GPS vs GNSS
Summary: Difference Between GPS and GNSS is that a global positioning system (GPS) is a navigation system that consists of one or more earth-based receivers that accept and analyze signals sent by satellites in order to determine the receiver’s geographic location. While GNSS stands for Global Navigation Satellite System, which refers to the group of satellites that are providing signals from space used to transmit and poisition data.
GPS
A global positioning system (GPS) is a navigation system that consists of one or more earth-based receivers that accept and analyze signals sent by satellites in order to determine the receiver’s geographic location. A GPS receiver is a handheld, mountable, or embedded device that contains an antenna, a radio receiver, and a processor. Many include a screen display that shows an individual’s location on a map. Some also function as a portable media player. Many mobile devices such as smart phones have GPS capability built into the device or as an add-on feature. Some users carry a handheld GPS receiver; others mount a receiver to an object such as an automobile, boat, airplane, farm and construction equipment, or computer.
The first and most used application of GPS technology is to assist people with determining where they are located. The data obtained from a GPS, however, can be applied to a variety of other uses: creating a map, ascertaining the best route between two points, locating a lost person or stolen object, monitoring the movement of a person or object, determining altitude, and calculating speed. Many vehicles use GPSs to provide drivers with directions or other information.
GNSS
GNSS stands for Global Navigation Satellite System, which refers to the group of satellites that are providing signals from space used to transmit and poisition data. And by definition GNSS provides a whole Global Coverage. GNSS itself includes several positioning terms like GPS, GLONASS, Galileo, Beidou and other regional systems. GNSS is used worldwide to provide a group of satellites to give us accuracy, redundancy and availability 24/7. Often, Satellite systems do not fail, but if they fail through GNSS they find singal from another satellite. Another benefit is a group of satellites, if a connection from one satellite is weak we can get it from another satellite.
