TELECOMMUNICATION ~ Difference between GPS and GPRS

 

     GPS and GPRS are terms that sound similar but are absolutely different. The difference between GPS and GPRS is that GPS is a satellite navigation system while GPRS is used to provide cellular data services.

    GPS facilitates a range of applications such as operations, mapping, power grid, telecommunications, intelligent vehicles, etc. On the other hand, GPRS is used to enable high data rate services (voice and data) on wireless devices or in a cellular network such as real-time video calls on mobiles, etc.

Definition of GPS: 

    GPS (Global Positioning System) is a receiving radio (which may be inside a cell phone or personal tracking device) that listens to broadcasts from GPS satellites to determine its position. Using the information received in data transmissions from 3 or more satellites can allow such a GPS device to locate its position on Earth ... to within a few dozen meters.

Definition of GPRS:

    GPRS (General Packet Radio Service) is a data transmission technology used by GSM 2G cellular phones. It allows the transmission and reception of general data using IP (Internet Protocol) ... at a relatively slow rate compared to 3G (called HSPA) or 4G (called LTE) cellular.

 Key differences between GPS and GPRS:

• GPS stands for Global Positioning System which provides a positioning service while GPRS stands for General Packet Radio Service which provides integrated wireless voice and data services.

•     GPS specifies the location of the object in terms of latitude and longitude. In contrast, GPRS is the enhanced version of GSM that provides high data rates for cellular systems.

•     GPS uses a constellation of 24 satellites that orbit the earth to locate the position of an object. GPRS, on the other hand, uses ground towers to communicate.

•     GPRS requires only one station while GPS requires three stations to operate.

•     GPS is very expensive because the satellites used are expensive. On the other hand, GPRS is less expensive.

•     GPRS is limited in its range and only works well in areas where the BST (Base Transceiver System) is installed. On the other hand, the GPS system covers a wider range and can work well even in the sea and sky. 

In short:

    GPS and GPRS are different terms and serve different purposes. GPS is a satellite-based positioning system, which includes navigation, mapping and GIS (geographic information system). While, GPRS is used to enable high data rate services (voice and data) on wireless devices or in a cellular network such as real-time video calls on mobiles, etc.
