What is antenna subsystem in satellite communication?
The antenna subsystem are complicated mechanical assemblies that are folded into dense packet for launch and must be deployed in large accurately alight assembly during orbit. Antenna receive the uplink signal and transmit the downlink signal .
What are the types of antenna used in satellite communication?
Four main types of antennas are used on present communication satellites: wire antennas, horn antennas, reflector antennas, and array antennas.
What are the various subsystems in the satellite explain the power system?
Power Systems Power system is a vital subsystem, which provides the power required for working of a satellite. Mainly, the solar cells (or panels) and rechargeable batteries are used in these systems.
What is a satellite subsystem?
Satellites subsystems are used for many purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and space telescopes. Space stations and human spacecraft in orbit are also satellites.
What is subsystem in communication?
The communications subsystem is responsible for ensuring telecommunication between the satellite and another system, which may be either another satellite or a ground station.
What are the elements of a basic satellite subsystem?
Satellite Subsystems in Satellite Communication Systems
- Power Supply System.
- Attitude and Orbit Control System.
- Telemetry, Tracking and Command System.
- Communication Subsystem.
What is communication subsystem?
What are the elements of satellite communication system?
Satellite communication has two main components: the ground segment, which consists of fixed or mobile transmission, reception, and ancillary equipment, and the space segment, which primarily is the satellite itself.
What is a communication subsystem?
What are the subsystems of satellite communication?
Satellite Communication – Subsystems. In satellite communication system, various operations take place. Among which, the main operations are orbit controlling, altitude of satellite, monitoring and controlling of other subsystems. A satellite communication consists of mainly two segments. Those are space segment and earth segment.
How do satellite antennas work?
Those are receiving of signals, which are coming from earth station and transmitting signals to one or more earth stations based on the requirement. In other words, the satellite antennas receive uplink signals and transmit downlink signals. We know that the length of satellite antennas is inversely proportional to the operating frequency.
What are the different types of antenna used in satellite?
Satellite Antennas. The antennas, which are used in satellite are known as satellite antennas. There are mainly four types of Antennas. They are: Wire Antennas. Horn Antennas. Array Antennas. Reflector Antennas. Now, let us discuss about these antennas one by one.
Can the earth station antenna be directed at a satellite?
So, the maximum gain of the earth station antenna can be directed at satellite. We can calculate the look angles of geostationary orbit by using longitude & latitude of earth station and position of satellite orbit.
