Story 1 on Satellite navigation

How does GPS work and where is it used

Background information on the transmission:

During the next four weeks, the ESA TV Service will transmit a four-part series of short, topical stories on satellite navigation, particularly on its use in cars and road traffic management.

Today’s transmission explains how satellite positioning and navigation using the Global Positioning System (GPS) works, and it looks into the limitations of the GPS system, particularly for safety-critical areas like commercial air traffic navigation.

Each of the four transmissions is made of a 4-minute A-roll and a B-roll. The A-roll carries split audio tracks (English and ambient sound), and the B-roll clean international sound.
