The MG1009R 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.


  • Build-in high performance, low-power Realtek RTL8771Bchip set.
  • Concurrent reception of up to 2 GNSS (GPS, GLONASS, BeiDou) The following three operation modes and can be switched to each other by commands:
    1. Single GPS L1 operation mode
    2. BDS B1/GPS L1 dual-mode (default mode)
    3. GLONASS L1/GPS L1 dual-mode operation
  • Industry-leading -165 dBm navigation sensitivity
  • Low power consumption, the average power consumption is about 4.04mA@3.3V
  • Extremely fast TTFF at the low signal level
  • Miniature LCC package, compact size suitable for space-sensitive application(10.1mm x 9.7mm x 2.1mm)
  • Product variants to meet performance and cost requirements
  • Superior anti-spoofing and anti-jamming






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