What was the first artificial satellite?
History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a beach ball (58 cm.or 22.8 inches in diameter), weighed only 83.6 kg. or 183.9 pounds, and took about 98 minutes to orbit the Earth on its elliptical path.
What are the types of satellite orbits?
There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface
What are the important classes of artificial satellites?
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.
How do satellite navigation systems work?
Satellite Navigation is based on a global network of satellites that transmit radio signals in medium earth orbit. ... The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning
