What is GPS?
GPS is a satellite-based navigation system that consists of a network of satellites in space, ground control stations, and GPS receivers. The system works by triangulating signals from at least four GPS satellites to determine the precise location, velocity, and time of a GPS receiver on the ground. GPS is widely used in various industries, including aviation, military, transportation, and surveying.
Difference Between GAGAN and GPS
Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information anywhere on Earth. GPS is widely used for navigation, surveying, and tracking applications. GAGAN (GPS Aided Geo Augmented Navigation) is a satellite-based augmentation system developed by the Indian Space Research Organization (ISRO) to improve the accuracy and reliability of GPS signals in India and neighboring regions.
