UBlox GPS-RTK Breakout

This ZED-F9P-based GNSS HAT provides centimeter-level accuracy. It offers features such as multi-band RTK with quick convergence times, a high update rate, support for moving base RTK mode, simultaneous reception of four GNSS systems, support for augment positioning systems, accurate & quick positioning with minimal drifting, and exceptional anti-spoofing & anti-jamming capabilities.

• Supports Raspberry Pi series boards, Rock SBC series boards, Jetson Nano, Banana Pi, and more with a standard 40PIN GPIO extension header...
• Fast convergence times, centimeter-level accuracy, and high update rates for multi-band RTK
  
• Supports Moving base RTK mode, enabling centimeter-level accuracy and precise terminal navigation.
  
• Supports simultaneous receiving of 4 GNSS constellations (GPS, BeiDou, Galileo, and GLONASS) while yet using very little power.
  
• Enhance systems that provide service location positionings, such as SBAS, QZSS, IMES, and D-GPS
  
• Support for A-GNSS (Assisted GNSS), which speeds up initial positioning and increases acquisition sensitivity
  
• Features strong anti-spoofing and anti-jamming capabilities, -167dBm navigational sensitivity, and supports geo-fencing.
  
• Supports U-Center, a simple module configuration method
  
• Rechargeable batteries are supported via the onboard battery holder, which protects ephemeris data and hot starts.
