Holybro H-RTK F9P GNSS¶
The Holybro H-RTK F9P GNSS is an multi-band high-precision RTK GPS series by Holybro. This system provides multi-band RTK with fast convergence times and reliable performance, concurrent reception of GPS, GLONASS, Galileo and BeiDou, and fast update rate for highly dynamic and high volume applications with centimeter-accuracy. It uses a UBLOX F9P module, an IST8310 compass, and a tri-colored NTF LED indicator. It also has a integrated safety switch for simple and convenient operation.
Using RTK allows ArduPilot to get its position with centimeter-level accuracy, which is much more accurate than can be provided by a normal GPS.
There are three models of Holybro H-RTK F9P to choose from, each with different antenna design to meet different needs:
Wiring and Connections¶
All H-RTK GNSS models come with a GH 10-pin connector/cable that is compatible with the Pixhawk family and many other autopilots.
The cables/connectors may be modified to connect to other flight controller boards, using the Pin Map information provided above.
For normal operation, ArduPilot’s GPS parameter defaults will work for any serial port configured for
SERIALx_PROTOCOL = 5.
ArduPilot does not currently configure UBlox F9P GPS constellations. User must assure that the GPS is properly configured for his region and application. See U-Blox F9P Firmware Update
