What is the role of satellites? 20. What is the role of satellites?

Satellites are not all synchronized. Artificial satellites are not all on the latitude plane. There are also warp planes.

According to the orbit, it is divided into low-orbit satellites, medium-high orbit satellites, geosynchronous satellites, geostationary satellites, sun-synchronous satellites, large elliptical orbit satellites and polar-orbit satellites. The polar-orbiting satellites are in the meridian plane. People are more likely to classify satellites by purpose

Military Satellites: Military Uses Earth Resources Satellites: Surveying and monitoring of Earth resources, etc.

Communication satellites: communication, radio, television, etc. Meteorological satellites:

Meteorological Observation and Forecasting Near-Earth Space Research Satellites: Physical Exploration of the Earth and Observation and Research in Near-Earth Space. Geodesic satellites:

It is used for earth shape measurement, geographic coordinate measurement, earth gravity field distribution measurement, and crustal movement measurement. Navigation satellites: navigation of aircraft, ships, etc.

Astronomical Observation Satellites: Peel open the atmosphere and observe the universe directly.

A communications satellite is simply a transit station. Put the signal of the ground station ** another or another ground station. In the ** project, it will involve the amplification of the signal and the conversion of the frequency.

Meteorological and military reconnaissance satellites themselves are similar to radars and can transmit on their own and then receive the signals reflected back.

Different satellites have different roles, including civil, commercial, military, etc.

1. Artificial earth satellites operate in their respective orbits, but their functions and uses are different, and they can be roughly divided into five categories: communications, meteorology, resources, reconnaissance, and navigation.

2. Communication satellites. Its function is to transmit TV and ** signals for people. Without it, it's hard to play across the ocean ** or ** world news, international competitions.

3. Meteorological satellites. It carries remote sensing equipment that looks down on the entire Earth's atmosphere and monitors winds, clouds, rain and forest fires on Earth. The images and data recovered by meteorological satellites are the basis for meteorological scientists and technicians to accurately forecast the global weather.

4. Earth Resources Satellite. It uses remote sensing instruments to discover geographical features that are difficult to find on the ground and at low altitudes, and uses the information it obtains to accurately estimate the vegetation, geology, hydrology, seawater and other resources in various regions of the earth.

5. Reconnaissance satellites. It is equipped with high-resolution cameras and video cameras to photograph ground targets, which can accurately reflect the movement and build-up of ground forces and the changes in various military installations.

6. Navigation satellites. Helping ships at sea to find their direction and position. Through the observation and ranging of more than two satellites, the ship knows exactly the coordinates of its geographical location.

Satellites have many functions, such as: positioning, weather monitoring, military monitoring, etc.

A satellite can be divided into Earth satellites or satellites of other planets according to the galaxy around which it orbits. According to **, earth satellites can be divided into natural satellites and artificial earth satellites.

When it comes to roles, natural satellites are naturally formed in the universe, and it's hard to say what they do. Of course, the moon is a natural satellite of the earth, it can illuminate earthlings, it can also be used to observe time, etc., and you can imagine many beautiful legends. Artificial satellites are widely used, some are equipped with photographic equipment, which are used to take pictures of the ground, reconnoitre, survey resources, monitor the earth's climate and pollution, etc.; Some are equipped with astronomical observation equipment for astronomical observations; Some are equipped with communication relay equipment, which are used to relay radio, television, data communication, ** and other communication signals; Some are equipped with scientific research equipment, which can be used for scientific research and special production under the condition of no gravity in space.

In short, artificial satellites have different uses depending on the purpose of development, production, and use.

Satellites can be used for a variety of purposes, with the following key points to name some of the main application areas:

Weather forecasting: Meteorological satellites can obtain atmospheric and oceanic information on the Earth's surface, leading to weather changes and natural disasters.

Earth observation: Satellites can provide high-resolution maps and images, and monitor the Earth's natural and human activities, among other things.

Navigation: The Global Positioning System (GPS) is a navigation system composed of a network of satellites that can provide accurate location information.

Military: Military satellites can be used for tasks such as surveillance, reconnaissance, and communications.

Scientific research: Satellites can be used in scientific research fields such as space exploration, planetary exploration, and cosmic ray detection.

Commercial: Satellites are also widely used in commercial fields, such as satellite television, internet services, remote sensing, etc.

In short, satellites play an important role in modern society and make great contributions to driving scientific and technological progress and improving human life.
