Big Ideas - Episode 20 - GPS Technology

The video discusses the evolution and diverse applications of the Global Positioning System (GPS). Initially developed for navigation, GPS now serves various purposes, including wildlife conservation, law enforcement, cultural preservation, and urban management. Examples include tracking elephants in Kenya, monitoring police vehicles in China, aiding pygmies in Congo, and managing parking in the UK. The technology relies on signals from satellites to provide precise location data, which is crucial for its wide range of uses.

What is the primary reason for using four or more satellites in GPS technology?

• To ensure a wider coverage area

• To provide redundancy in case of satellite failure

• To achieve highly accurate local time

• To increase the speed of data transmission

How did GPS technology help in the Masai Mara game reserve in Kenya?
