Let’s discuss GPS in detail.
What is the Global Positioning System (GPS) and how does it work?
The Global Positioning System (GPS) is a network of orbiting satellites operated by the United States Department of Defense that can determine the exact location of a person on Earth, using a set of three-dimensional coordinates. It is made up of 24 operational satellites which circle the globe in 12 hours, sending precise positioning signals.
In order to use GPS, the device receiving the positioning signals, such as a GPS receiver, must be able to read them and translate them into useful data. It does this by receiving a signal from at least four satellites at the same time. Each satellite will send a unique set of information, which the device uses to measure its relative distance to each satellite, the Doppler Effect, and timing of the signal. From there, the receiver is able to triangulate its position and determine the exact coordinates of the device’s current location.
GPS has been used in various industries such as agriculture, aviation, defense, transportation, and navigation. It is even used by individuals in order to stay safe in remote areas and navigate unknown terrain.
Overall, the Global Positioning System is an amazing tool for navigation and continues to be relied on for its precise and reliable positioning signals.
