What is the purpose of launching satellite in space?
Satellites are used for many purposes. Among several other applications, they can be used to make star maps and maps of planetary surfaces, and also take pictures of planets they are launched into.
What is the need of satellite launch vehicle?
Launchers or Launch Vehicles are used to carry spacecraft to space. India has two operational launchers: Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). GSLV with indigenous Cryogenic Upper Stage has enabled the launching up to 2 tonne class of communication satellites.
Why is it better to launch a spacecraft from near the equator?
The land at the equator is moving 1670 km per hour, and land halfway to the pole is only moving 1180 km per hour, so launching from the equator makes the spacecraft move almost 500 km/hour faster once it is launched.
What happens to satellite launch vehicle?
Expendable launch vehicles are designed for one-time use, with boosters that usually separate from their payload and disintegrate during atmospheric reentry or on contact with the ground. In contrast, reusable launch vehicle boosters are designed to be recovered intact and launched again.
What does launch vehicle do?
launch vehicle, in spaceflight, a rocket-powered vehicle used to transport a spacecraft beyond Earth’s atmosphere, either into orbit around Earth or to some other destination in outer space.
What is meant by satellite launch vehicles?
It is a vehicles with 4 stages using solid and liquid fuels. The weight of the vehicle decreases after each stage because of consumption of fuel at that stage and detachment of that stage (i.e. the empty tank) from its body.
What is difference between launch vehicle and rocket?
Rockets come in many sizes. Some rockets are more powerful than others. Launch vehicles are rockets that can send people, satellites, spacecraft, or science equipment into space.
What is difference between launch vehicle and space shuttle?
Also in space there is no oxygen, so a space launch vehicle usually carries with itself both fuel and oxidizer and are normally rockets or boosters. An example of space vehicle is a space shuttle which has both the abilities to fly to space and can glide inside the earth atmosphere.
What are the advantages of a rocket?
Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations.
What are the advantages and disadvantages of satellite communication?
Satellite communication has a number of advantages: Advantages : Through satellite transmission, coverage over geographical area is quite large mainly for sparsely populated areas. High bandwidth. Wireless and mobile communication applications can be easily established by satellite communication independent of location.
What are the advantages of SpaceX Starlink satellite?
One of the advantages of SpaceX Starlink Satellite service is that it uses Earth’s low-orbit. Since the Starlink satellites are closer to Earth the communication signals take less time to get to and back from the satellite. This results in lower latency, overcoming the biggest problem with typical satellite communications.
Why do we need to design a satellite?
The design of satellites should be compatible with one or more launch vehicles in order to place the satellite in an orbit. We know that the period of revolution will be more for higher apogee altitude according to Kepler’s second law.
What are the benefits of space exploration?
Space exploration provides us access to new raw materials. When we began to launch satellites into space, it allowed us to find new raw material deposits on our planet that we could access to make life easier here.
