Satellite Systems
Muhtasari
A driver in a strange city is guided turn by turn to a hotel; a television channel reaches millions of homes at once; an emergency team is sent to the nearest casualty by a map that layers traffic, hospitals and population. All three lean on spacecraft thousands of kilometres above our heads. Satellite systems quietly carry position, data and broadcasts across the whole planet.
This lesson covers the three satellite applications the syllabus names: Global Positioning Systems (GPS) and satellite navigation, Geographic Information Systems (GIS), and media communication such as satellite television and phones. You will learn how at least three satellites fix a position, how GIS layers data on a map, how a signal is bounced off a satellite to the far side of the world, and the genuine advantages and disadvantages of each.
