Artificial satellites are these put into orbit by man. Equipment on a satellite tv for pc is hardened to survive in the radiation and vacuum of area. Since there is not a air in space and therefore no air resistance, satellites are out there in many shapes and sizes. Types of Satellites and their Uses We use satellites for various purposes and all satellites can be positioned in one of many following categories: Communications Satellites Distribution of television and audio alerts, and telephone connections by way of satellite are carried out by Communications Satellites.

These types of communications sometimes need a satellite in geostationary orbit. Today geostationary satellites are used to provide voice, audio and video communications like DTH TV. Navigation Satellites These satellites are of enormous assist to transportation firms, especially transportation over water and thru the air. The US GPS satellites are in Low Earth Orbit (LEO) and may decide place with a precision of 1 cm (0. four inch). However, that very exact positioning is available for military functions only.
Observing the earth is the task for weather satellites, and then especially what occurs within the environment. Different sorts of cameras, like infrared and regular cameras are used to look at both the identical a half of the earth, from a geostationary orbit, or more carefully from polar orbits to get extra detailed pictures. These low orbit weather satellites focus more on the research of the ambiance than on the current climate itself. Military Satellites Very similar to climate satellites, navy satellites are also used for observing the earth.
They typically have larger resolution cameras and so they use encryption as well.
Sometimes most of these satellites have very eccentric orbits to choose up delicate data from pleasant in addition to hostile nations. Scientific Satellites Observing the earth for scientific functions is also very good potential with satellites. Making maps with low polar orbits satellites for example, but also measuring the exact form of the earth, geological analysis, etc can all profit greatly from scientific satellites.
