  1. P3 1.8 SATELLITES • Learning objectives • Be able to explain: • the period of an orbit • a geostationary orbit

  2. P3 1.8 SATELLITES Imagine launching a satellite from a very tall mountain:

  3. P3 1.8 SATELLITES Imagine launching a satellite from a very tall mountain:

  4. P3 1.8 SATELLITES Imagine launching a satellite from a very tall mountain: Moving in circles needs: 1. high sideways speed 2. central force

  5. P3 1.8 SATELLITES Imagine launching a satellite from a very tall mountain: Moving in circles needs: 1. high sideways speed 2. central force The period of an orbit is the time taken to make one complete orbit.

Observational satellites - equipped with telescopes to study planets , stars galaxies, outer space 2. Geostationary Communications satellites - link different countries with TV, radio telephone Orbit time = 24hrs , Satellite stays exactly in the same place when viewed from earth at 36,000km above the equator.

  12. P3 1.8 SATELLITES 3. Polar monitoring satellite * has a low polar orbit, the whole earth is scanned as it spins below. Orbit time: 75 mins Use: weather monitoring
