UBlox GPS-RTK HAT Board
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.
It is pretty simple to enable GNSS functionality for your ROCK SBC, Raspberry Pi, Banana Pi, etc., by just hooking it up to the SBCs.
- It 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
- It supports moving base RTK mode, enabling centimeter-level accuracy and precise terminal navigation.
- It uses very little power and supports the simultaneous receiving of four GNSS constellations (GPS, BeiDou, Galileo, and GLONASS).
- 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
- It features anti-spoofing solid 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.
