Chinese market provides huge potential for growth of Global Positioning System (GPS)
Global Positioning System (GPS) Market in China 2008-2012
Global Positioning System (GPS) is a satellite-based navigation system, made up of a network of satellites. GPS is made up of three parts: satellites orbiting the Earth; control and monitoring stations on Earth; and the GPS receivers owned by users. GPS satellites broadcast signals from space, and are picked up and identified by the GPS receivers. Each GPS receiver then provides the three-dimensional location (latitude, longitude, and altitude) plus the time.
The receiver with an antenna is tuned to the frequencies of transmitted signal. The received signal is fed in the processor, along with display screen to map the location or calculate the time taken to reach the destination. The information can then be used by various systems (computer systems, communication devices for different functions).
