How GPS works? Trilateration explained on Make a GIF

Emma Steuer on Instagram: "GPS determines location through trilateration, which involves measuring the distance from multiple satellites to a receiver. At least three satellites are needed for a 2D location and four for a 3D location. Each satellite is equipped with an atomic clock, accurate to billionths of a second, which ensures the synchronization of time signals. This precise timing allows the GPS system to calculate distances accurately and provide exact positioning. .#gps #satellites #fac
