The Science Behind GPS Signals

This guide won’t get too technical, but understanding the basics of GPS is helpful. This short science lesson provides the foundation for learning how to use GPS beyond the basics.

First, the core of GPS capability is a constellation of satellites orbiting Earth. Each transmits signals picked up by receivers on the ground—any GPS-enabled device functions as a receiver. These signals carry data, such as the satellite’s position and the exact time the signal was sent.

The magic behind GPS’s precision lies in the atomic clocks on each satellite. These incredibly accurate clocks ensure the timing information within the signals is precise to within a few nanoseconds. GPS receivers rely on exact timing to calculate accurate distances and their position on Earth.

The Role of Satellite Networks in GPS

While the acronym “GPS” is often used generically, it technically refers to the United States’ Global Positioning System. However, several other Global Navigation Satellite Systems (GNSS) exist, each contributing to a more robust system for every country. Other satellite networks include:

1. GLONASS (Russia): Russia’s counterpart to GPS, GLONASS offers similar positioning services.
2. Galileo (EU): The European Union’s Galileo offers high-precision positioning and is interoperable with other systems.
3. BeiDou (China): China’s independently developed navigation system, BeiDou, provides global coverage and enhances positioning capabilities.

The beauty of some modern GPS receivers is their ability to simultaneously use signals from multiple GNSS networks. By incorporating data from GPS, GLONASS, Galileo, and BeiDou, receivers can access numerous satellites for more accurate, reliable data.
