How GPS Works: Mechanisms and Architecture
Global Positioning System (GPS) operates through a network of satellites that transmit signals. By calculating the time it takes for these signals to reach a receiver, GPS determines its position using trilateration. This involves measuring distances from at least three satellites to pinpoint a precise location on Earth. The system relies on atomic clocks to ensure that the timing is accurate, which is crucial for location precision.
Understanding the mechanics of GPS reveals its reliance on physics principles, such as the speed of light and the gravitational effects described by Einstein's theories.
Key points
- Satellites send signals at the speed of light.
- Receiver triangulates position based on signal timing.
- Requires a minimum of three satellites for accurate positioning.
