Holybro H-RTK F9P Ultralight RTK GNSS Module

The Holybro H-RTK F9P Ultralight puts a u-blox ZED-F9P multi-band RTK receiver, an IST8310 compass and an integrated helical antenna into a module weighing under 25 g, for mapping, survey and research UAVs where every gram counts. With RTK corrections it gives centimetre-level positioning to Pixhawk-standard flight controllers.

Key features

• Concurrent multi-band tracking of GPS/QZSS (L1C/A, L2C), GLONASS (L1OF, L2OF), Galileo (E1B/C, E5b) and BeiDou (B1I, B2I)
• RTK accuracy of 1 cm + 1 ppm horizontal; 0.5 m CEP with DGNSS and 2.0 m CEP standalone
• Integrated helical antenna, so there is no separate antenna or mast to mount
• IST8310 magnetometer on board for heading
• Fast fixes: 1 s hot start, 20 s warm start, 35 s or less cold start

RTK needs a correction source: a second F9P module as a ground base station, or an NTRIP service fed through your ground control station, plus a telemetry link to carry the corrections to the aircraft.
