Question 4
State three differences between and geostationary satellites and polar satellites
Observation
Many candidates were able to differentiate between geostationary and polar satellites correctly. Some of the candidates could not give more than one difference.
EXPECTED RESPONSES:
Differences between geostationary and polar satellites
Geostationary |
Polar |
The period of revolution is the same as the period of rotation of the Earth/24 hours/1 day |
The period of revolution in orbit is not the same as the period of rotation of the Earth/varies |
Orbits directly along the equator/latitude |
Travels from pole to pole in orbit/along the longitude |
It appears to be stationary above a point on the Earth’s surface |
It is not always in the same position relative to the Earth |
Provides continuous coverage of specific regions/areas |
Provides global coverage |
