Final answer:
GNSS stands for Global Navigation Satellite System and includes various satellite navigation systems. GPS is a specific system within the GNSS.
Step-by-step explanation:
GNSS stands for Global Navigation Satellite System. It is a term used to describe a system of satellites that provide positioning, navigation, and timing services to users on Earth. GNSS includes various systems such as GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo, and BeiDou. While GPS is a specific system within the GNSS, it is commonly used as a generic term to refer to any satellite-based navigation system.
GPS, which stands for Global Positioning System, is a navigation system that uses a network of satellites to determine the location of a receiver on Earth's surface. It works by calculating the distance between the receiver and multiple satellites to triangulate the receiver's position. GNSS, on the other hand, refers to the broader system that includes GPS as well as other satellite navigation systems.
