The GPS chip is one of the key parts of the GPS system. The quality of the core chip determines the performance difference of different GPS products to a large extent, and determines the actual performance of the receiving terminal. It can be said that the GPS core chip is directly related to GPS. Product technical indicators and future development trends. With the continuous expansion of the GPS market, the chip industry can develop rapidly. At present, more than ten manufacturers have launched GPS chips. ^[2]

Non-standalone GPS

Used by laptop

After 2003, the GPS chip industry has sprung up like mushrooms. There are currently more than 10 manufacturers designing and producing GPS chips, including the United States SiRF,

About GPS "three generation chips"

There are many references to "three generation chips" in GPS. However, the merchant did not give a clear explanation, and most users did not know the substantial difference between the so-called "third-generation chip" and "second-generation", leading to some misunderstandings.

Currently, the most common GPS chips in the world are the US SIRF (Sirf)

SiRF's latest third-generation chip, SiRFstar III (GSW 3.0 / 3.1), uses a 200,000 times / frequency correlator to improve sensitivity.

On June 24, 2008, a research report released by Databeans indicated that the demand for Global Positioning System (GPS) ICs is increasing. Chip prices have fallen sharply and are beginning to look for more opportunities in the mobile phone market, as well as the mature PND and automotive markets. ^[5]

GPS equipment uses a US satellite system developed for military purposes that was launched many years ago. We use ground receivers to receive coordinate data from satellites. The receiving device transmits signals to these satellites, determines the location of the receiver, and calculates longitude, latitude, and even altitude. With continuous signal transmission to the satellite, the receiver can collect data within a set time and calculate the speed, distance, and estimated time to reach a preset point. ^[5]

The application of GPS technology has been affected by cost, but now chip prices have dropped significantly, more and more mobile phones and cars are equipped with GPS functions, and the technology has continued to gain popularity in the consumer sector. Shipments of GPS electronic equipment reached 126 million units in 2007, with a compound annual growth rate of 20%, and will reach 500 million units in 2013. ^[5]
