Detailed explanation-1: -QZSS is a regional GNSS owned by the Government of Japan and operated by QZS System Service Inc. (QSS). QZSS complements GPS to improve coverage in East Asia and Oceania.

Detailed explanation-2: -A GPS (global positioning system) unit uses information from United States satellites to provide an accurate location almost anywhere on Earth. The global positioning system (GPS) is a network of satellites and receiving devices used to determine the location of something on Earth.

Detailed explanation-3: -GLONASS supplementation of GPS systems also improves positioning in high latitudes (north or south). Development of GLONASS began in the Soviet Union in 1976. Beginning on 12 October 1982, numerous rocket launches added satellites to the system, until the completion of the constellation in 1995.

Detailed explanation-4: -What is GPS? The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use.

Detailed explanation-5: -GPS is a system of 30+ navigation satellites orbiting the Earth. We know their location precisely because they invariably send out signals. The GPS receiver in your phone receives these signals. Once the receiver calculates its distance from four or more GPS satellites, it can figure out exactly where you are.
