GPS first operation | Birth of the Global Positioning System | Techday, December 8th
On this TECHDAY in history, on December 8th 1993, the GPS (Global Positioning System) goes into operation.
The U.S. Department of Defense developed the positioning system, intended for military use. However, the system quickly proved to have many civilian applications as well, such as navigation for cars and boats, location tracking for emergency services, and even for tracking wildlife.
The GPS network consists of 24 to 32 satellites that cover the entire planet evenly with their signal, so there is no risk of being disoriented anywhere. All the satellites are located at an altitude of 20,200 km above sea level. They make two revolutions around the Earth every 24 hours.
The Global Positioning System operation has highly facilitated today’s world overall. It is now a vital tool for many industries, used in a wide range of applications, including transportation, agriculture, surveying, and mapping. The system continues to be updated and improved. Elements of improvement are the launch of more advanced satellites and the development of new technologies such as assisted GPS (A-GPS). It uses data from cellular networks to improve location accuracy.
