and astronomical satellites, which are used to study the upper atmosphere, the earth's radiation belt, the earth's magnetosphere, solar radiation, etc.

Technical test satellites are satellites that conduct new technology tests or conduct tests for application satellites. Application satellites are satellites that serve mankind directly, and there are the largest types of satellites, including communication satellites, meteorological satellites, reconnaissance satellites, and navigation satellites.

Meteorological satellites

Meteorological satellites use various meteorological remote sensors to receive and measure visible radiation, infrared radiation, and microwave radiation information from the earth, ocean, and atmosphere, and then convert them into electrical signals and transmit them to ground receiving stations. Based on the information collected, meteorologists process it to obtain data on meteorological elements such as global atmospheric temperature, humidity, and wind.

Global meteorological data is available in a matter of hours to make long-term weather forecasts, determine the location and changes of typhoon centres, and forecast typhoons and other storms. Meteorological satellites play a great role in ensuring the safety of navigation and aviation, as well as in ensuring the production of agriculture, fisheries, and animal husbandry.

The application of meteorological satellites in military activities has also been increasingly strengthened, and some countries have established a global system for collecting military meteorological data to provide military units with real-time or non-real-time meteorological data. With the further development of aerospace technology, meteorological remote sensors will develop in the direction of diversification and high precision, which will greatly enrich the content of meteorological forecasts and improve the accuracy of forecasts.

1. Disaster prevention and relief, through the global satellite positioning system to locate the longitude and latitude of the disaster area, so as to facilitate the disaster relief personnel to accurately reach the disaster area. Satellite images are then used to help people understand how the weather will change in the next 72 hours.

2. Satellite navigation, the mobile phone client links the global satellite positioning system through real-time data to understand the geographical location of people, and then plan and navigate the route between the location and the destination.

3. Control the weather, during the Yintan Asian Games and the Olympic Games, the weather and rainfall in the area where the opening ceremony of the Games is held are controlled by launching artificial satellites, and the water content of Tongfeng Wutong is controlled, so that the rain will fall before or after the event.
