What are GPS and GPRS respectively?

GPS is the abbreviation of English Global Positioning System.

GPRS (General Packet Radio Service) is the abbreviation of general packet radio service technology, which is a mobile data service that GSM mobile phone users can use and belongs to the data transmission technology in the second generation mobile communication.

GPRS is used for mobile phone network data transmission, and GPS is used for mobile navigation positioning software.

GPRS (General Packet Radio Service) is the abbreviation of general packet radio service technology, which is a mobile data service that GSM mobile phone users can use and belongs to the data transmission technology in the second generation mobile communication. GPRS is the continuation of GSM. GPRS is different from the way of continuous channel transmission in the past, and it is transmitted in the form of packets, so the cost borne by users is calculated based on the transmitted data, rather than using the whole channel, which is cheaper in theory. The transmission rate of GPRS can be increased to 56 or even 1 14Kbps.

GPS is the abbreviation of English Global Positioning System. GPS was started as a project of the US military in 1958 and put into use in 1964. In 1970s, the United States army, navy and air force jointly developed a new generation of satellite positioning system GPS. The main purpose is to provide real-time, all-weather and global navigation services for land, sea and air, and to be used for some military purposes such as intelligence gathering, nuclear explosion monitoring and emergency communication. After more than 20 years of research and experiments, it cost 30 billion dollars. By 1994, 24 GPS satellite constellations with global coverage of 98% have been deployed. In the field of machinery, GPS has another meaning: geometric product specifications (GPS for short). Another meaning is G/s(GB per second). GPS (General Processor Sharing) is a special term in processor sharing and network service quality control.
