What are polar satellites and what are its uses? |
| Answer» A polar orbiting satellite closely parallels the earth\'s meridian lines, thus having a highly inclined orbit close to 90°. It passes over the north and south poles each revolution. As the earth rotates to the east beneath the satellite, each pass monitors an area to the west of the previous pass at intervals of roughly 90 to 100 minutes. These strips can be pieced together to produce a picture of a larger area.Uses: monitoring the weather, observing the Earth’s surface, military uses including spying. | |
