Drone GPS & GNSS Modules
Drone GPS modules give the flight controller position, speed and, with a compass or dual antennas, heading. Compare Chinese GPS and GNSS modules, RTK receivers, OEM boards and antennas, and request quotes.
RTK, heading & base stations
Centimetre-level positioning with correction data from a base station or network, plus dual-antenna heading modules and base stations.

What to check before you buy
- Constellations and bands
- Single-band (L1) modules suit most flight controllers; multi-band receivers fix faster and hold RTK better under trees and near buildings.
- Accuracy figure
- Compare like with like: standalone or RTK, horizontal or vertical, and CEP or RMS.
- Update rate
- Ask for the navigation rate with all constellations on, not only the single-system maximum.
- Interface
- UART/I2C or DroneCAN, the connector type, and which flight controller firmware it has been tested with.
- Compass and heading
- Check the onboard magnetometer, or a dual-antenna module if you need heading without a compass.
- Corrections
- For RTK, decide on your own base station or a network correction service, and how corrections reach the drone.
Drone GPS FAQ
How accurate is an RTK module?
RTK modules in this catalogue state horizontal accuracy of about 1 cm + 1 ppm, for example 0.01 m + 1 ppm CEP for the Holybro H-RTK ZED-F9P Rover, when they receive correction data.
Do these modules work with ArduPilot and PX4?
Many do. ArduPilot supports DroneCAN GPS modules from several makers, and suppliers such as CUAV list ArduPilot and PX4 compatibility. Confirm the connector and firmware for your flight controller.
