The GPS module is an integrated circuit that integrates an RF RF chip, a baseband chip, and a core CPU, and adds related peripheral circuits.
At present, most of the GPS chips of the GPS module are based on the SiRF III series, which is the world's largest market share. Because the GPS module uses different chipsets, the performance and price are different. The GPS module with SIRF three-generation chipset has the best performance, and the price is much more expensive than the GPS chipset such as MTK or MSTAR. At this stage, the chip upgrade is also continued. For example, sirf4 and then sirf5, the overall sensitivity is improved a lot, shortening the positioning time, and also helping the customer to quickly enter the positioning application state.
