The MG1612R GNSS modules are concurrent GNSS receivers that can receive and track multiple GNSS systems: BDS ,GPS and GlONASS (choose two of the three). The modules integrate with Realtek's new generation chip RTL8771B, which is designed to receive and track BDS B1/GPS L1/GLONASS L1 signals. High sensitivity down to -165dBm , low power consumption and miniature LCC package make it ideal for designing and manufacturing of small size positioning devices .


  • Automotive navigation
  • Personal positioning
  • Fleet management
  • Mobile phone navigation
  • Marine navigation
