Low power consumption Multi-GNSS Receiver Module
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.
Features
- 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:
- Single GPS L1 operation mode
- BDS B1/GPS L1 dual-mode (default mode)
- 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
