Description
The M8N GPS Module with Compass is a high-precision navigation unit designed specifically for PIXHAWK flight control systems. Built around the advanced Ublox Neo-M8N receiver, this module delivers exceptional positioning performance with industry-leading sensitivity and fast satellite acquisition times. An integrated digital compass (typically HMC5883L or similar) provides accurate heading information for enhanced orientation and positioning .
Key Features
- Ublox Neo-M8N GNSS receiver supports concurrent reception of GPS/QZSS L1 C/A, GLONASS L10F, and BeiDou B1 for improved satellite availability and positioning reliability
- High navigation sensitivity of -167 dBm enables strong signal acquisition even in challenging environments
- Fast cold start time of approximately 26 seconds
- Built-in digital compass (integrated magnetometer) provides heading data to the flight controller
- Low noise 3.3V voltage regulator ensures clean power delivery to sensitive receiver components
- Includes fix indicator LEDs (typically blue) that flash to confirm satellite lock status
- Protective plastic housing shields the module from environmental exposure and electromagnetic interference
- Comes with a 26cm cable for flexible mounting options on drone frames
- Compact circular form factor (50mm diameter) with lightweight construction (32 grams with case)
