GNSS Modules

Global Navigation Satellite System (GNSS) modules receive signals from satellite constellations (GPS, GLONASS, Galileo, BeiDou) to determine precise location, velocity, and time.

• Common Types:
  • GPS (USA)
  • GLONASS (Russia)
  • Galileo (EU)
  • BeiDou (China)
• Key Features:
  • High sensitivity receivers
  • Low power consumption (e.g., u-blox, Quectel)
  • Support for multiple constellations (multi-GNSS)
  • UART/I2C/SPI interfaces
  • PPS output for timing applications
• Typical Applications:
  • Navigation systems
  • Asset tracking
  • Drones and robotics
  • Surveying and precision agriculture
• Design Tips:
  • Use active ceramic antennas with proper ground plane
  • Keep RF traces short and impedance-controlled (~50Ω)
  • Shield GNSS module from digital noise
  • Ensure clear view to sky in final product
