The GPS module (Global Positioning System Module) is a satellite navigation and positioning device that integrates radio frequency reception, baseband signal processing, and positioning algorithm. Modern GPS modules have evolved from a single GPS system to a high-precision positioning solution that supports multiple constellations (GNSS), and are widely used in applications such as vehicle navigation, unmanned aircraft, the Internet of Things, and wearable devices.

The size specifications of the GPS module have evolved from large to small, resulting in several industry-standard packages:

9.7*10.1MM

12.2*16MM

17*22MM

Currently, there are such satellite signals in the world.

GPS (USA)

GLONASS (Russia)

BDS (China)

Galileo  (European Union)

QZSS  (Japan)

IRNSS/NavIC (India)

GNSS modules are usually classified as single-mode or multi-mode. Single frequency, dual frequency
