Did you know? GPS relies on Einstein’s Theory of Relativity
According to Einstein's Theory of Relativity, speed and gravity have an impact on how time passes.

You are using GPS to navigate across a city and locate the fastest path with ease. However, did you know that the Theory of Relativity—one of Albert Einstein’s most astounding discoveries—is the foundation for this commonplace convenience?
How GPS Operates: A Navigation System for the Space Age
The 24 satellites that make up GPS’s constellation orbit 20,000 kilometres above the planet. These satellites help your smartphone determine your exact location by sending it time-stamped messages. However, the precision of the system is ensured by something exceptional that takes place behind the scenes.
Time Doesn’t Tick the Same Everywhere, According to Einstein’s Relativity
According to Einstein’s Theory of Relativity, speed and gravity have an impact on how time passes. Compared to clocks on Earth, GPS satellites’ clocks tick 38 microseconds quicker every day due to the lesser gravitational pull in space. This small discrepancy would result in significant location mistakes if left unchecked.
The Speed Factor: Motion Slows Time
According to Einstein’s Special Theory of Relativity, time dilation results from GPS satellites travelling at about 14,000 km per hour. The satellite clocks tick a little more slowly than the earthly clocks as a result of this impact.
Engineering Meets Einstein
GPS developers take into consideration both time dilation from speed and time speeding up in weaker gravity in order to preserve accuracy. Whether you’re driving to the closest store or managing international logistics, these exact modifications guarantee that GPS devices will direct you accurately.
From Relativity to Reality: Everyday Genius
GPS systems would be ineffective without Einstein’s discoveries since they would be off by 10 kilometres every day. His innovative views demonstrate how science influences our lives in ways we frequently ignore, bridging the gap between abstract physics and real-world applications.
Thank Einstein Next Time You Use GPS
GPS’s dependability, which can be used for everything from navigating city streets to saving lives in emergency situations, is evidence of relativity’s genius. Remember that Einstein’s genius is directing you every step of the way the next time your GPS comes to your rescue!
