Satellite

9.1 Satellite
 
Satellite
Satellite: an object which orbits planets or stars
 
 Types of satellite orbits
Types of Satellite Orbits
 
Orbit shapes
  • Circular
  • Elliptical
 
Specific positions of satellites in the orbits
  • Apogee
  • Perigee
 
Relationship between orbital height and satellite velocity
  • The higher the orbital height of a satellite, the lower the satellite speed for it to remain in orbit 
  • This is because the gravitational force on a satellite decreases when the orbital height of the satellite increases
 
Methods of sending launch vehicles into orbit
  • Launch vehicles: used to send satellites or spacecraft into outer space
    • Expendable launch vehicle (ELV)
    • Reusable launch vehicle (RLV)
  • Ways to send launch vehicles into orbit:
    • Directly into orbit
    • Hohmann transfer orbit
 
Zero gravity
The condition when no significant gravitational force effect is felt
 
Impact of rapid development in space technology
  • Increased waste in space / space junk
  • Increase in research and development activities
