What is the network system of the second-generation satellite communication system

1, G: third-generation wireless cellular telephone communication protocol 4G: fourth-generation wireless cellular telephone communication protocol 2G is represented by wireless communication digitalization, Able to carry out narrowband data communication.

2. Mobile communication systems mainly include cellular system, cluster system, AdHoc network system, satellite communication system, packet wireless network, cordless telephone system, radio paging system, etc.

3. The CORS system is the product of multi-oriented and deep crystallization of high-tech such as satellite positioning technology, computer network technology and digital communication technology.

4. Transmission network: Satellite communication systems usually adopt a star-shaped network topology, and ground stations communicate through satellite relays.The transmission network can be wireless or wired. Wireless transmission can be transmitted through satellite signals, and wired transmission can be transmitted through satellite lines.

Briefly describe the classification of satellite communication systems

1. According to the working orbit, satellite communication systems are generally divided into the following three categories: low-orbit satellite communication system (LEO): 500-2000Km above the ground, transmission The transmission delay and power consumption are relatively small, but the coverage of each star is also relatively small. The typical system is Motorola's iridium system.

2. Satellite communication systems can be classified according to any of its three components. From the perspective of space satellites, it can be divided into stationary satellite (synchronous orbit satellite) communication and mobile satellite (medium and low orbit satellite) communication.

3. According to the application environment, it can be divided into sea, air and ground, so there are: Maritime Satellite Mobile Communication System (MMSS), Aviation Satellite Mobile Communication System (AMSS) and Land Satellite Mobile Communication System (LMSS). According to the satellite orbit adopted by the system, it can be divided into synchronous orbit and asynchronous orbit satellite communication system.

4. In the earth station part, the main common is the satellite communication antenna. According to the different requirements of the use environment, it can be divided into dynamic communication antenna, static communication antenna and portable station antenna.

Satellite communication system includes

ground station: Ground station is another important part of the satellite communication system, which is responsible for communicating with satellites, sending and receiving signals.Signal transmission: Signal transmission is an important part of the satellite communication system, which is responsible for transmitting signals from the ground station to the satellite, and then from the satellite to other ground stations or user equipment.

Transmission network: Satellite communication systems usually adopt a star-shaped network topology, and ground stations communicate through satellite relays. The transmission network can be wireless or wired. Wireless transmission can be transmitted through satellite signals, and wired transmission can be transmitted through satellite lines.

Secondly, according to the purpose and function of use, satellite communication systems can be divided into wide-area coverage communication system, local coverage communication system, navigation positioning system and earth observation system.

The composition of the synchronous satellite communication system includes synchronous satellite, earth station and control center. The composition of synchronous satellites includes satellite days.Line subsystem, control subsystem, satellite transponder, power supply subsystem, tracking telemetry instruction subsystem. Satellite antenna subsystem There are two types of satellite antennas: telemetry command antenna and communication antenna.

What parts does the satellite communication system consist of

1. The satellite communication system includesNext part: Communication satellite: It is the core part of the satellite communication system, which is responsible for sending and receiving signals and forwarding signals to ground stations or user devices. Ground station: ground equipment used to communicate with communication satellites, usually consisting of a control station, a receiving station and a rangefinder station.

2. The satellite communication system usually consists of the following parts: Satellite: As a relay station of the communication system, the satellite receives signals sent by ground stations and forwards them to other ground stations or other satellites. Satellites usually consist of one or more transponders for modulation and demodulation of signals.

3. Ground station: Ground station is another important component of the satellite communication system, which is responsible for communicating with satellites, sending and receiving signals. Signal transmission: Signal transmission is important for satellite communication systems.Components, responsible for transmitting signals from ground stations to satellites, and then from satellites to other ground stations or user devices.

4. The satellite communication system includes all the equipment for communication and communication guarantee.

5. The satellite communication system consists of three parts: satellite terminal, ground terminal and user terminal. The satellite terminal plays the role of a relay station in the air, that is, the electromagnetic waves sent by the ground station are amplified and then sent back to another ground station. The satellite body includes two major subsystems: the star carrier device and the satellite parent body.

6. What parts does the satellite communication system consist of? The satellite communication system consists of a communication satellite and an earth station. Earth stations can only point to a synchronous satellite, and two or more earth stations can establish direct satellite circuits through the same synchronous satellite.
